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.

We have added a timer that interlocks the lamp power supply since some users seem to have a problem remembering to turn the tool off when finished with it. The minimum time it can be set for is 30 minutes and the max is 4 hours. You will no longer be operating the main breaker on the front of the power supply. I have updated the SOP to reflect the changes, there is a copy at the tool and on [https://wiki.nanofab.ucsb.edu/wiki/DUV_Flood_Expose#Documentation:~:text=Exposure%20System%20Spectra-,Documentation,-%5Bedit%20%7C its Wiki page].

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.
