    摘要: The present disclosure provides a method and system for characterizing a pattern loading effect. A method may include performing a reflectivity measurement on a semiconductor wafer and determining an anneal process technique based on the reflectivity measurement. The determining the anneal process technique may include determining a spatial distance for a reflectivity change using a reflectivity map generated using the reflectivity measurement. This spatial distance is compared with the thermal diffusion length associated with each of the plurality of anneal process techniques. In an embodiment, a thermal profile map and/or a device performance map may be provided.

    摘要: Mechanisms for forming source/drain (S/D) regions of field effect transistors (FETs) are provided. The mechanisms eliminate dislocations near gate corners and gate corner defects (GCDs), and maintain transistor performance. The mechanisms described involve using a post-deposition etch to remove residual dislocations near gate corners after a cyclic deposition and etching (CDE) process is used to fill a portion of the recess regions with an epitaxially grown silicon-containing material. The mechanisms described also minimize the growth of dislocations near gate corners during the CDE process. The remaining recess regions may be filled by another silicon-containing layer deposited by an epitaxial process without forming dislocations near gate corners. The embodiments described enable gate corners to be free of dislocation defects, preserve the device performance from degradation, and widen the process window of forming S/D regions without gate corner defects and chamber matching issues.

    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.

    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.
