I would like to place one to several sub-micron holes in a film of chromium
on a glass slide.  The chromium does not have to be very thick, only enough
to block visible light, a few microns thick I think.

Anyone have a recommendation on methods or any services that can provide
this?

Thanks in advance,



Marco
