    摘要: Multi-stage preheat high-temperature anneal processes after the deposition of the gate dielectric layer(s) reduce the number of interfacial sites and improve the negative bias temperature instability (NTBI) performance of a p-type metal-oxide-semiconductor transistor (PMOS). The gate dielectric layers may include an interfacial oxide layer and a high-k dielectric layer. The multi-stage preheat is designed to reduce dopant deactivation and to improve inter-mixing between the interfacial oxide layer and the high-k dielectric layer. The high-temperature anneal is used to reduce the number of interfacial sites at the interface between the silicon substrate and the interfacial oxide layer.

    摘要: The embodiments described provide methods and structures 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.
