For the high resistivity silicon wafers you can contact Topsil in
Frederikssund. We manufacture silicon by the Float zone method up to 15.000
Ohmcm, and we might have some extra wafers on stock. Try our sales

Emne: [mems-talk] Quartz glass and HRSS wafer requested

Hi people,

I'm looking for quartz glass (and no other type of glass) and for
high resistivity silicon substrates (>=3000 Ohm cm), both 100 mm
(probably also smaller), thickness about 500 um.
Volume: 3-5 pieces.
Does anybody know companies delivering low quantities of these
substrates? Does anybody of you have some of them in your stock and
you'd like to get rid of them?

Thanks for your help,
--
