Abstract: Methods of preparing conductive regions such as source/drain regions for silicidation procedures, has been developed. The methods feature removal of native oxide as well as removal of deposited arsenic based defects from conductive surfaces prior to deposition of a metal component of subsequently formed metal silicide regions. Arsenic ions implanted for N type source/drain regions are also implanted into insulator regions such as insulator filled shallow trench isolation regions. A hydrofluoric acid cycle used as a component of the pre-silicidation preparation procedure can release arsenic from the shallow trench isolation regions in the form of arsenic based defects, which in turn can re-deposit on the surface of source/drain region. Therefore pre-silicidation preparation treatments described in this invention feature removal of both native oxide and arsenic based defects from conductive surfaces prior to metal silicide formation.

Abstract: Method of improving adhesion of low dielectric constant films to other dielectric films and barrier metals in a damascene process are achieved. In one method, a low dielectric constant material layer is deposited on a substrate. Silicon ions are implanted into the low dielectric constant material layer. Thereafter, a TEOS-based silicon oxide layer is deposited overlying the low dielectric constant material whereby there is good adhesion between low dielectric constant material layer and the TEOS-based silicon oxide layer. In another method, a low dielectric constant material layer is deposited on a substrate. A silicon-based dielectric layer is deposited overlying the low dielectric constant material wherein the silicon-based dielectric layer is not silicon oxide whereby there is good adhesion between the low dielectric constant material layer and the silicon-based dielectric layer.

Abstract: Methods for forming dual-metal gate CMOS transistors are described. An NMOS and a PMOS active area of a semiconductor substrate are separated by isolation regions. A metal layer is deposited over a gate dielectric layer in each active area. Silicon ions are implanted into the metal layer in one active area to form an implanted metal layer which is silicided to form a metal silicide layer. Thereafter, the metal layer and the metal silicide layer are patterned to form a metal gate in one active area and a metal silicide gate in the other active area wherein the active area having the gate with the higher work function is the PMOS active area. Alternatively, both gates may be metal silicide gates wherein the silicon concentrations of the two gates differ. Alternatively, a dummy gate may be formed in each of the active areas and covered with a dielectric layer. The dielectric layer is planarized thereby exposing the dummy gates. The dummy gates are removed leaving gate openings to the semiconductor substrate.
