[labnetwork] Polish Si wafer edge

[Kevin Roberts]

Bob,

At one point I was involved in making surgical scalpels from silicon, and
this required putting a beveled edge in silicon (15 or 20 degrees, just
like cutlery) and then chemically sharpening the edge. I would purchase
wafer dicing blades which had an angled edge to them instead of being flat.
I would get these blades from Thermoccarbon in Casselberry, FL. You could
ask them if they'd be willing to sell you some 45 degree'd blades; my guess
is they make these.

ThermoCarbon: https://dicing.com/

Regards,
Kevin
