发明名称 NICKEL-SILICIDE FORMATION WITH DIFFERENTIAL PT COMPOSITION
摘要 Embodiments of the invention provide a method of forming nickel-silicide. The method may include depositing first and second metal layers (105, 106) over at least one of a gate, a source, and a drain region of a field-effect-transistor (FET) (100) through a physical vapor deposition (PVD) process, wherein the first metal layer (105) is deposited using a first nickel target material containing platinum (Pt), and the second metal layer (106) is deposited on top of the first metal layer using a second nickel target material containing no or less platinum than that in the first nickel target material; and annealing the first and second metal layers covering the FET to form a platinum-containing nickel- silicide layer (107) at a top surface of the gate, source, and drain regions.
