I was wondering whether anyone on this list has the facilities for
etching silicon? I have a requirement for a circular piece of silicon
(around 0.5mm thick) to be etched with a 2mm square cavity approx.
0.3mm deep. The sides of the hole should be around 50 degrees taper.
In the centre of the cavity, there should be a small hole, around
I have the actual drawings if anyone is able to fabricate such a
piece. Please contact me off-list if you are able to assist.
