However, MEMS flexures can be used to serve a variety of additional purposes, including motion control, thermal coefficient of expansion (TCE) compensation and alignment. In optical products, such as MEMS based cell phone cameras, flexures enable MEMS to interface seamlessly with separate components manufactured using more traditional processes, such as plastic injection molding. This talk will present some of these unique flexure systems, and describe some of the considerations in their design. As an example, the MEMS flexures used in the cell phone camera for Motorola?s Ming A1600 will be described. Speaker Bio After 10 years at NASA?s Jet Propulsion Laboratory working on high precision laser metrology and MEMS based gyroscopes, Roman Gutierrez co-founded SiWave (aka Siimpel) in 2000 to develop MEMS optical switches. The company was acquired by Tessera in 2010, and Roman continues as CTO/VP Engineering for the MEMS division. Mr. Gutierrez is a pioneer in the application of MEMS and Optics to new product development and has authored 52 issued patents and over 30 patents pending. He received his BS in Applied Physics from the California Institute of Technology, and his MS in Electrical Engineering from the University of California Santa Barbara. -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <4C0576AF.5080508@stanford.edu> SNF Lab Members: One of the big air handling units that supplies air to the lithography aisles has experienced a bearing failure. The bearing is being shipped today and should be here tomorrow morning. During that time there will be reduced airflow in that area. If you are doing critical work you should check the temperature and humidity in that area before proceeding. It is my understanding that the area of lithography that will be most affected by this outage is the aisle that runs in front of the Headway spinner and the Blue M bake ovens. We will provide an update when the air handler is back in service or if it is not in service by the end of tomorrow.

Currently, electrophysiological interventions are performed under fluoroscopic guidance, which does not provide adequate soft-tissue resolution and exposes the patient and the operator to harmful ionizing radiation. Intracardiac echocardiography (ICE) provides real-time anatomical information that has proven valuable in reducing the fluoroscopy time and enhancing procedural success. Currently, piezoelectric transducer technology dominates the ultrasound imaging market. For ICE catheters, however, the limited available space and stringent packaging requirements challenge efforts to build a piezoelectric transducer array at the tip of the catheter for forward-looking imaging. This difficulty arises from the piezoelectric transducer manufacturing process, which is based on meticulous and labor-intensive steps. I have developed two types of multi-functional forward-looking ICE catheters using capacitive micromachined ultrasonic transducer (CMUT) technology: MicroLinear (ML) and Ring catheters. The ML catheter enables real-time forward-looking 2-D imaging using a 1-D CMUT array. The Ring catheter uses a ring-shaped 2-D CMUT array that enables real-time forward-looking 3-D imaging. Both of these catheters are equipped with custom-designed front-end circuits that are integrated with the transducer at the catheter tip. In this talk, I will describe the main components of these catheters. I will show how the integrated front-end IC improves the SNR by more than 20 dB. I will explain how all the components are integrated in the tight space available for full catheter construction with 100% yield. This task involved numerous challenges, especially in the case of Ring catheter, wherein, I successfully flip-chip bonded 8 IC?s (1.2 mm ? 1 mm) and a Ring array (2.5 mm in diameter) to a flexible substrate with a total of 244 interconnects. I will also present in-vivo imaging results obtained using these catheters. In the last part of the talk, I will introduce a new CMUT structure that exhibits ideal piston-like plate movement. Contrary to a conventional CMUT, the top plate in the proposed structure does not need to be operated in flexural mode. This results in significantly improved fill-factor, and thus, a more efficient transducer. -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <4C091709.203@stanford.edu> SNF Lab Members: You have likely noticed that we have made some changes to the vacuum wands in the cleanroom. In particular, they are now being held in plastic supports that make it easier to keep the "business end" of the wand from hitting nearby sources of contamination such as walls, plastic tubing, etc. We have also placed a quartz sheath around the stainless steel shaft in hopes of reducing the chances that accidental contact between stainless steel and clean wafers, boat, or cantilevers can cause metal-induced contamination. Given the fact that a number of these vacuum wands have chipped quartz tips and we've already replaced quartz sheaths, it is clear that some are not handling these items with sufficient care. In general, these quartz tips are the one thing that is allowed to touch a wafer after they have been cleaned and before they go into most high-temperature operations. As a result, it is essential that everyone handle these with extreme care. The quartz tip and sheath should never touch anything but your wafers, they should never be bumped against anything, nor should they ever be touched with a gloved hand. Over and above their cost ... each tip costs $155 ... careful handling of these quartz vacuum wands is vital to those who have the most critical cleanliness needs. Even if you believe that your wafers do not have critical cleanliness requirements, a number of people in the lab are processing wafers that are exceedingly sensitive to contamination. If you contaminate the quartz tips in any way, their devices will likely suffer. Please be particularly careful when handling the quartz-tipped vacuum wands.

