We determined that another manipulator is broken. The part has been identified and we will begin the replacement process shortly. There are 3 remaining manipulators. Please be careful, or we will all be reduced to doing diode measurements. =) Do not pull the broken manipulators out and attempt to use them for 4-point measurements. The problem is in the contact, so you will probably not be getting accurate results. - Mihir From dejia at stanford.edu Wed May 16 18:48:13 2007 From: dejia at stanford.edu (Deji A.)

What needs to be done to avoid breaking > the manipulator? Good question. Sorry I wasn't more clear. In this case, we determined that the issue is a wear-and-tear problem. Older users might recall that the Cascade used to have a shared set of probe tips - but due to frequent damage, each user was required to provide his/her own probe tips. So each user removes/inserts probe tips during their session. It is this continuous action that wears down the contacts inside the manipulator. There really isn't a way around this. We can return to a common set of probe tips to minimize wear, but that will result in damaged probe tips from careless users. Around and around we go... One thing that would help - from all users - is making sure that the stage and manipulators are clean *before and after* your session. Use wipes with a little bit of IPA to clean the surface and bottoms of the manipulators. This prevents vacuum problems. - Mihir From dejia at stanford.edu Wed May 16 21:57:19 2007 From: dejia at stanford.edu (Deji A.)
