We suspect it is LDD-26W. Can anyone else confirm this or tell us if they have successfully used Co and LDD-26W together in the same processing line? Additional chemicals that we use, and we haven't conclusively eliminated are xylenes KOH Acetone Methanol Acetone 1165 microposit remover Please also let me know if you have had problems with any of these and Co/Fe Thank you, Scott Andrews From mtang at snf.stanford.edu Tue Sep 9 11:36:14 2003 From: mtang at snf.stanford.edu (Mary Tang) Date: Tue, 09 Sep 2003 11:36:14 -0700 Subject: SNF Visitor Form Message-ID: <3F5E1D9E.264A15C9@snf.stanford.edu> Labmembers ? Recent events cause us to look more carefully at regulating access to the lab. We?ve had someone (a labmember who hadn?t ever worked in the lab) bring his kid in for a tour. We?ve had someone bring in contractors who were building THEIR lab ? generally not a problem, except that they began moving tables and equipment around and just plain getting in everyone?s way. We?ve had some people bring in their non-SNF labmates to do processing (and now this is NOT acceptable.) Such unregulated visits can be disruptive. Most importantly, they present very serious safety and liability concerns... So, I?d like to take this moment to clarify our visitor policy. 1. Only staff, labmembers, and sponsored contractors should be able to enter and leave the lab at will. Anyone else must be escorted. 2. Visitors may enter the lab if escorted by staff. 3. A visitor may enter the lab escorted by a labmember if an SNF Visitor Form is completely filled out, and submitted. These forms are now available outside the gowning room, next to the white board. Please use these forms for your visitors. And please help us and your fellow labmembers by keeping an eye out for strangers in the lab (?constant vigilance!? as Mad Eye Moody says.)

(in my case, with lithium niobate z-cut wafer and want to protect the -z face) Gold or tantalum coating would work for sure, but I thought there might be a much easier and faster way. I had tried Apiezon 40 wax, by solving it in leksol and then applying it to the surface with cotton tips. Under microscope, the wax left over the wafer seemed porous on the surface and not uniform after the evaporation of leksol. This kind of wax layer would totally peel off after half an hour of etching, which meant the wax did not attach to the wafer very well, although it seemed to be working before it was peeled off. But repeating the wax-applying before it peels off is for sure a painful thing to do when working with HF. High-temprature applying has not tried yet and I'm worrying about a similiar behaviour as the other way. A spin-on way has not been tried yet since the leksol solution of wax has very fast evaporation (in seconds) and dirty left over. Had anyone else tried this kind of experiments? Any suggestions very be appreciated a lot!

Message-ID: <3F673E3D.7010605@snf.stanford.edu> SNF Lab Members: Jeff Allen from Nanonex will be speaking at a special seminar THIS AFTERNOON (Tuesday, September 16) at 4:15 p.m. in the CIS-X Auditorium. As you may know, Nanonex (www.nanonex.com) manufactures nanoimprint lithography tools and has demonstrated 10 nm feature sizes. You are invited to attend this special seminar and to hopefully learn more about nanoimprint lithography in general and the offering of Nanonex in particular.

Message-ID: <3F674412.5080301@snf.stanford.edu> SNF Lab Members: Several of you have discovered a problem running Remote Coral on a machine that is running the latest version of Java known as JDK 1.4.2. The symptom of the problem is that when Java Web Start is trying to download the Remote Coral application, a window will pop up that is entitled "Security Warning" and will include the message: "Warning: Failed to verify the authenticity of this certificate because there was an error parsing the certificate. No assertions can be made of the origin or validity of the code. Installing and running this code is not allowed." This window only has an "Exit" button ... and if you click the "Exit", the download will stop and Remote Coral won't start. If, however, you simply close that "Security Warning" window (by clicking the "X" in the upper right hand corner of windows machines), the dowload will complete and Remote Coral will run. While this is not the perrmanent or proper solution to this problem, this appears to work as an interim measure. In the meantime, the Java Web Start development team at Sun is working with the folks at Bouncy Castle (the encryption package that we use in Remote Coral and the authors of the jar file that is triggering this security warning) to find out why the latest version of Java is having troubles with the Bouncy Castle signed jar files ... that are signed with a certificate that is, in turn, signed by Sun. Hopefully, this problem will be properly and fully resolved in the near future.