O'Sullivan Department of Electrical Engineering Research Advisor: Prof. James S. Harris Date: Wednesday, June 16th, 2010 Time: 10:00 am (Refreshments 9:45am) Location:Clark Center Auditorium (below the patio) http://campus-map.stanford.edu/index.cfm?ID=07-340 Abstract: Molecular imaging is an established technique used to visualize and quantify functional information about biological processes in living systems. Specifically, the ability to image fluorescence is a powerful tool considering the wealth of fluorescent probes/proteins that are used in drug discovery and therapeutic evaluation, in studying development and treatment of cancer, in tracking stem cell growth and proliferation in small animals. Fluorescence sensing is also an emerging technique for use in humans. Current approaches to detect fluorescence in vivo rely on devices which use bulky instrumentation, generally requiring anesthetized animal models, and restrict sensing to discrete snapshots in time. Thus, there is need for continuous, long-term monitoring of fluorescent probes. In this talk, I present our design and fabrication of a miniaturized fluorescence sensor for direct implantation which enable continuous and long-term sensing in freely-moving subjects. The monolithically-integrated, laser-based sensor incorporates the basic optical components of a fluorescence system for sensing Cy5.5 fluorescent dye. I will discuss the materials and microfabrication challenges overcome to achieve the compact integration, as well as the device sensitivity to /in vitro/ and /in vivo/ concentrations of Cy5.5. I will present our efforts and the benefits of using the sensor to monitor the binding kinetics of a molecular probe in cancer tumors and will demonstrate continuous sensing with the sensor implanted in live mice. -------------- next part -------------- An HTML attachment was scrubbed...

Refreshments at 4:00/* */Presented by the Stanford Optical Society/* */ /* /Abstract/// The ability of fluorescence microscopy to perform noninvasive imaging of live samples with molecular specificity has made it one of the most powerful imaging techniques to study cellular processes. However, the diffraction of light limits the spatial resolution of conventional fluorescence microscopy, leaving many biological structures too small to be observed in detail. To overcome this limit, we have developed the Stochastic Optical Reconstruction Microscopy (STORM) technique. It utilizes the photoswitching of fluorophores to isolate their spatially overlapped images, and single-molecule localization to reconstruct the sample structure with the position of labeled fluorescent probes. We have achieved a 20-30 nm lateral resolution in cellular samples, which is an improvement by more than an order of magnitude over conventional fluorescence microscopy. The incorporation of three-dimensional (3D) single molecule localization further enables 3D STORM of a whole cell with 50-60 nm axial resolution. We have also created photoswitchable fluorophores for multicolor imaging by combinatorial pairing of various activator dyes and reporter dyes. We have demonstrated the ability of STORM to visualize structures unresolvable by conventional fluorescence microscopy, including in vitro reconstituted clathrin-mediated endocytic machinery and synapses in the olfactory system. /About our speaker/// Tim Day PhotoDr. Bo Huang received his B.S. degree in Chemistry from Peking University in China in 2001.

Harris Date: Friday, June 11, 2010 Time: 2:00 p.m. Location: CIS-X 101 Title: Sillicon-Gemanium Electroabsorption Modulator Optical interconnections between electronics systems have attracted significant attention and development for a number of years because optical links have potential advantages for higher speed, lower power, and interference-immunity. With increasing system speed and greater bandwidth requirements, the distance over which optical communication is useful has continually decreased to where the frontier is now at the chip-to-chip and on-chip levels. Successful, monolithic integration of photonics and electronics will significantly reduce the cost of optical components and further combine the functionalities of chips on the same or different boards or systems. The quantum-confined Stark effect (QCSE) is a strong, electric field dependent change in optical absorption that has been observed in several groups of quantum well materials. The QCSE is used extensively for high-speed, low power dissipation optical modulators, for example, in telecommunications, and has also been used in large arrays of low power devices. To this point, most examples of the QCSE have been in III-V semiconductor quantum wells, such as GaAs with AlGaAs barriers , or InGaAs with InP barriers. While these modulators are all based upon direct bandgap semiconductors, QCSE has been demonstrated in indirect bandgap AlGaAs/AlAs quantum wells and we previously demonstrated the QCSE in Ge quantum wells with SiGe barriers. The group IV quantum well structures are especially interesting as they would enable fully integrated modulators and driver circuits in silicon ICs for telecommunications applications and potentially on-chip communications. With reasonably low-power modulators, In this talk, We present observations of quantum confinement and quantum-confined Stark effect (QCSE) electroabsorption in Ge quantum wells with SiGe barriers grown on Si substrates. Though Ge is an indirect gap semiconductor, the resulting effects are at least as clear and strong as seen in typical III-V quantum well structures at similar wavelengths. We also designed and fabricated a coplanar high-speed modulator and demonstrated small signal modulation at 35GHz and a 3.125GHz eye diagram. That shows group IV quantum well structure has the potential to build high-speed optical communication components. -------------- next part -------------- An HTML attachment was scrubbed...

