Fully-depleted, fully-inverted, short-length and vertical channel, dual-gate, cmos fet

摘要

A short-length vertical channel, dual-gate, CMOS FET obtains improved immunity to short channel effects. The FET has a plurality of vertically-extending channel segments and a gate structure with a plurality of vertically-orientated gate segments positioned between channel segments. A method of fabricating the FET involves forming the plurality of channel segments and reducing the width of the segments by subtractive oxidation in the spaces between the channels.
