  • FinFET device and method of forming the same
    Patent number: 10115639
    Abstract: A method may include depositing a first conductive material in an opening disposed between a first semiconductor structure and a second semiconductor structure, the first conductive material comprising at least one first void. The method further includes removing a portion of the first conductive material to form a trench, the trench exposing the at least one first void and being defined by a remaining portion of the first conductive material; and depositing a second conductive material in the trench, the second conductive material and the remaining portion of the first conductive material forming a dummy gate layer.
    Type: Grant
    Filed: January 20, 2017
    Date of Patent: October 30, 2018
    Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.
    Inventors: Ping Hung Li, Lun-Kuang Tan, Hui-Ying Lu, Chia-Ao Chang
