Silicon-on-insulator (SOI) has emerged as a key technology for low pow
er electronics. The merits of SOI technology have been demonstrated, a
nd are gaining acceptance in the semiconductor industry. In order for
the SOI approach to be viable, several factors must converge, includin
g the availability of SOI substrates in sufficient quantity, of accept
able quality, and at a competitive price. This work describes developm
ents in SIMOX manufacturing technology and summarizes progress in each
of these areas.
