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.
