Abstract
A field effect transistor (FET) is disclosed. In an exemplary embodiment of the invention, the FET includes an active semiconductor region defined upon a substrate, the active semiconductor region further having a mesa region formed therein. The FET also includes a gate formed within the active semiconductor region, the gate abutting the mesa region along one side thereof. The FET further includes a source region defined within a first area of the semiconductor region, the first region being located over an insulating layer, and a drain region defined within a second area of the semiconductor region, the second area also being located over the insulating layer. The first and second areas of the semiconductor region are located on opposite sides of the mesa region, and the insulating layer isolates the source region and the drain region from the substrate. In another exemplary embodiment, one of the source region or drain region is defined within a top surface of the mesa region.
