  • Metal-oxide-semiconductor transistor and method of fabricating the same
    Patent number: 11195905
    Abstract: A metal-oxide-semiconductor (MOS) transistor includes a substrate. The substrate has a plurality of trenches extending along a first direction and located on a top portion of the substrate. A gate structure line is located on the substrate and extends along a second direction intersecting with the first direction and crossing over the trenches. A first doped line is located in the substrate, located at a first side of the gate structure line, and crosses over the trenches. A second doped line is located in the substrate, located at a second side of the gate structure line, and crosses over the trenches.
    Type: Grant
    Filed: March 19, 2019
    Date of Patent: December 7, 2021
    Assignee: UNITED MICROELECTRONICS CORP.
    Inventors: Hsiang-Hua Hsu, Liang-An Huang, Sheng-Chen Chung, Chen-An Kuo, Chiu-Te Lee, Chih-Chung Wang, Kuang-Hsiu Chen, Ke-Feng Lin, Yan-Huei Li, Kai-Ting Hu
