===== Raith EBL Update =====
Raith replaced every item that was left to replace in the column on Monday. Yesterday they performed some quick tests @ 50kV and the issue with deflector settling was gone. This is an extremely positive result! It almost certainly suggests that the issue has been repaired. However, tests @ 100 kV remain to confirm the behavior and we are doing so later today and early tomorrow morning.


===== EVG is down - Update=====
I am pretty confident that we are going to have a fully functional EBL system available for use early next week!
I checked in with our vendor today as it has been 2 weeks since they got started on our RF generator. They are waiting on a part for it that should be arriving on Monday. If all goes well we should have the unit back late next week. I'll check with the vendor again on Wednesday and send out another update.

===== E- Beam #2 Maint Work Next Week=====
E-Beam #2 will be down next Wednesday (10/16) and possibly into Thursday to replace the hoist sensors. This will also reduce the likelihood of future issues with the hoist which we dealt with recently. I will send an email out once the work is completed.

=====Stepper #3 (ASML DUV) - Tool UP=====
// [[User:John_d|Demis D. John]] 20:08, 22 April 2025 (UTC)
I have recalibrated the system focus, system is ready for use, back to your *normal* focus offsets. No need to run and add IQC.

Please do let me know if you see IQC focus is out of the ±50nm spec again - it was intermittent for a while. I believe particulate contamination was the cause (from the last system repair).

Reminder to be *extremely* careful to clean the underside of your wafers and ensure not particles are on the Chrome side of your photomask! Let me know if you see any problems with users following these cleaning procedures, or if you have questions/need a refresher on this. // [[User:John_d|Demis D. John]] 00:39, 22 October 2024 (UTC)


=====Suss SB6-8E=====
=====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.
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.


I will send out an update once we have one.
