Abstract

Fluorine containing regions (70) are formed in the source and drain regions (60) of the MOS transistor. A metal layer (90) is formed over the fluorine containing regions (70) and the source and drain regions (60). The metal layer is reacted with the underlying fluorine containing regions to form a metal silicide.
