  • Method of fabricating ultra shallow junction CMOS transistors with nitride disposable spacer
    Patent number: 6551870
    Abstract: A method of developing a transistor, such as a complimentary MOS (CMOS) transistor, that includes lightly doped drain (LDD) regions which uses disposable spacers, and includes the step of adding an oxide spacer etch after a disposable nitride spacer removal and between source/drain implant and LDD implant. Because of this additional step, an ultra shallow LDD implant can be achieved. Moreover, uniformity of the depth of the junction is improved as the non-uniformity of the screen/liner oxide is eliminated.
    Type: Grant
    Filed: October 10, 2000
    Date of Patent: April 22, 2003
    Assignee: Advanced Micro Devices, Inc.
