    摘要: A semiconductor process and apparatus includes forming channel orientation CMOS transistors (24, 34) with enhanced hole mobility in the NMOS channel region and reduced channel defectivity in the PMOS region by depositing a first tensile etch stop layer (51) over the PMOS and NMOS gate structures, etching the tensile etch stop layer (51) to form tensile sidewall spacers (62) on the exposed gate sidewalls, and then depositing a second hydrogen rich compressive or neutral etch stop layer (72) over the NMOS and PMOS gate structures (26, 36) and the tensile sidewall spacers (62). In other embodiments, a first hydrogen-rich etch stop layer (81) is deposited and etched to form sidewall spacers (92) on the exposed gate sidewalls, and then a second tensile etch stop layer (94) is deposited over the NMOS and PMOS gate structures (26, 36) and the sidewall spacers (92).

    摘要: Solutions for forming an integrated circuit structure having a substantially planar N-P step height are disclosed. In one embodiment, a method includes: providing a structure having an n-type field effect transistor (NFET) region and a p-type field effect transistor (PFET) region; forming a mask over the PFET region to leave the NFET region exposed; performing dilute hydrogen-flouride (DHF) cleaning on the exposed NFET region to substantially lower an STI profile of the NFET region; and forming a silicon germanium (SiGE) channel in the PFET region after the performing of the DHF.
