Abstract: A method of fabricating a complementary metal oxide semiconductor (CMOS) device, wherein the method comprises forming a first well region (103) in a semiconductor substrate (102) for accommodation of a first type semiconductor device (130); forming a second well region (104) in the semiconductor substrate (102) for accommodation of a second type semiconductor device (140); shielding the first type semiconductor device (130) with a mask (114); depositing a first metal layer (118) over the second type semiconductor device (140); performing a first salicide formation on the second type semiconductor device (140); removing the mask (114); depositing a second metal layer (123) over the first and second type semiconductor devices (130,140); and performing a second salicide formation on the first type semiconductor device (130). The method requires only one pattern level and it eliminates pattern overlay as it also simplifies the processes to form different suicide material over different devices.

Abstract: A structure and method for a metal replacement gate of a high performance device is provided. A sacrificial gate structure (260) is first formed on an etch stop layer (250) provided on a semiconductor substrate (240). A pair of spacers (400) is provided on sidewalls of the sacrificial gate structure (300). The sacrificial gate structure (300) is then removed, forming an opening (600). Subsequently, a metal gate (1000) including an first layer (700) of metal such as tungsten, a diffusion barrier (800) such as titanium nitride, and a second layer (900) of metal such as tungsten is formed in the opening (600) between the spacers (400).

Abstract: A p-type field effect transistor (PFET) (10) and an n-type field effect transistor (NFET) (12) of an integrated circuit are provided. A first strain is applied to the channel region (20) of the PFET (10) but not the NFET (12) via a lattice-mismatched semiconductor layer such as silicon germanium disposed in source and drain regions (111) of only the PFET (10) and not of the NFET.(12) A process of making the PFET (10) and NFET (12) is provided. Trenches are etched in the areas to become the source and drain regions (111) of the PFET and a lattice-mismatched silicon germanium layer (121) is grown epitaxially therein to apply a strain to the channel region of the PFET adjacent thereto. A layer of silicon (14) can be grown over the silicon germanium layer (121) and a salicide (68) formed from the layer of silicon to provide low-resistance source and drain regions (111).

Abstract: PROBLEM TO BE SOLVED: To minimize the associated complexity and cost in fabricating a CMOS structure containing silicide contacts and metal silicide gates.
SOLUTION: The method of integrating the silicide metal of a CMOS allows incorporation of silicide contacts (S/D and gates) and metal silicide gates using a self-alignment process (salicide) and at least one lithography process. The integration method allows at least two different thicknesses of metals deposited on a semiconductor substrate such that on some of the CMOS transistors thinner silicide metals are formed and used in the formation of gate contacts, whereas on the other CMOS transistors thicker silicide metals are formed and used in the formation of metal silicide gates. The integration method of the present invention can also be used to form multiple phases of metal silicide gates by varying the metal deposition thickness thus having differing amounts of metal present during metal gate formation.

Abstract: The present invention provides a complementary metal oxide semiconductor integration process whereby a plurality of silicided metal gates are fabricated atop a gate dielectric. Each silicided metal gate that is formed using the integration scheme of the present invention has the same silicide metal phase and substantially the same height, regardless of the dimension of the silicide metal gate. The present invention also provides various methods of forming a CMOS structure having silicided contacts in which the polySi gate heights are substantially the same across the entire surface of a semiconductor structure.
