Hello Andreas,

Most of the European foundries are still running 4" wafers and many are
planning not to switch to 6" until they are forced through supply of
equipment for 4" etc.

To my knowledge the following European foundries handle 6" Si wafers:

-BOSCH - Reutlingen, Germany
-Colibrys - Neuchatel, Switzerland (foundry spin off from CSEM in January
2001)
-FhG ISiT - Itzehoe, Germany
-OnStream, Holland
-ST, Italy
and X-Fab in Erfurt that you certainly know well

There are relatively more in the US the offer 6" wafer capacities.
Unfortunately, almost all of them will not be interested in small volumes
(however it is not always the volume that counts). To my knowledge most R&D
institutions do not offer 6" wafer runs, but generally 4".

One possibility might be the CMI at the EPFL in Lausanne. They have really
'nice' cleanroom facilities running on 6". You may contact Prof. Philippe
Renaud ([email protected]).

If you need more information, your are welcome to contact me.

Best regards
Gerold

Subject: Si wafer facilities for microsystem fabrication


Dear colleagues
who knows Si wafer manufacturing facilities in R&D institutes (because
of small to medium volume production) prefered in Germany and could tell
me which
wafer sizes are processed there.

There is an urgent need for 6" wafer foundry processes.
