ABSTRACT:
A submicron MOSFET is fabricated on an ultrathin layer with a generally intrinsic channel having a dopant concentration less than about 10.sup.16 cm.sup.-3. The channel thickness is preferably no greater than about 0.2 microns; the ratio of channel thickness to length is less than about 1:4, and preferably no greater than about 1:2. Punchthrough and other short-channel effects are inhibited by the application of an appropriate back-gate voltage, which may also be varied to adjust the voltage threshold.
