Folks: I have an urgent need for DRIE of silicon carbide to augment our capability here. Typical features are: Depth = 300 microns Minimum feature size : 200 microns Wafer size : 4 in (to be supplied by NASA) Etch mask = Electroplated Nickel (will be done at NASA) Number of wafers = 20 Delivery date = July 15 DRIE etch rate of SiC is typically about 1 micron/min (Plasmatherm or STS). Given the urgency of this need, only the experienced need to respond. That said, I will be glad to discuss future collaboration with interested parties. Thanks. Robert S.
