The Nanofab has a current job opening for a Process/Wafer-Fab Engineer, see the [https://wiki.nanofab.ucsb.edu/wiki/Nanofab_Job_Postings NanoFab Job Openings page] for details.


However, the repaired bell jar mount is not sliding down the hoist pole like it should. Since the repair involved some welding to the collar that slides down the hoist pole, we surmise that the concentricity was affected by the heat. The mount is back at the machine shop getting honed out. I should have it back to test late today/early tomorrow but it may have to go back again. Once it is able to slide on properly the tool should be up shortly thereafter.

ASML: intermittent alignment failures

I have determined that the laser used for Alignment is failing, the power is low and it flickers.

We will order a replacement ASAP and schedule an ASML engineering visit to install + calibrate a new one.

In the mean time, I'm sorry to say that you will see intermittent "reject" wafers. Please see email for info on recovering from this error.
