===== 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.


=====ASML: intermittent alignment failures=====
I am pretty confident that we are going to have a fully functional EBL system available for use early next week!
I have determined that the laser used for Alignment is failing, the power is low and it flickers.

=====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.

=====EBeam#2: Down=====
Good news is we have repaired and reinstalled the hoist, thanks Mike B. and Bill. I have tested it and everything looks good.

However, the repaired bell jar mount is not sliding down the hoist pole like it should. Since the repair involved some welding to the collar that slides down the hoist pole, we surmise that the concentricity was affected by the heat. The mount is back at the machine shop getting honed out. I should have it back to test late today/early tomorrow but it may have to go back again. Once it is able to slide on properly the tool should be up shortly thereafter.

=====YES EcoClean: 3kW only=====
I swapped out the RF generator and the tool is working again. I am getting repeated CCP warnings for the 0.7kW recipes so we will need to look into that further.

System is up for 3kW recipes only.

DO NOT run 0.7kW recipes until further notice!!
