摘要:
Embodiments of the invention provide a method of forming embedded silicon germanium (eSiGe) in source and drain regions of a p-type field-effect-transistor (pFET) through a disposable spacer process; depositing a gap-filling layer directly on the eSiGe in the source and drain regions in a first process; depositing a layer of offset spacer material on top of the gap-filling layer in a second process different from the first process; etching the offset spacer material and the gap-filling layer, thus forming a set of offset spacers and exposing the eSiGe in the source and drain regions of the pFET; and finishing formation of the pFET.

摘要:
A semiconductor device and method of manufacture and, more particularly, a semiconductor device having strain films and a method of manufacture. The device includes an embedded SiGeC layer in source and drain regions of an NFET device and an embedded SiGe layer in source and drain regions of a PFET device. The PFET device is subject to compressive strain. The method includes embedding SiGe in source and drain regions of an NFET device and implanting carbon in the embedded SiGe forming an SiGeC layer in the source and drain regions of the NFET device. The SiGeC is melt laser annealed to uniformly distribute the carbon in the SiGeC layer, thereby counteracting a strain generated by the embedded SiGe.
摘要:
A sheet resistance stabilized recrystallized antimony doped region may be formed within a semiconductor substrate by annealing a corresponding antimony doped amorphized region at a temperature from about 1050° C. to about 1400° C. for a time period from about 0.1 to about 10 milliseconds. Preferably, a laser surface treatment is used. The laser surface treatment preferably uses a solid phase epitaxy. In addition, the antimony doped region may be co-doped with at least one of a phosphorus dopant and an arsenic dopant. The antimony dopant and the laser surface treatment lend sheet resistance stability that is otherwise absent when forming solely phosphorus and/or arsenic doped regions.
