  • Patent number: 8273619
    Abstract: The invention includes methods of forming channel region implants for two transistor devices simultaneously, in which a mask is utilized to block a larger percentage of a channel region location of one of the devices relative to the other.

  • Patent number: 8237224
    Abstract: The method of manufacturing the semiconductor device that includes a high voltage MOS transistor with high operating voltage under both high and low gate voltages with low-cost is disclosed. When manufacturing the high voltage MOS transistor, a portion of a gate insulation film is removed to form an opening that exposes an outside area of the active area, which is outside of the central area where a gate electrode will be formed.

  • Patent number: 8187929
    Abstract: A method of fabricating a thin film transistor for an active matrix display using reduced masking operations includes patterning a gate on a substrate. A gate dielectric is formed over the gate and a semiconducting metal oxide is deposited on the gate dielectric. A channel protection layer is patterned on the semiconducting metal oxide overlying the gate to define a channel area and to expose the remaining semiconducting metal oxide. A source/drain metal layer is deposited on the structure and etched through to the channel protection layer above the gate to separate the source/drain metal layer into source and drain terminals and the source/drain metal layer and the semiconducting metal oxide are etched through at the periphery to isolate the transistor. A nonconductive spacer is patterned on the transistor and portions of the surrounding source/drain metal layer.

  • Patent number: 8138054
    Abstract: An enhanced FET capable of controlling current above and below a gate of the FET. The FET is formed on a semiconductor substrate. A source and drain are formed in the substrate (or in a well in the substrate). A first epitaxial layer of similar doping to the source and drain are grown on the source and drain, the first epitaxial layer is thicker than the gate, but not so thick as to cover the top of the gate. A second epitaxial layer of opposite doping is grown on the first epitaxial layer thick enough to cover the top of the gate. The portion of the second epitaxial layer above the gate serves as a body through which the gate controls current flow between portions of the first epitaxial layer over the drain and the source.
