    摘要: The instant invention describes a programmable neuron MOSFET structure formed on SOI substrates. A number of input capacitor structures (241, 231) are formed on a SOI substrate. The substrate region of the capacitors (330, 340) are completely isolated from each other by isolation structures (270). In addition the transistor structure (210) of the neuron MOSFET is completely isolated from the capacitor structures (241, 231) by the isolation structure (270). The neuron MOSFET also comprises a contiguous floating conductive layer (200, 230, and 240) which forms the gate structure of the capacitors (230, 240) and the floating gate (200) of the transistor structure.

    摘要: A heterojunction bipolar transistor (30) in a silicon-on-insulator (SOI) structure is disclosed. The transistor collector (28), heterojunction base region (20), and intrinsic emitter region (25) are formed in the thin film silicon layer (6) overlying the buried insulator layer (4). A base electrode (10) is formed of polysilicon, and has a polysilicon filament (10f) that extends over the edge of an insulator layer (8) to contact the silicon layer (6). After formation of insulator filaments (12) along the edges of the base electrode (10) and insulator layer (8), the thin film silicon layer (6) is etched through, exposing an edge. An angled ion implantation then implants the heterojunction species, for example germanium and carbon, into the exposed edge of the thin film silicon layer (6), which after anneal forms the heterojunction base region (20). Polysilicon plugs for the emitter (24e) and collector (24c) are then formed, from which dopant diffuses to form the intrinsic emitter (25) and subcollector (22) of the device.

    摘要: A method for semiconductor processing provides a DSB semiconductor body having a first crystal orientation, a second crystal orientation, and a border region disposed between the first and second crystal orientations. The border region further has a defect associated with an interface of the first crystal orientation and second the second crystal orientation, wherein the defect generally extends a distance into the semiconductor body from a surface of the body. A sacrificial portion of the semiconductor body is removed from the surface thereof, wherein removing the sacrificial portion at least partially removes the defect. The sacrificial portion can be defined by oxidizing the surface at low temperature, wherein the oxidation at least partially consumes the defect. The sacrificial portion can also be removed by CMP. An STI feature may be further formed over the defect after removal of the sacrificial portion, therein consuming any remaining defect.