Moerner Refreshments at 3:00 p.m. 11 June 2010 @ 3:15 p.m. Location: Applied Physics Building, Room 200 ABSTRACT Plasmonic nanoantennas can concentrate light beyond the diffraction limit and create highly enhanced local fields, leading to increased Raman scattering and, in some cases, increased fluorescence from nanoscale emitters. Gold bowtie nanoantennas provide a highly enhancing structure that is more controllable and amenable to integration than other geometries such as sharp metal tips and colloids. We have enhanced a single molecule's fluorescence by a factor of 1,300 by coupling it to a bowtie nanoantenna, ten times higher than previously reported for any other plasmonic structure. Electromagnetic simulations reveal that this enhancement is a result of greatly increased absorption of light as well as a shortened excited state lifetime, leading to enhancement of the intrinsic quantum efficiency by an estimated factor of nine, despite additional non-radiative ohmic losses. Measurements of enhanced single-molecule fluorescence for molecules both in rigid polymers and in solution show that bowtie nanoantennas can be used for high-contrast selection of single nanoemitters in crowded environments. -------------- next part -------------- An HTML attachment was scrubbed...

Brongersma 10 June 2010 @10:15 A.M. (Refreshments 10:00 A.M.) Location: Allen Building (formerly CIS-X), Room 101 ABSTRACT The development of integrated electronic and photonic circuits has led to remarkable data processing and transport capabilities that permeate almost every facet of our daily lives. Scaling these devices to smaller and smaller dimensions has enabled faster, more power efficient and inexpensive components but has also brought about a myriad of new challenges. One very important challenge is the growing size mismatch between electronic and photonic components. To overcome this challenge, we will need to develop radically new device technologies that can facilitate information transport between nanoscale components at optical frequencies and form a bridge between the world of nano-electronic and micro-photonics. Plasmonics is an exciting new field of science and technology that aims to exploit the unique optical properties of metallic nanostructures to gain a new level of control over light-matter interactions. The use of nanometallic (plasmonic) structures may help bridge the size gap between the two technologies and enable an increased synergy between chip-scale electronics and photonics. In the first part of the presentation I will analyze the performance of a surface plasmon-polariton all-optical switch that combines the unique physical properties of small molecules and metallic (plasmonic) nanostructures. The switch consists of a pair of gratings defined on an aluminum film coated with a thin layer of photochromic (PC) molecules. The first grating couples a signal beam consisting of free space photons to SPPs that interact effectively with the PC molecules. These molecules can reversibly be switched between transparent and absorbing states using a free space optical pump. In the transparent (signal "on") state, the SPPs freely propagate through the molecular layer, and in the absorbing (signal "off") state, the SPPs are strongly attenuated. The second grating serves to decouple the SPPs back into a free space optical beam, enabling measurement of the modulated signal with a far-field detector. We confirm and quantify the switching behavior of the PC molecules by using a surface plasmon resonance spectroscopy. The quantitative experimental and theoretical analysis of the nonvolatile switching behavior guides the design of future nanoscale optically or electrically pumped optical switches. In the second part of my presentation I will provide a critical assessment of the opportunities for use of plasmonic nanostructures in thin film solar cell technology. Thin-film solar cells have attracted significant attention as they provide a viable pathway towards reduced materials and processing costs. Unfortunately, the materials quality and resulting energy conversion efficiencies of such cells is still limiting their rapid large-scale implementation. The low efficiencies are a direct result of the large mismatch between electronic and photonic length scales in these devices; the absorption depth of light in popular PV semiconductors tends to be longer than the electronic (minority carrier) diffusion length in deposited thin-film materials. As a result, charge extraction from optically thick cells is challenging due to carrier recombination in the bulk of the semiconductor. If light absorption could be improved in ultra-thin layers of active material it would lead directly to lower recombination currents, higher open circuit voltages, and higher conversion efficiencies. In this part of the talk, I will discuss how extreme light concentration ability of plasmonic structures can improve the overall performance of thin film solar cells with broadband absorption enhancements. I will present a combined computational\experimental study aimed at optimizing plasmon-enhanced absorption using periodic and aperiodic metal nanostructure arrays. -------------- next part -------------- An HTML attachment was scrubbed...

