=====Fluorine ICP: UP=====
=====Raith Velion DOWN=====
We are experiencing issues with the 'imaging supply unit' on the Velion FIB. Raith service personnel are currently troubleshooting the problem.
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 fab is open but the following equipment still has lingering issues:

# Unaxis ICP-PECVD - Main computer is not coming up
# ALD/CAIBE - All chambers down. Bill is still working on it.
# Fluorine Etcher - Will remain down until it can be addressed Monday.
# EB3 - Cryo regen failed, on second regen so should come up later.
# GCA Autostep - Having computer issues.
# The ALD/CABE and EB3 have a more than fair chance of coming back up today.

Bill will have those updates along with the status of the Autostep.

Best,
I have reinstalled the generator and tested the tool without issue. Only time will tell if this latest round of repairs truly resolved the issue with this generator losing power intermittently.

=====EVG - Scheduled downtime=====
I am looking at sending that generator on the week of the 24th or 31st. It should not take that long, but I would plan for it to be down for 3 weeks.

Please let me know if this does not work for you or if you prefer one week over the other.

Raith service have replaced the interferometer laser, and the system is pumping down overnight. I'll run calibrations and checks tomorrow and expect the Velion to be open for general use on Wednesday morning.

New Gowns: Toolbelts purchases

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:

Suss SB6-8E

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. -Aidan // Demis D. John 00:35, 8 December 2024 (UTC)

ICP1 Down

The board we were waiting on arrived, but it did not resolve the tool issue. We are working with Panasonic on the next steps. //Vraj Mehalana 14:17, 1 March 2024 (PST)
