  • Epitaxial silicon germanium for reduced contact resistance in field-effect transistors
    Publication number: 20070231983
    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.
