Hi Alissa,

During the overetch, the Al etch chamber will be contaminated by the
decomposition products of the PDMS. So the important question what is in
PDMS and is it a problem to other users of the chamber. My concern is
what metals at in PDMS and at what level. Can you find a purity analysis
for PDMS?

    Thanks, Jim
