A talk with Christophe Maleville, of Soitec in France. They manufacture
SOI wafers, so naturally this a very pro-SOI interview. But I'm sure it
can be educational, nonetheless.

They use a somewhat unusual technique to make soi. You will recall that
there are companies that have been in mass production of SOI for some
years including IBM, Chartered, and the perennial favorite AMD.

And where do you think most(if not all) of these companies get their SOI
wafers from?

I know for a fact that Soitec is the supplier of SOI wafers to AMD.
Probably Chartered and IBM also get their's from these guys, since they
have such an interlinked development process with each other.

"AMD has announced it is moving to SOI for 90-nanometer and below
technologies."

I thought that AMD had moved to SOI at 130nm... in fact from the beginning
of AMD64... and about 3 years ago, they had to jump ship from Moto to IBM
to get the process right.

yes you are indeed correct. my information was out of date and IBM does
get some bonded wafers.

Yup, that's my understanding too.

Just the facts. ...but perhaps not all of 'em.
 
QUOI? Some secrets that never saw the light of day?;-)

QUOI??? Sure, but if they ever saw the light-of-day they wouldn't be
secrets, eh? ;-)

AMD and IBM have always had a close relationship. In the K6 days it was
quite close. Motorola and IBM had a rather close relationship too, but...
Notice *when* AMD decided to go with Moto for SOI, then changed their
mind. Also notice how many SOI products Moto pushed out the door. SOI was
a whistling-bitch to tame.

From an ancient data book (6802 era, perhaps pre-6809) I remember a
chip with SOS technology - Silicon On Sapphire.

Does anyone know where that went? Did it ever work? Why isn't it used today?

It is still around. Wafers are way expensive, and smaller than Silicon
wafers used nowdays.

Whatever happened to gallium arsenide? wasn't that the next big thing
a few years ago?

It's still arround, but mostly used for analog and bipolar stuff, not
much for logic. SiGe has a lot of advantages though.
