Abstract:
A semiconductor-on-insulator transistor comprising:an insulator layer; a semiconductor material layer over the insulator layer, the semiconductor material layer having an upper surface; an elongate transistor gate line disposed within and through the layer of semiconductor material and extending within the semiconductor material in a longitudinal direction, the gate having opposing lateral sides which extend in the longitudinal direction; a drain diffusion region received within the layer of semiconductor material on one of the lateral sides of the transistor gate and not extending to below the transistor gate, there being no drain diffusion region on the other of the lateral sides of the transistor gate, the drain diffusion region extending further along the transistor gate than a source diffusion region; a source diffusion region received within the layer of semiconductor material on said one of the lateral sides of the transistor gate, the source diffusion region being elevationally above the drain, there being no source diffusion region on said other of the lateral sides of the transistor gate; a source contact extending downwardly to the upper surface of the semiconductor material layer and to the source diffusion region; and a drain contact extending downwardly through the upper surface of the semiconductor material layer and to the drain diffusion region, the source and drain contacts laying in a plane running substantially parallel to the gate line.
