Thanks for all the responses. I summarized the information I received. I hope it will be helpful if someone else need it as well.

cheers,

sierra proto express (http://www.protoexpress.com/) is local (sunnyvale) but can be expensive

imagineering (http://pcbnet.com) is in illinois but they are the least expensive that i have found, especially if you panelize. i have an active order with them right now, 3 day turnaround and 2 day shipping.

Try http://www.infinitisolutions.com/emsservices.html
They have a local quick turn service.

They're not local, but Circuit Express (http://www.circuitexpress.com/) can get you a quick turn-around time.

If one week is ok, you can go with some Chinese companies for rather low price.
I use this one a few months ago. <$100 for ~50 pieces and delivered within a week.

office (RM 145). PLease come along and buy some goodies and know that your 
generous donation will be going to a great cause.

As you may know this cause means alot to me as I have lost good friends to
cancer and seen survivors suffer from this terrible disease. Deep down I am 
sure we all know of someone who has been affected. So, lets help make a
difference.

If your unable to come to the bake sale and would like to donate then go online 
to my personal fundraising page.

Subject: Zeta-20 Three Day, 3D Imaging Demo at SNF
Message-ID: <6.2.5.6.2.20090910090916.034f19d8@stanford.edu>

Stanford Nanofabrication Lab Members,

Zeta Instruments and SNF is happy to announce a 
three day, on-site demo of the Zeta-20 next week, 
Monday Sept. 14th through Wednesday Sept. 16th.

The demo schedule plan is as follows:

Monday, Sept. 14. We will arrive around 10:30 am 
to have the system ready and start the demos around 1pm.
Tuesday, Sept. 15. Demo from 9 to 5.
Wednesday, Sept. 16. Demo from 9 to 4. 
Afterwards, we will pack up the system. However, 
if there are more samples to run, we can run them at our facility in San Jose.

The Zeta-20 is a cost effective 3D imaging and metrology microscope.

Some of the key measurement capabilities are:
?     Very low reflectivity samples
?    High roughness samples (e.g. too rough for AFM to measure)
?    Sub-micron to millimeters of vertical range
?    True color 3D images

[]


The Zeta-20 scans your samples in Z direction and 
creates a composite image. It is a low cost yet 
powerful 3D imaging and metrology system. The 
Zeta-10 upgrade package  is an alternative to the 
stand-alone Zeta-20. It converts your existing 2D 
microscope into a 3D metrology system. The Zeta 
systems are based on non-confocal optical technology.

We look forward to seeing you. For inquiries 
about the Zeta products, please contact:

CNF PIs and Users

Once again, NNIN will conduct an International Winter School for Graduate
Students, this year in Mumbai at  IIT-Bombay,  Nov 30-Dec 13, 2009. Travel
will begin on Friday Nov. 27.  This year's topic will be Nanoelectronics.
This follows last years inaugural offering on Organic Electronics and
Optoelectronics held at IIT-Kanpur.

The School will consist on an intense technical course on Nanoelectronics at
the graduate level--a one semester course taught over an intense 6 days. The
course will be taught by leading faculty from US and Indian institutions.
Approximately 10 outstanding graduate students from across the US will be
chosen to participate. They will be joined by 50 or more students and
faculty from India.

After the technical course, the US and Indian participants will participate
in a field experience for 4 or 5 days in an Indian village, working with a
local NGO.

We encourage applications from serious, adventurous, advanced graduate
students with an interest in Nanoelectronics, in the international aspects
of scientific research, and in the impact of science and technology on the
3d world.

Participants DO NOT have to be from NNIN institutions and DO NOT have to be
NNIN users. We encourage all outstanding graduate students ( US citizens and
permanent residents only) to apply. Travel expenses will be paid by NNIN.

Application information is available at
http://www.nnin.org/nnin_iwsg_2009.html .

The application deadline is September 14, 2009.

Postdoctoral Position
Institute of Neuroscience
University of Oregon

Project title: Microfluidic devices for electro- and 
optophysiological screening and analysis of new anthelmintics.

