Tantalum Coated Silicium Wafers

A PhD Student requested a quote for the following:

We want silicium wafers n dopped and p dopped. The n dopped silium must be covered on one side eith a tantalum layer of 100 nm and on the other side to be polished. The p silicon wafers must be  polished on the both sided.

Our lot charge for in-situ sputter etch followed by sputter deposition of 1,000Å Ta
Lot size = 12 wafers, 100mm dia.
