  • Method and system for integrating shallow trench and deep trench isolation structures in a semiconductor device
    Patent number: 6667226
    Abstract: A semiconductor device and a method for constructing a semiconductor device is disclosed. A deep trench isolation structure (108) is formed proximate a surface of a semiconductor substrate (106). A deep trench plug (122) layer is deposited within the deep trench isolation structure (108). A shallow trench isolation structure (130) is formed where the deep trench isolation structure (108) meets the surface of the semiconductor substrate (106). A shallow trench plug layer (133) is deposited within the shallow trench isolation structure (130).
    Type: Grant