Refreshments at 4:00/* */Presented by the Stanford Optical Society/* */ /* /Abstract/ The ability of fluorescence microscopy to perform noninvasive imaging of live samples with molecular specificity has made it one of the most powerful imaging techniques to study cellular processes. However, the diffraction of light limits the spatial resolution of conventional fluorescence microscopy, leaving many biological structures too small to be observed in detail. To overcome this limit, we have developed the Stochastic Optical Reconstruction Microscopy (STORM) technique. It utilizes the photoswitching of fluorophores to isolate their spatially overlapped images, and single-molecule localization to reconstruct the sample structure with the position of labeled fluorescent probes. We have achieved a 20-30 nm lateral resolution in cellular samples, which is an improvement by more than an order of magnitude over conventional fluorescence microscopy. The incorporation of three-dimensional (3D) single molecule localization further enables 3D STORM of a whole cell with 50-60 nm axial resolution. We have also created photoswitchable fluorophores for multicolor imaging by combinatorial pairing of various activator dyes and reporter dyes. We have demonstrated the ability of STORM to visualize structures unresolvable by conventional fluorescence microscopy, including in vitro reconstituted clathrin-mediated endocytic machinery and synapses in the olfactory system. /About our speaker/ Tim Day PhotoDr. Bo Huang received his B.S. degree in Chemistry from Peking University in China in 2001.

Harris Date: Friday, June 11, 2010 Time: 2:00 p.m. Location: CIS-X 101 Title: Sillicon-Gemanium Electroabsorption Modulator Optical interconnections between electronics systems have attracted significant attention and development for a number of years because optical links have potential advantages for higher speed, lower power, and interference-immunity. With increasing system speed and greater bandwidth requirements, the distance over which optical communication is useful has continually decreased to where the frontier is now at the chip-to-chip and on-chip levels. Successful, monolithic integration of photonics and electronics will significantly reduce the cost of optical components and further combine the functionalities of chips on the same or different boards or systems. The quantum-confined Stark effect (QCSE) is a strong, electric field dependent change in optical absorption that has been observed in several groups of quantum well materials. The QCSE is used extensively for high-speed, low power dissipation optical modulators, for example, in telecommunications, and has also been used in large arrays of low power devices. To this point, most examples of the QCSE have been in III-V semiconductor quantum wells, such as GaAs with AlGaAs barriers , or InGaAs with InP barriers. While these modulators are all based upon direct bandgap semiconductors, QCSE has been demonstrated in indirect bandgap AlGaAs/AlAs quantum wells and we previously demonstrated the QCSE in Ge quantum wells with SiGe barriers. The group IV quantum well structures are especially interesting as they would enable fully integrated modulators and driver circuits in silicon ICs for telecommunications applications and potentially on-chip communications. With reasonably low-power modulators, In this talk, We present observations of quantum confinement and quantum-confined Stark effect (QCSE) electroabsorption in Ge quantum wells with SiGe barriers grown on Si substrates. Though Ge is an indirect gap semiconductor, the resulting effects are at least as clear and strong as seen in typical III-V quantum well structures at similar wavelengths. We also designed and fabricated a coplanar high-speed modulator and demonstrated small signal modulation at 35GHz and a 3.125GHz eye diagram. That shows group IV quantum well structure has the potential to build high-speed optical communication components. -------------- next part -------------- An HTML attachment was scrubbed...

Kenny Date: Wednesday, June 16th, 2010 Time: 2pm (Refreshments and snacks at 1:45pm) Location: Allen Building (formerly CIS-X) Auditorium, Room 101 Abstract: Building an understanding of the fundamental mechanisms that contribute to adhesion, friction, and wear at the micro- and nano- scales is vitally important to develop reliable micro-devices that involve contacting and sliding surfaces. When dimensions are reduced down to the micro- and nano-scale, the surface area-to-volume ratio increases significantly and surface forces begin to play a dominant role in adhesion and friction. The complicated and often unreliable behavior of contacting and sliding surfaces has limited their adoption in many microelectromechanical systems (MEMS). This study examines the effects of the contact conditions on the friction forces and wear rate to enhance the current understanding of friction at the small scale and lead to the design of reliable sliding surfaces in MEMS devices. In this presentation, I will discuss the development of a unique experimental setup where friction forces are solely responsible for the measured motion. Friction is measured between an array of single crystal silicon MEMS probe tips and a flat silicon surface. Contact between the surfaces occurs at AFM-like tips that are located at the end of compliant cantilevers. Friction force results from arrays with varying numbers of tips show that the friction forces depend heavily on the true contact area between two sliding surfaces. This work also takes a careful look at the conditions that affect the wear rate of the tips. Methods such as reducing the contact pressure per tip and allowing mechanical compliance of the contacting surface are shown to minimize the detrimental effects of wear. -------------- next part -------------- An HTML attachment was scrubbed...

