Stepper #3 (ASML DUV) - Tool down
Wafer stage positioning laser is dying, Asml engineers will be on site Monday and Tuesday to repair. We have the replacement already on hand.
Unfortunately, we cannot initialize the stage at this time. System is down. // Vraj Mehalana 18:36, 3 October 2024 (PDT)
MLA Service Complete
The FSE has completed their work.
I ran beam offset checks on both lasers prior to the maintenance and found that the Y axis value for the 405 laser was off by ~0.6 µm. I made the necessary change and ran another check with all values in spec. I also ran beam offset checks on both laser post maintenance along with an overlay exposure and all looked good.
Tool is available to use.

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.