Message-ID: <3F71CE80.2090207@snf.stanford.edu> SNF Lab Members: A number of you have reported a variety of problems with the aging version of netscape in the lab. In an effort to circumvent these problems, we've installed Mozilla version 1.2.1 on the sunrays in the lab. Mozilla is, I think, the open source spin-off of Netscape. I believe, however, that this version of Mozilla will address many of the problems that have been reported by netscape users. You can start up Mozilla by typing "mozilla" to the command line (or "mozilla &" to run it in the background which will free that command-line window for other activities). The first time that it starts up, it will ask if you want to convert your netscape profile ... if you do, this should convert your old netscape bookmarks and make them availabe in mozilla. Particularly if you are one of the folks who had experienced problems with netscape, please let me know it this version of mozilla circumvents these problems. Happy browsing, John p.s. If this version meets most people's needs we will likely de-commission netscape completely and see if the "world clock" icon on the task bar can be switched to fire up mozilla. From mtang at snf.stanford.edu Fri Sep 26 11:05:04 2003 From: mtang at snf.stanford.edu (Mary Tang) Date: Fri, 26 Sep 2003 11:05:04 -0700 Subject: Missing Gold Message-ID: <3F747FD0.5EBB53F4@snf.stanford.edu> Labmembers: I?d like a moment of your time, and possibly your help. Recently, a gold target for metallica was taken from a staff member?s desk drawer. As the target was packaged in a plastic case and then covered in unlabeled bubble-wrap, it?s likely that it was taken by someone who recognized it for what it was. The value of the target is over $900. The actual loss of the target is less of a concern for us than the fact that this office is normally locked and it was clear that the staff member?s desk has been searched (this target had not been placed where common targets are normally kept). This is disturbing because not only is it a breach of good manners to invade someone?s personal property in this way, but it is also a breach of Stanford honor policy ? and it appears that the violator is very likely one of our own labmembers. There have been several incidents in recent history in which technical instrumentation or lab materials have gone missing and theft was suspected. In each case, the problem was found to be due to miscommunication or misunderstanding, NOT theft. I sincerely hope that this is also true here. We are presuming for now that the missing target was taken by someone who thought it was theirs or desperately needed it off-shift. If so, we ask that it be returned in whatever state, no questions asked (although an apology might be appreciated). This would, at least, reaffirm my belief that in the honor system that is basis of our lab community. Please, if any of you have any idea of who this person might be, a firm reminder to them of his/her obligation to the lab community would be appreciated. Mary -- Mary X.

Message-ID: <3F74898E.7090908@snf.stanford.edu> SNF Lab Members: As you may know, the university has changed it's entire accounting system effective September 1, 2003. One of the side effects is that the 7-character account numbers (1ABC123, 9VAV456, etc.) are now being replaced by three fields called Project, Task, and Award. In Coral, new account numbers will look like hyphen-separated Project-Task-Award fields such as 1067248-215-EKFHK. Because these new numbers will not be terribly easy to identify or remember, we will begin to use the Coral Project field (that has no relation to the university-wide project in Project-Task-Award) and a more meaningful "alias" for this Project-Task-Award number. This is similar to the way that many of us think of "My Mastercard" without really remembering all 16 digits, plus expiration, plus the funny digits on the back. For most industrial users, who typically charge to only one account, your new project name will be your company name (minus, any "Inc.", "Corp.", "Ltd." ...). For non-Stanford academic folks, you will likely see a progject that includes an indication of both the institution and your advisor such as: "UC Berkeley (tking)". Each of these projects will be linked to the proper new account number. For Stanford folks, we have asked each PI to provide us with a name that is, hopefully, meaningful to them and to you. To make sure that this name is unique, we will affix the PI's name in parenthesis at the end. So, a valid university project might look like "Optical devices (yamamoto)" or "NSF Microfluidics (tkenny)". Many, but not all, of the Stanford PIs have provided us with this information. This database conversion will be taking place over the weekend. It requires extensive changes as we have to add all of these projects and accounts, associate each user with the proper new projects and accounts, close all "old style" projects and accounts, and convert all activities that have occurred since September 1 to these new projects and accounts. While much of this can be done "behind the scenes", at some point we will have to stop Coral, make the final cutover, and bring Coral back up using all of the new projects and accounts. Unfortunately, I can't yet predict exactly when that will take place but will do my best to: keep the downtime to a minimum and to give you some advance warning. There will likely be some cases, once the conversion takes place, where people will be unable to fire up Coral because they do not have a new project and account. In most cases, this will affect Stanford students if your advisor has not provided us with a complete list of project names and assignments. If this happens to you, send e-mail to us (coral at snf.stanford.edu) and we will do our best to resolve these cases as quickly as posible.
