Abstract:
1. A semiconductor device, comprising: a substrate; a fin projecting upwardly from or through an upper surface of the substrate, the fin including a first semiconductor layer portion formed from a corresponding first semiconductor material, the fin being interposed between and longitudinally extending between a semiconductive source region portion and a semiconductive drain region portion; wherein the fin includes a semiconductive channel region joining the source region portion and the drain region portion, the channel region being of a first conductivity type; and wherein the fin further includes at least first and second channel control regions adjoining the channel region and configured for selectively creating charge depletion zones for thereby selectively controlling electrical conduction through the channel region, the at least two channel control regions being respectively formed along respective and opposed sidewall portions of the channel region and the channel control regions having a second conductivity type which is opposite to the first conductivity type; and a gate adjoining and electrically connecting to the channel control regions from outer sides of the channel control regions.
