=====Dry Etch, Si Deep RIE (PlasmaTherm DSEIII) - IMPORTANT: Please Read!=====
=====DSE is UP=====
We will be taking down the DSE to changeout the turbo pump next Wednesday (5/28). If all goes well the tool should only be down for the day. I’ll keep you updated with emails.
I’ve completed the installation of the new spool and lamps and the tool is free to use. We’ve run a number of different etches and upon initial inspection everything looks normal. However, it’s recommended you start with a test etch in case there is a slight shift in process.

* [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.
Optical AF has been calibrated and Defocus + Dose values are the same as before. PneuAF has not been checked et, but we expect a shift in PneuAF Defocus due to the Pneumatic nozzle replacement.

=====Stepper #3 (ASML DUV) - Down, update=====
The alignment laser has now fully failed (no laser output at all), so we can't perform any exposures.
ASML engineers will be on site Monday Tues (Sept 16th) to perform the repair.

=====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.

Bell jar mount is in place. Hoist has been tested several times. System is ready to use.

=====YES is available=====
The error has been cleared and I ran a shorter 5 minute recipe with no warning/error.

This seems to be exclusive to the longer (8+ minute recipes), which are throwing warnings for every wafer run this long. It also appears that running 3 wafers on a longer recipe will result in an error and aborted run on the 3rd wafer. We are just going to have to live with this until we have our other generator back. So until then, please limit the longer runs to 2 wafers max. If you have more than 2 wafers to run on a longer recipe then wait about 5-10 minutes in between batches.
