US Patent 7897513 Method for forming a metal silicide

The present application is directed to a method for forming a metal silicide layer. The method comprises providing a substrate comprising silicon and depositing a metal layer on the substrate. The metal layer is annealed within a first temperature range and for a first dwell time of about 10 milliseconds or less to react at least a portion of the metal with the silicon to form a silicide. An unreacted portion of the metal is removed from the substrate. The silicide is annealed within a second temperature range for a second dwell time of about 10 milliseconds or less.
