Illuminate the part from the side and the marks should be readilly visible.

Subject: [mems-talk] seeing glass alignment keys


> Hello,

> An interesting problem has arisen and I was wondering if anyone had any
suggestions. I'm processing on glass chips and the first step is a glass
etch. However, this means that my first set of alignment marks are
transparent and I'm having a hard time finding them with the aligner to line
up the next mask. I've tried darkening them in with a marker but that
doesn't seem to help. Any ideas? Thanks much.
