    摘要: A method removes the spacers from the sides of a transistor gate stack, and after the spacers are removed, the method implants an additional impurity into surface regions of the substrate not protected by the gate conductor (or alternatively just amorphizes these surface regions, without adding more impurity). The method then performs a laser anneal on the additional impurity (to activate the additional impurity) or amorphized regions (to recrystallize the amorphized regions). After this, permanent spacers are formed on the sidewalls of the gate conductor. Then, the surface regions of the substrate not protected by the gate conductor and the permanent spacers are silicided, to create silicide source/drain regions. This forms the silicide regions in the additional impurity or in the recrystallized amorphized regions to reduce the source/drain resistance by improving the active dopant concentration at the silicon-silicide interface.

    摘要: A method of forming a semiconductor device includes implanting an amorphizing species into a crystalline semiconductor substrate, the substrate having a transistor gate structure formed thereupon. Carbon is implanted into amorphized regions of the substrate, with specific implant conditions tailored such that the peak concentration of carbon species coincides with the end of the stacking faults, where the stacking faults are created during the recrystallization anneal. The implanted carbon pins partial dislocations so as to prevent the dislocations from disassociating from the end of the stacking faults and moving to a region in the substrate directly below the transistor gate structure. This removes the defects, which cause device leakage fail.

    摘要: A method for reducing top notching effects in pre-doped gate structures includes subjecting an etched, pre-doped gate stack structure to a re-oxidation process, the re-oxidation process comprising a radical assisted re-oxidation process so as to result in the formation of an oxide layer over vertical sidewall and horizontal top surfaces of the etched gate stack structure. The resulting oxide layer has a substantially uniform thickness independent of grain boundary orientations of the gate stack structure and independent of the concentration and location of dopant material present therein.
