Abstract
An integrated circuit (IC) includes a semiconductor substrate, a least one MOS transistor formed in or on the substrate, the MOS transistor including a source and drain doped with a first dopant type having a channel region of a second dopant type interposed between, and a gate electrode and a gate insulator over the channel region. A silicide layer forming a low resistance contact is at an interface region at a surface portion of the source and drain. At the interface region a chemical concentration of the first dopant is at least 5×10cm. Silicide interfaces according to the invention provide MOS transistor with a low silicide interface resistance, low pipe density, with an acceptably small impact on short channel behavior.