Description.  There is an urgent and continuing need for new 
anti-nematode drugs, known as anthelmintics.  Anthelmintic drug 
discovery efforts have not kept pace with emergence of 
anthelmintic-resistant strains in humans and economically important 
livestock.  This problem arises because resource-limited countries do 
not support markets that can offset the enormous cost of drug 
development, estimated to be on the order of $800 million per drug. 
Anthelmintic screening strategies have not changed significantly in 
almost 50 years.  The proposed research addresses this problem by 
combining microfluidics and electro- and optophysiology to screen 
drug candidates and identify their biological targets simultaneously. 
We currently have proof-of-concept for microfluidic devices that 
allow one to record changes physiological activity in nematodes upon 
delivery of candidate anthelmintics.  The main activities of this 
position will be (1) to scale these systems up to tens to hundreds of 
simultaneous recordings, (2) to develop automated data analysis 
strategies for interpreting the effects of candidate drugs, and (3) 
to demonstrate the practical utility of these novel systems.

Degree. PhD in engineering (bio-, electrical, mechanical, or chemical).

Qualifications.  The main qualifications are a track record of 
inventiveness and out-of-the box thinking in the design, 
construction, and testing of novel devices.  Prior experience in 
microfabrication (esp. soft lithography and/or bio-MEMS), optics, 
time-series data analysis, and/or image processing would be 
considered a plus.

Funding.  The project is funded by the National Institutes of Health 
via the American Reinvestment and Recovery Act (ARRA).  Support is 
guaranteed for two years with the possibility of longer term funding 
as the project advances, including commercial ventures.

Starting date.  In keeping with the spirit of the ARRA, the position 
is available immediately, but the goal is to fill the position by 15 
January 2010.

Contact.  Dr. Shawn R. Lockery, Associate Director, Institute of 
Neuroscience, 1254 University of Oregon, Eugene, OR, USA.  E-mail:

Silicon-based photonic crystal light sources
Maria Makarova
Advisor: Prof. Jelena Vuckovic

Time: ?Thursday, October 1st, 10:00 am (refreshments at 9:45)
Location: ?CIS-X Auditorium

Abstract:

Efficient light generation on silicon is desirable for a variety of
applications because of its low fabrication cost relative to III/V
semiconductors and because it will enable monolithic integration with
electronic components on the same Si platform. ?We studied
silicon-rich silicon nitride with emission in the visible and
erbium-doped silicon nitride (Er:SiNx) with emission at 1540 nm. ?Both
of these materials are compatible with the mainstream complementary
metal-oxide semiconductor (CMOS) processing technology. In this talk,
I will discuss our results on using photonic crystal (PC) cavities to
enhance luminescence from these materials. Nano-resonators modify the
local optical density of states (DOS) to enhance the emission in a
fundamentally different way than what is accessible through materials
engineering. Specifically, photon emission rate can be enhanced at a
particular wavelength because the optical DOS is higher at the cavity
resonance, which in turn improves efficiency and allows faster
modulation rates. ?We have demonstrated up to 11-fold enhancement at
photonic crystal resonance relative to smooth film at 730 nm and
30-fold enhancement at 1540 nm. ?Most recently, we have observed
cavity line-width narrowing with increasing pump power in the
erbium-doped sample, resulting from decrease in ground-state
absorption by erbium ions as more of them are excited. ?We achieved
excitation of up to 28% of Er ions at cryogenic temperature. ? This is
an important step toward realizing a laser based on Er:SiNx in the
future.

Title: Wafer level thin-film encapsulation for RF MEMS resonators and  
filters.
Advisor: Prof. Thomas W. Kenny, Prof. Roger T. Howe

Time:  September 30, 2009, 2:00 pm (Refreshment served at 1:45pm)
Location: Mechanical Engineering Research Lab (MERL), Conference room  
(2nd floor, by the kitchen area)
Campus map: http://campus-map.stanford.edu/index.cfm?ID=02-660

Abstract:
RF MEMS devices are becoming an promising alternatives for components  
in radio systems due to its high-Q, size, and on-chip compatibility.  
However, packaging for RF MEMS devices still remains a big challenge  
for commercialization. Using epitaxial silicon thin-film to  
encapsulate MEMS devices has been shown as a robust packaging  
technology, however the frequencies of devices were not yet in the  
radio frequency ranges. This talk will first evaluate the signal  
characteristics of silicon packaging followed by the presentation of  
two innovative packaging methods optimized for RF resonators and  
filters. The performances and models of resonators and filters  
packaged using these methods will also be presented.

