    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.

    摘要: The embodiments of methods and structures are for doping fin structures by plasma doping processes to enable formation of shallow lightly doped source and drain (LDD) regions. The methods involve a two-step plasma doping process. The first step plasma process uses a heavy carrier gas, such as a carrier gas with an atomic weight equal to or greater than about 20 amu, to make the surfaces of fin structures amorphous and to reduce the dependence of doping rate on crystalline orientation. The second step plasma process uses a lighter carrier gas, which is lighter than the carrier gas for the first step plasma process, to drive the dopants deeper into the fin structures. The two-step plasma doping process produces uniform dopant profile beneath the outer surfaces of the fin structures.

    摘要: A method of performing rapid thermal annealing on a substrate including heating the substrate to a first temperature in a rapid thermal annealing system having a front-side heating source and a backside heating source. The method further includes raising the temperature of the substrate from the first temperature to a second temperature greater than the first temperature. The backside heating source provides a greater amount of heat than the front-side heating source during the raising of the temperature of the substrate.

    摘要: Rapid thermal annealing methods and systems for annealing patterned substrates with minimal pattern effect on substrate temperature non-uniformity are provided. The rapid thermal annealing system includes a front-side heating source and a backside heating source. The backside heating source of the rapid thermal annealing system supplies a dominant amount of heat to bring the substrate temperature to the peak annealing temperature. The front-side heating source contributes to heat up the environment near the front-side of the substrate to a temperature lower than about 100° C. to about 200° C. less than the peak annealing temperature. The asymmetric front-side and backside heating for rapid thermal annealing reduce or eliminate pattern effect and improve WIW and WID device performance uniformity.
