===== SignupMonkey + Wiki: Off-Campus Access=====
=====Focused Ion Beam (Raith Velion) - TOOL DOWN for Raith Service=====
Due to a DDoS attack affecting the Signupmonkey server, we have restricted access to the website, including both the Nanofab Wiki and Signupmonkey, except for users '''on campus using UCSB Wi-Fi or LAN'''.
Some users have experienced issues with column alignment when using Au ions. Raith service will be onsite today and tomrrow to make adjustments. I'll run checks and calibrations over the weekend. I expect the Raith Velion to be available again on Monday morning (Sept 16th). I'll send further updates if anything changes.


If you are off-campus, 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:

=====MLA150: UP=====
Optical AF has been calibrated and Defocus + Dose values are the same as before. PneuAF has not been checked et, but we expect a shift in PneuAF Defocus due to the Pneumatic nozzle replacement.

This is hopefully a temporary solution, we will implement other remedies next week.
=====Stepper #3 (ASML DUV) - Down, update=====
The alignment laser has now fully failed (no laser output at all), so we can't perform any exposures.
ASML engineers will be on site Monday Tues (Sept 16th) to perform the repair.

=====Suss SB6-8E=====
=====Unaxis Dep: DOWN=====
The computer is not coming up, after the campus-wide power outage last week. Will continue to work on it next week.
When the vendor came in to install the new top heater he wasn't able to get the z-axis (elevator motor) to move. He was able to install the new heater and do a PM on the rest of the tool. We are ordering a new z-axis controller on the recommendation of the vendor. If all goes well this should solve the issue and make the bonder fully operational. I'll send out an email once the new controller has been installed.

We finally got the slit valve assemble to seal correctly after making a number of mechanical adjustments. The tool is currently running an O2 clean and should be available to use within the next 10-15 minutes. Please let us know if you encounter any issues. The load lock seems like it's taking a while to get down to 0mT but that could just be a product of being open for the past several days.

The YES has been giving downstream temp warnings for the RF generator. These happen on the 3000W recipes that run for more than 4-5 minutes, and are just warnings (yellow banner/light), and can just be acknowledged without notifying Staff. Our other generator is out for repair, so this will be the norm until we get it back. Please let us know if you do get an error for this; red banner/light.

We are required to switch to new gowns in January. The new gowns won’t have pockets, but you are allowed to purchase cleanroom tool belts. Please ask staff for which tool belts you can purchase.

Two vendors for cleanroom belts we are using are listed here, you may request others:
* [https://www.terrauniversal.com/tool-belt-pocket-49in-waist-white-altessa-grid-uniform-technology-4954-60a.html Uniform Technology Tool Belt] - note the waist size, the 49” belt fits up to ~36-38” waist.

We found a blown resistor (and a questionable op amp) on one of the boards that contains the z-axis motor circuit. However, we still cannot get the tool to initialize. Next we will try swapping out the hard drive again and run some more tests.

I will send out an update once we have one.
