Roger Key has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060252215
    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.

  • Publication number: 20060087401
    Abstract: A resistor formed on a material layer of a semiconductor integrated circuit and a method for forming the resistor. The resistor comprises a region of resistive material with a plurality of conductive contacts or plugs in electrical contact with and extending away from the resistive material. A first and a second interconnect line are formed overlying the plugs and in conductive contact with one or more of the plurality of plugs, such that a portion of the resistive material between the first and the second interconnect lines provides a desired resistance. According to a method of the present invention, the plurality of conductive contacts are formed using a first photolithographic mask and the first and the second interconnect lines are formed using a second photolithographic mask. The desired resistance is changed by modifying the first or the second mask such that one or more dimensions of a region of the resistive material between the first and the second interconnect lines is altered.

  • Patent number: 5845065
    Abstract: A method and apparatus for controlling operation of remote networked devices, such as computers, in compliance with licensed restrictions is provided. In one embodiment, licenses are assigned to users in the order of application requests that are made. When a request is made and no licenses are available, an analysis is performed to determined whether licenses may be swapped in such a fashion so as to free up a license for the requested application. In another embodiment, whenever a new request is made, an analysis performed by considering the needs of users. Information needed to perform the analysis is stored in the database which is updated when a new program launch occurs.
