Does anybody know whether anyone manufactures Si wafers that are p- and n-type
doped completely through the total thinkness of the wafer? The thickness of the
wafer does not matter to me; I need to make small (micron-sized) dopes Si
"powder", and thus would like to buy pre-doped wafers to grind up.
Alternatively, has anyone heard of doping micron-sized Si pieces in a furnace,
and whether there are any problems with doing this?

Thanks!