Best,

Dear labmembers,

I am designing some suspended structures (something like the membranes of pressure sensors) on silicon wafer but feel myself bogged down by the fab process. I will very appreciate if anyone who has experience in (or is currently doing) back-side litho/etching could offer me a couple of minutes to give some hints on the process details.

Thanks a lot,

Message-ID: <4AC294A8.8080804@stanford.edu>

Dear labmembers --


We're trying to install a lamp on the low power stereo microscope (also 
called a "dissecting" scope) in the lab.  However, it is missing the 
large screw ring that fits around the objectives.  This would be handy 
for attaching the lamp.  This ring was observed to be on the scope just 
a few days ago.  If you have this or have seen it, please return to the 
scope so we can upgrade it. 


Thanks,

Mary

Subject: The door between the gowning room and the cleanroom ....
Message-ID: <4AC2C5B8.1020706@stanford.edu>

SNF Lab Members:

As a number of you know, the inner door between the gowning room and the 
cleanroon was not working much of today and folks were manually sliding 
it open and shut.  Even that doesn't seem to work any longer.

As a result, we've opened it completely and turned off the power to it 
so that it will stay open.  We have also defeated the "Door Closed" 
sensor so that it thinks that the inner door is closed .... so that the 
door to the hallway will open and close normally.

While this is not ideal from a cleanliness perspective, it is better 
than people having trouble accessing the lab .... either entering or 
exiting ... and better than having people get frustrated and jam something.

Hopefully, the service organization that works on this will be here in 
the morning to fix this properly.

Thank you for your patience and continued support,

John

Title: Microstructured Adhesives for Climbing Applications
Advisor: Prof. Mark Cutkosky

Time:  Oct. 2nd, 2009, 2:30 pm (Refreshment served at 2:15pm)
Location: Mechanical Engineering Research Lab (MERL), Conference room (2nd floor, by the kitchen area) 
Campus map: http://campus-map.stanford.edu/index.cfm?ID=02-660

Abstract:
Researchers seeking to expand the capabilities of mobile robots have begun looking to biological systems for inspiration. One particularly agile creature, the gecko lizard, is remarkably adept at maneuvering across both flat and vertical surfaces. Some species of gecko are even capable of climbing across inverted surfaces. The study of the gecko's adhesive system has informed the design of several synthetic adhesives in recent years. However, these adhesives generally fail to match the gecko adhesive's performance in one fashion or another. Many previous synthetic gecko adhesives are not reusable or they lack a method of control. Others do not have the ability to conform to surfaces with any roughness, or to distribute forces across the many thousands of fibers evenly. This presentation focuses on the design of a gecko-like adhesive system that achieves the level of performance necessary for implementation on a small-scale climbing robot.

A gecko's adhesive structure has a strong directional preference, allowing the animal a method to control the stickiness of its feet. When loaded from the tip of the toe towards the palm, the material exhibits high adhesion in both the shear and normal direction. However, when this load is released, or when the toe is loaded in a different direction, no adhesion is present. First, I will discuss the creation of a synthetic micro-structure that also displays a directional adhesive dependence. This begins with the presentation of a new lithographic process used to create asymmetric wedge-shaped cavities in a photo-sensitive epoxy at the scale of tens of microns. Elastomeric materials were cast into these molds to produce the synthetic micro structures. Analysis and laboratory testing of this material show its strong directional dependence. Its performance for robotic climbing applications was promising at small sample sizes when tested on smooth surfaces like glass. However, the material proved inadequate for climbing because its performance could not be scaled to areas greater than about 1 cm2, nor could it adhere to rough surfaces.

The gecko uses a multi-tiered hierarchy to insure that its millions of sub-micron sized spatulae make intimate contact with a surface regardless of its roughness. The gecko's system conforms across multiple length scales, distributing climbing forces and allowing rapid locomotion with seemingly minimal control effort. In the second portion of the talk, hierarchical suspensions for fibrillar adhesives are analyzed, and three iterations of a synthetic hierarchical adhesive design are detailed. The use of these hierarchical suspensions with modified wedge micro-structures similar to those mentioned above turned out to be successful enough to allow a mobile robot platform named Stickybot to climb multiple vertical surfaces ranging in roughness from glass to drywall. Data from large patches, well over 100 cm2, are also included. Discussion of these results and their implications for human climbing applications will conclude the presentation.
