  • SiC semiconductor device with self-aligned contacts, integrated circuit and manufacturing method
    Patent number: 8188482
    Abstract: One aspect includes a semiconductor device with self-aligned contacts, integrated circuit and manufacturing method. One embodiment provides gate control structures. Each of the gate control structures is configured to control the conductivity of a channel region within a silicon carbide substrate by field effect. A contact hole is self-aligned to opposing sidewalls of adjacent gate control structures by intermediate spacers.
    Type: Grant
    Filed: December 22, 2008
    Date of Patent: May 29, 2012
    Assignee: Infineon Technologies Austria AG
    Inventors: Michael Treu, Kathrin Rueschenschmidt, Oliver Haeberlen, Franz Auerbach
