EVENING PANEL SESSION (NOVEMBER

16,

1983)

SOI TECHNOLOGIES FOR INTEGRATED CIRCUITS

Moderator:

John C. C. Fan, MIT Lincoln Laboratory,

Massachusetts

Panel Members: Y. G. J. C. P.

Akasaka, Mitsubishi Electric Corporation, Japan W. Cullen, RCA Laboratories, New Jersey F. Gibbons, Stanford Electronic Laboratories, California Hill, Plessey Research Ltd., England J. Vail, Rome Air Development Center, Massachusetts

There are a number of viable approaches to silicon-on-insulator (SOI) technologies, and the panel session has assembled a number of leaders in the SOI community for their views of "SOI Technologies for Integrated Circuits." Their viewpoints, shown in tabulated form, were presented for general discussion in the session which was attended by about 150 people. Although SOI technologies are useful for many applications, most of the panelists agreed that the most appropriate near-term applications are for high-speed, high-density integrated circuits. Various SOI technologies, including silicon-on-sapphire (SOS), are currently in the running, but the majority of the panelists felt that for SOI technologies to be widely adopted, SOI must be available as a proven manufactured product within two to three years.
