  • Publication number: 20050035466
    Abstract: The present invention uses wire bonding technology to bond interconnect materials that oxidize easily by using a wire with stable oxidation qualities. A passivation layer is formed on the semiconductor substrate to encapsulate the bonding pad made from the interconnect material such that the wire bonds with the passivation layer itself, not with the interconnect material. The passivation layer is selected to be a material that is metallurgically stable when bonded to the interconnect material. Since the wire is stable compared with the interconnect material, i.e., it does not readily corrode, a reliable mechanical and electrical connection is provided between the semiconductor device (interconnect material) and the wire, with the passivation layer disposed therebetween.

  • Patent number: 6838769
    Abstract: A bond pad is located over active circuitry formed within an integrated circuit device. A barrier film forms the bottom surface of the upper portion of a bond pad opening which also includes vias extending through the bottom surface to form a dual damascene structure. The bond pad is resistant to stress effects such as cracking, which can be produced when bonding an external wire to the bond pad, and therefore prevents leakage currents between the bond pads and the underlying circuitry.

  • Patent number: 6773994
    Abstract: An architecture and process for forming CMOS vertical replacement gate metal oxide semiconductor field-effect transistors is disclosed. The integrated circuit structure includes a semiconductor area with a major surface formed along a plane and first and second source/drain dopes regions formed in the surface. An insulating trench is formed between the first and second source/drain regions. A third doped region forming a channel of a different conductivity type than the first source/drain region is positioned over the first source/drain region. A fourth doped region is formed over the second source/drain region, having an opposite conductivity type with respect to the second source/drain region, and forming a channel region. Fifth and sixth source/drain regions are formed respectively over the third and fourth doped regions.

  • Patent number: 6762087
    Abstract: The present invention is directed to a process for forming a dual damascene structure and a capacitor. The process includes forming a stack including insulating layers and a stop layer. The stack is patterned so that the openings used to form the sidewall capacitors may be formed when the vias or grooves of the dual damascene structure is formed. In this way, the process for manufacturing the sidewall capacitors may be integrated with the dual damascene process without adding additional mask or etching steps.
