摘要： An example process to remove spacers from the gate of a NMOS transistor. A stress creating layer is formed over the NMOS and PMOS transistors and the substrate. In an embodiment, the spacers on gate are removed so that stress layer is closer to the channel of the device. The stress creating layer is preferably a tensile nitride layer. The stress creating layer is preferably a contact etch stop liner layer. In an embodiment, the gates, source and drain region have an silicide layer thereover before the stress creating layer is formed. The embodiment improves the performance of the NMOS transistors.

摘要： An example method embodiment forms spacers that create tensile stress on the substrate on both the PFET and NFET regions. We form PFET and NFET gates and form tensile spacers on the PFET and NFET gates. We implant first ions into the tensile PFET spacers to form neutralized stress PFET spacers. The neutralized stress PFET spacers relieve the tensile stress created by the tensile stress spacers on the substrate. This improves device performance.

摘要： A method of forming a relaxed silicon-germanium layer for use as an underlying layer for a subsequent overlying tensile strain silicon layer, has been developed. The method features initial growth of a underlying first silicon-germanium layer on a semiconductor substrate, compositionally graded to feature the largest germanium content at the interface of the first silicon-germanium layer and the semiconductor substrate, with the level of germanium decreasing as the growth of the graded first silicon-germanium layer progresses. This growth sequence allows the largest lattice mismatch and greatest level of threading dislocations to be present at the bottom of the graded silicon-germanium layer, with the magnitude of lattice mismatch and threading dislocations decreasing as the growth of the graded silicon-germanium layer progresses. In situ growth of an overlying silicon-germanium layer featuring uniform or non-graded germanium content, results in a relaxed silicon-germanium layer with a minimum of dislocations propagating from the underlying graded silicon-germanium layer. In situ growth of a silicon layer results in a tensile strain, low defect density layer to be used for MOSFET device applications.

摘要： An embodiment of fabrication of a variable work function gates in a FUSI device is described. The embodiment uses a work function doping implant to dope the polysilicon to achieve a desired work function. Selective epitaxy growth (SEG) is used to form silicon over the source/drain regions. The doped poly-Si gate is fully silicided to form fully silicided gates that have a desired work function. We provide a substrate having a NMOS region and a PMOS region. We form a gate dielectric layer and a gate layer over said substrate. We perform a (gate Vt) gate layer implant process to implant impurities such as P+, As+, B+, BF2+, N+, Sb+, In+, C+, Si+, Ge+ or Ar+ into the gate layer gate in the NMOS gate regions and said PMOS gate regions. We form a cap layer over said gate layer. We pattern said cap layer, said gate layer and said gate dielectric layer to form a NMOS gate and a PMOS gate. Spacers are formed and S/D regions are formed. A metal is deposited over said substrate surface. We anneal said metal layer to form fully silicided NMOS gate and fully silicided PMOS gate.
