From degtz at stanford.edu Tue Jun 5 22:26:20 2007 From: degtz at stanford.edu (David Gutierrez) Date: Tue, 5 Jun 2007 22:26:20 -0700 Subject: use of polystyrene nanospheres in SNF Message-ID: I am emailing in regards to a proposed material that we plan to bring into SNF during the summer. Part of the project that we will be working on will involve the use of polystyrene nanospheres for use during one of the process steps. My group members and I are wondering whether this material can be allowed to be brought into SNF. I am attaching the MSDS provided by the company (Duke Scientific) that describes the material. These polystyrine nanospheres come in 15ml containers and are in a water solution. The individual polystyrene nanospheres will be in the range of about 300-500nm for the purposes that we are trying to use. This project will be part of E342: MEMS Fabrication for the summer quarter. Please contact us at your earliest convenience to determine whether we can proceed with the proposed plan, or if we have to find alternate solutions. Regards, David E.

The SpecMat committee and I will have to see your proposed process flow before a decision can be made. The process flow should include all of your process steps and the requested equipment.

Yes, we are planning to bring BCB (Cyclotene 3022-57), adhesion promoter AP3000 and Primary Stripper A from Dow CHemicals. I e-mailed Dow to request the MSDS and will forward their e-mail to you as soon as I get it. Process flow: - spin AP3000, BCB on headway - softbake - cure in bluem - use of PR or SiO2/SiNx as mask (mask is of course patterned using optical lithography) - etch of BCB in O2/CF4 plasma (either Drytek4 or PQuest after 21st of each month for GaAs users) Please let me know if you need any additional information.

Will we be able to bring our wafers from Tom Carver BACK INTO THE SNF once he has deposited the metal layer? If this is a problem, could we gain litho-only access for processing those wafers that we bring back into SNF? Or do we need to figure out a way to finish our processing outside of the SNF?

Jeanine is not very comfortable with this when I talked with her a few weeks ago. At the time, she was concerned about how the system was functioning. Jim has worked on the tool and the performance is much better, although we have some Low Frequency oxide problems. My understanding is, low temperature depositions have been done in the past. I do not know if there was any problems or is this is something we should be able to support when requested. The users are anxious to test the process. I would like to give them a quick response. Jeanine is on vacation, so we tneed to make the decision without her knowledge.

You can put more dep onto the walls of the reactor without it flaking off if you keep it at a constant temperature. It is a thin film stress issue. If you are willing to live with more particles or to do a chamber clean, there is no big problem lowing the temperature. You will see a decease in dep rate at lower temp. I some process data from a similar Plasmatherm PECVD system. For both oxide and nitride, they give a dep temp range of 350 to 100C.

The low temperature does not appear to cause a problem with the equipment, but can have process problems, especially particles. As a result, your group will be responsible to take all actions required to minimized potential particles for subsequent users. This means, the chamber must be cleaned following your low temperature depositions (If particles are a problem for your process, you will need to lower the chamber temperature, let it stabilize, clean and coat the chamber before your deposition). Following your low temperature deposition you must do the following before returning the system back to the user community. 1) do a chamber etch to remove any and all depositions on the chamber (the chamber temperature during the etch is not critical as long as all depositions have been removed) 2) Chamber coat per standard procedure. The chamber must be at the standard temperature and equilibrated before the chamber coatings can start and the films and film thickness must be per specification.
