 aligning not good
Message-ID: <30696876.62.1358884855767.JavaMail.coral@snc-coraldb.stanford.edu>

Just to let you know: Backside aligning on KS2 does not give good aligning for me. The image is hard to get in focus but even worse is it that when I put the wafer under the BS microscope it looks expanded and both side cannot be aligned at the same time. Same wafer on KS1 looked totally normal so the expansion is not real. The microscope also gives a blurry picture of the wafer and the right part of the screen is flashing a lot so again the focus is really bad making good aligning hard to obtain.

Who ever has used the filter last, has not put it back.
I have a labmember ready to expose and not able to locate the filter.

If you have it,    bring it back ASAP( i mean now) , this is a community 
item.
