===== Raith EBL Update =====
Unfortunately the fix discussed in the last update turned out to be a good news/bad news thing. The good news is that the majority of the field distortion problem we have experienced since the install has been addressed. However the bad news is that there is still a residual settling effect that is distorting the field in one part of the field only and prevents the tool from fully meeting specifications. So it turned out to a layers of an onion kind of thing – because of course it did.


So the suspect now is the fine focus coil in the column (one of the factory engineers predicted stitch shifts when a faulty fine focus coil is present which essentially replicated the errors we are now seeing) and the question now is how to get one of these sent to UCSB. They are a factory install item so for us to get one, and one that has been tested and confirmed to be fully operational, would require it to be taken from a tool currently under fabrication on the production line.
=====Dicing Saw (ADT) Upgrade 10/9=====
The dicing saw is scheduled go down for an upgrade on Monday October 9th and will be down for that week and into the weekend. Part of the upgrade will be updated software and will require users to be re-trained. I will provide more info on the re-training once I get a little hands on time with the updated software.
I'll send out a couple of reminder emails between now and then and keep everyone updated in the event the schedule for this changes.

We are close, very close, but still not quite there. And I am really sorry that is still the case…

If you are off-campus and experiencing issues, please utilize the UCSB VPN to access our sites. Here are the installation instructions for VPN on your device. You will need your UCSB NetID for download and installation - you would have received a UCSB NetID when you started using the NanoFab:
=====Plasma Activation (EVG 810)=====

We have received almost all the replacement parts for the tool except the new chuck. The original delivery date of mid June has now been pushed out to early September and they have stated that this is the best that their supplier can do. I will not be installing any new parts on the tool until we have everything.

Runs will still require Staff supervision until then.

However the bad news is that there is still a residual settling effect that is distorting the field in one part of the field only and prevents the tool from fully meeting specifications. So it turned out to a layers of an onion kind of thing – because of course it did.
