=====EBeam4 Update - Still down=====
=====Lab is OPEN=====
We completed our work early and the lab is now open for use.
EBeam4 will remain down overnight.
-- Tony


//[[User:John_d|Demis D. John]] 22:23, 10 February 2025 (UTC)
The new motor arrived as well as the new junction box and new cables.


⚫
=====Olympus DSX Microscope: Down=====
I removed the old junction box/plugs due to a lot of corrosion inside the box caused by it being located directly under the water supply lines.
After speaking with Olympus it looks like there is a problem with the polarizer that is interfering with basic system initialization. I'm waiting for the repair quote and will update everyone when we know more.

=====Stepper #3 (ASML DUV) - Maint moved to March 3rd=====
This corrosion inside the box could have contributed to the failure of the old motor.
We have postponed the Periodic Maintenance (PM) to the week of Monday March 3rd.
Please plan your work accordingly.

=====ICP #2 Maint: Complete=====
I installed the new motor, ran all new cables to the new junction box in it's new location away from the water lines.


The maintenance is completed and the tool is finishing up an O2 clean run. We are still seeing a 0.04-0.05 Pa actual pressure difference in the software (as before the maint work) which we will address tomorrow, as the tool needs time to reach base pressure. -- Lee Sawyer
I was able to test the function of the hoist by raising and lowering the bell jar while in manual mode.


//[[User:John_d|Demis D. John]] 02:01, 5 February 2025 (UTC)
For safety reasons, I had the machine powered off during the duration of the work being done, so the cryo will be in regen overnight.


=====Oxford ALD+Ion Mill: UP=====
Tomorrow morning I will continue testing the system to ensure everything is working properly before I release the tool.
The tool is useable and in its original condition. If you had a reservation under the previous tool designation it has already been moved over for you.


Chamber 1 is operational and available for use. However, only recipes that run at 300C are to be ran on the tool, as the current thermocouple is only calibrated for that temperature at this time.
I will send another email when an update is available.


Please use the original tool name on SUM to make all future tool reservations.
//10:36, 30 May 2024 (PDT)


There is no longer a need for supplemental training. If you have been previously trained on the tool but not received the supplemental training, you can once again reserve and use the tool.
⚫
=====Stepper #3 (ASML DUV) - System UP and calibrated=====
We have finished calibrations,
System is up.


Please feel free to email me directly with any questions you may have.
Reminder to check/recalibrate your exposure dose. Focus should be the same, but beam optics changeout will affect dose.

=====New Gowns: Toolbelts purchases=====
The chiller has a decent sized ball of ice inside of it.
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:
I need to let that melt off before I can do a proper diagnosis of what is causing the high pressure cut off to trip when the refrigerant pressures seem normal.

=====Suss SB6-8E=====
=====Atomic Force Microscope (Dimension ICON) - 05/17: System UP=====
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.
Head was repaired and returned today. A quick test showed correct performance. Note also that the pin board has been repaired so all 4 pins are now present. Lets keep it that way so please be careful when loading the tip holder!


I will send out an update once we have one.

Oxford ALD+Ion Mill: UP

The tool is useable and in its original condition. If you had a reservation under the previous tool designation it has already been moved over for you.

Chamber 1 is operational and available for use. However, only recipes that run at 300C are to be ran on the tool, as the current thermocouple is only calibrated for that temperature at this time.

Please use the original tool name on SUM to make all future tool reservations.

There is no longer a need for supplemental training. If you have been previously trained on the tool but not received the supplemental training, you can once again reserve and use the tool.

Please feel free to email me directly with any questions you may have.
