  • DRAM with schottky barrier FET and MIM trench capacitor
    Patent number: 8343864
    Abstract: A semiconductor circuit and method of fabrication is disclosed. In one embodiment, the semiconductor circuit comprises a metal-insulator-metal trench capacitor in a silicon substrate. A field effect transistor is disposed on the silicon substrate adjacent to the metal-insulator-metal trench capacitor, and a silicide region is disposed between the field effect transistor and the metal-insulator-metal trench capacitor. Electrical connectivity between the transistor and capacitor is achieved without the need for a buried strap.
    Type: Grant
    Filed: March 28, 2011
    Date of Patent: January 1, 2013
    Assignee: International Business Machines Corporation
    Inventors: Puneet Goyal, Herbert Lei Ho, Pradeep Jana, Jin Liu
