DSE is Down

After installing our backup spool the system ran for approximately 15 minutes and then failed again due to a leak in the chamber. I took apart the chamber and found a crack on the backup spool.

I spoke to an engineer at PlasmaTherm and he told me this issue was indicative of a failing lamp (or lamps) that was causing a large delta of heat across the ceramic spool.

I requested to have a couple new spools to be overnighted but they most likely won’t ship out until Monday. I tested the lamps and found two that were pretty heavily oxidized on the leads.

I’ll install all new lamps and the new spool when it gets in next week.

IBD is UP

Replaced bad PLC controller on Depo beam. I then tested the beam with a 15 min gridclean recipe without issue. I then ran an SiO2 dep, and a 1 hour gridclean without issue.

MLA150: UP

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. // Demis D. John 18:14, 11 September 2024 (PDT)

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. // Demis D. John 18:14, 11 September 2024 (PDT)

Suss SB6-8E

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.

YES EcoClean UP

The YES has been giving downstream temp warnings for the RF generator. These happen on the 3000W recipes that run for more than 4-5 minutes, and are just warnings (yellow banner/light), and can just be acknowledged without notifying Staff. Our other generator is out for repair, so this will be the norm until we get it back. Please let us know if you do get an error for this; red banner/light. // Demis D.
