  • Epitaxial silicon germanium for reduced contact resistance in field-effect transistors
    Patent number: 7851291
    Abstract: A method for selectively relieving channel stress for n-channel transistors with recessed, epitaxial SiGe source and drain regions is described. This increases the electron mobility for the n-channel transistors without affecting the strain in p-channel transistors. The SiGe provides lower resistance when a silicide is formed.
    Type: Grant
    Filed: May 26, 2009
    Date of Patent: December 14, 2010
    Assignee: Intel Corporation