Harris Date: Wednesday, June 16th, 2010 Time: 10:00 am (Refreshments 9:45am) Location: Clark Center Auditorium (below the patio) http://campus-map.stanford.edu/index.cfm?ID=07-340 Abstract: Molecular imaging is an established technique used to visualize and quantify functional information about biological processes in living systems. Specifically, the ability to image fluorescence is a powerful tool considering the wealth of fluorescent probes/proteins that are used in drug discovery and therapeutic evaluation, in studying development and treatment of cancer, in tracking stem cell growth and proliferation in small animals. Fluorescence sensing is also an emerging technique for use in humans. Current approaches to detect fluorescence in vivo rely on devices which use bulky instrumentation, generally requiring anesthetized animal models, and restrict sensing to discrete snapshots in time. Thus, there is need for continuous, long-term monitoring of fluorescent probes. In this talk, I present our design and fabrication of a miniaturized fluorescence sensor for direct implantation which enable continuous and long-term sensing in freely-moving subjects. The monolithically-integrated, laser-based sensor incorporates the basic optical components of a fluorescence system for sensing Cy5.5 fluorescent dye. I will discuss the materials and microfabrication challenges overcome to achieve the compact integration, as well as the device sensitivity to in vitro and in vivo concentrations of Cy5.5. I will present our efforts and the benefits of using the sensor to monitor the binding kinetics of a molecular probe in cancer tumors and will demonstrate continuous sensing with the sensor implanted in live mice.

They are showing up more and more in automobiles, cell phones, televisions and many other places. The packaging of these devices is critical to their performance and reliability and must be carefully considered in their overall system design. Due to strict requirements and the fragile nature of these devices, the packaging often represents a significant portion of the total cost of a MEMS product. Stanford University, jointly with Bosch, developed a wafer-scale encapsulation method in which MEMS devices are encapsulated as a part of their fabrication. This process, now used by SiTime, has been dubbed the ?epi-seal? process by virtue of its use of an epitaxial silicon reactor to seal the cavities containing the devices. Devices are cleaned in-situ in the epitaxial silicon reactor just prior to sealing, resulting in a package environment that is very clean and stable. Because this is a batch process, the overall packaged device cost is very low. One significant limitation with this process, however, is that devices are limited to small (less than 2?m) trenches, thus prohibiting large displacements and common MEMS structures such as comb drives. In this presentation, I will discuss a method for expanding the design rules of the epi-seal process to include large lateral deflection structures, while still maintaining the desirable qualities of the original process. The method involves fusion bonding a sacrificial wafer to a silicon-on-insulator (SOI) wafer with devices already etched in it. The sacrificial wafer is thinned via grinding and polishing, similar to the fabrication of an SOI. Cavities are vented through the thinned wafer and devices released using HF vapor. Like the epi-seal process, the devices are then cleaned and sealed in the epitaxial silicon reactor. The resulting MEMS are fully encapsulated in single crystal silicon that is suitable for CMOS integration directly above the devices. Many widely varying devices were produced using this process in the Stanford Nanofabrication Facility (SNF) with high yield. I will discuss some of these devices and how we used them to characterize the package. -------------- next part -------------- An HTML attachment was scrubbed...

As most of you have observed there is a flurry of activity around the new tool area. A new bridge has been constructed, the new RTPs are mostly installed, power for the new FIJI is in , work on other facilities is moving ahead.We have had a small hang up with permitting(Stanford is building too many new buildings so the county is swamped). We are moving as quickly as we can to complete these projects. Thank you for your patience and understanding.

The last person who saw my mask is Linda Ohara, who kindly loaded my mask out of the SMIF box and put it in the lost and found bin in the gowning room last Thursday. However, it's already gone when I realized I lost the mask and checked the bin last Friday. I do notice there is a mask called "FINFET" in the lost and found bin. I'm wondering if you have mixed your mask with mine and took away the wrong mask. If so, please kindly check and change it back. I'll really appreciate your help.
