Patent number: 7898028Abstract: A process for fabricating a MOSFET device featuring a channel region comprised with a silicon-germanium component is provided. The process features employ an angled ion implantation procedure to place germanium ions in a region of a semiconductor substrate underlying a conductive gate structure. The presence of raised silicon shapes used as a diffusion source for a subsequent heavily-doped source/drain region, the presence of a conductive gate structure, and the removal of dummy insulator previously located on the conductive gate structure allow the angled implantation procedure to place germanium ions in a portion of the semiconductor substrate to be used for the MOSFET channel region. An anneal procedure results in the formation of the desired silicon-germanium component in the portion of semiconductor substrate to be used for the MOSFET channel region.Type: GrantFiled: August 23, 2007Date of Patent: March 1, 2011Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Sun-Jay Chang, Shien-Yang Wu
