Abstract:
A three dimensional FET device structure which includes a plurality of three dimensional FET devices. Each of the three dimensional FET devices include an insulating base, a three dimensional fin oriented perpendicular to the insulating base, a gate dielectric wrapped around the three dimensional fin and a gate wrapped around the gate dielectric and extending perpendicularly to the three dimensional fin, the three dimensional fin having a device width being defined as the circumference of the three dimensional fin in contact with the gate dielectric. At least a first of the three dimensional FET devices has a first device width while at least a second of the three dimensional FET devices has a second device width. The first device width is different than the second device width. Also included is a method of making the three dimensional FET device structure.
