silicon 'rounding' etch
Jim Beall

Greetings -

We are looking for a wet etch to round or smooth the knife edges
formed at the bottom edges of KOH etched through-holes in silicon.
Something that preferentially attacks sharp points would be
preferable. Plasma/RIE etches involving CF4, SF6, CHF3, O2 are also
possible.

Any hints would be appreciated.

Jim
