=====Lab is OPEN=====
=====Atomic Force Microscope (Dimension ICON) - 05/17: System UP=====
We completed our work early and the lab is now open for use.
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!

=====MA6 TSA is down - Update=====
=====Olympus DSX Microscope: Down=====
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.
Multiple attempts to unbind the Y axis motor have been unsuccessful. The motor may have failed so I am waiting to hear back on Suss about availability and lead time.

=====Stepper #3 (ASML DUV) - Maint moved to March 3rd=====
If you are in desperate need of using the tool with the topside microscope, CNSI's Quantum Structures Facility has one available for use:
We have postponed the Periodic Maintenance (PM) to the week of Monday March 3rd.
Please plan your work accordingly.

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

=====Velion FIB Tool DOWN=====
=====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.
Raith service are installing and aligning a new GaBiLi source. The Velion FIB column is not available to users until further notice.


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.
//[[User:Mehalana v|Vraj Mehalana]] 10:58, 30 April 2024 (PDT)


Please use the original tool name on SUM to make all future tool reservations.
⚫
=====Stepper #3 (ASML DUV) - Pneumatics repaired, extra day for optics=====
We were able to repair the pneumatics issue and are currently running reticle and wafer reproducability runs overnight to exercise/test the system.


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.
Consequently the optics was only started today, so will take one day longer than planned - we will extend this visit to Thursday to complete the work.


Please feel free to email me directly with any questions you may have.
Sorry for the inconvenience.


Thanks

=====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:
* [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.

=====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.
