Abstract:
1. A method of forming a device comprised of a plurality of fins and a plurality of trenches formed in a substantially un-doped layer of semiconducting material, the method comprising: identifying a top width of each of said plurality of fins and a depth of each of said plurality of trenches such that, during operation, said device is adapted to operate in at least three distinguishable conditions depending upon a voltage applied to said device; performing at least one process operation to define said plurality of trenches in said substantially un-doped layer of semiconducting material, wherein said trenches define said plurality of fins in said substantially un-doped layer of semiconducting material; forming a gate insulation layer on said plurality of fins and on a bottom surface of each of said trenches; and forming a gate electrode above said gate insulation layer.
