    摘要: The embodiments described provide mechanisms for doping oxide in the STIs with carbon to make etch rate in the narrow and wide structures equal and also to make corners of wide STIs strong. Such carbon doping can be performed by ion beam (ion implant) or by plasma doping. The hard mask layer can be used to protect the silicon underneath from doping. By using the doping mechanism, the even surface topography of silicon and STI enables patterning of gate structures and ILD0 gapfill for advanced processing technology.

In one embodiment, a method includes providing a semiconductor substrate and forming a metal silicide on the semiconductor substrate. In addition, the method includes treating an exposed surface of the metal silicide with a hydrogen/nitrogen-containing compound to form a treated layer on the exposed surface, where the composition of the treated layer hinders oxidation of the exposed surface. The method may then further include depositing a dielectric layer over the treated layer and the exposed surface of the metal silicide.
