  • Patent number: 8438509
    Abstract: A method of automated generation of oxide pillar (PX) slot shapes of a PX layer within silicon-on-insulator (SOI) structures that includes generating a placement grid on recess oxide (RX) shapes, creating PX placement markers on the placement grid along a perimeter of the RX shapes, filtering the PX placement markers, generating a PX slot shape corresponding to each filtered PX placement marker on the RX shapes, correcting location errors associated with the generated PX slot shapes, generating PX slot shapes on RX shapes of a predetermined size for which PX slot shapes were not generated, performing a verification operation of the PX slot shapes, and outputting the PX layer including the verified PX slot shapes.

  • Patent number: 6998699
    Abstract: A bipolar transistor having a base contact surrounded by an emitter contact. A plurality of wires extending from the base contact and the emitter contact of the bipolar transistor, wherein the wires of the base contact are stacked higher than the wires of the emitter contact. A device comprising a plurality of these bipolar transistors, wherein at least one side of each emitter contact abuts each adjacent transistor. Increasing the wiring stack of each row of transistors in the device as the distance between the row and the current input increases.

  • Patent number: 5631495
    Abstract: High-performance bipolar transistors with improved wiring options and fabrication methods therefore are set forth. The bipolar transistor includes a base contact structure that has multiple contact pads which permit multiple device layouts when wiring to the transistor. For example, a first device layout may comprise a collector-base-emitter device layout, while a second device layout may comprise a collector-emitter-base device layout. More specifically, the base contact structure at least partially surrounds the emitter and has integral contact pads which extend away from the emitter. Further, sections of the base contact structure are disposed on an insulating layer outside of the perimeter of the base region of the transistor, while other sections directly contact the base region. Specific details of the bipolar transistor, and fabrication methods therefore are also set forth.
