  • Patent number: 8143120
    Abstract: A process for forming bipolar junction transistors having a plurality of different collector doping densities on a semiconductor substrate and an integrated circuit comprising bipolar junction transistors having a plurality of different collector doping densities. A first group of the transistors are formed during formation of a triple well for use in providing triple well isolation for complementary metal oxide semiconductor field effect transistors also formed on the semiconductor substrate. Additional bipolar junction transistors with different collector doping densities are formed during a second doping step after forming a gate stack for the field effect transistors. Implant doping through bipolar transistor emitter windows forms bipolar transistors having different doping densities than the previously formed bipolar transistors.
    Type: Grant
    Filed: February 14, 2011
    Date of Patent: March 27, 2012
    Assignee: Agere Systems Inc.

  • Patent number: 7498204
    Abstract: A thermally conductive structure for a semiconductor integrated circuit and a method for making the structure. The structure comprises one or more vertical and/or horizontal thermally conductive elements disposed proximate a device for improving thermal conductivity from the device to a substrate of the integrated circuit. In one embodiment a heat sink is affixed to the integrated circuit for heat flow from the integrated circuit. The method comprises forming openings in material layers overlying the semiconductor substrate, wherein the openings are disposed proximate the device and extend to the substrate. A thermally conductive material is formed in the openings to provide a thermal path from the device to the substrate.
