Hey all,

I am looking for 3" or 4" wafers with 50 to 100 nm SiN films on both
sides.   I will make small tranparent membrane windows by wet etching.
I am looking for rebust, continuous SiN films.   Anybody know a source
that provides these wafers?

Please reply to my email address and not to the whole groups.  Thanks.
