Abstract:
1. A semiconductor device comprising: a source and a drain, said source and drain consisting essentially of silicide; a body formed from a semiconductor film disposed on an insulating layer, the insulting layer being disposed on a semiconductor substrate, the semiconductor film portion of the body being disposed between the source and the drain; a gate electrode disposed over the body and defining a channel interposed between the source and the drain; a gate dielectric separating the gate electrode and the body, said gate dielectric being made from a material having a relative permittivity of greater than about 10; a buffer interface disposed between the body and the gate dielectric; the buffer interface having a length equal to a length of the gate electrode; wherein a top portion of the source and a top portion of the drain are disposed at vertical heights that are at least as high as a portion of the gate dielectric; and wherein a bottom portion of the source and a bottom portion of the drain are each in physical contact with the insulating layer.
