Patent number: 9752251Abstract: A self-limiting selective epitaxy process can be employed on a plurality of semiconductor fins such that the sizes of raised active semiconductor regions formed by the selective epitaxy process are limited to dimensions determined by the sizes of the semiconductor fins. Specifically, the self-limiting selective epitaxy process limits growth of the semiconductor material along directions that are perpendicular to crystallographic facets formed during the selective epitaxy process. Once the crystallographic facets become adjoined to one another or to a dielectric surface, growth of the semiconductor material terminates, thereby preventing merger among epitaxially deposited semiconductor materials.Type: GrantFiled: April 15, 2013Date of Patent: September 5, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Kevin K. Chan, Eric C. Harley, Yue Ke, Annie Levesque

Patent number: 9412843Abstract: A method of manufacturing a semiconductor device with an embedded layer, by anisotropically etching a substrate adjacent to an already formed gate structure. A dummy layer is deposited in the previously etched region, and a second spacer is formed next to the first spacer. The dummy layer is removed, and a second anisotropic etch is performed. A semiconductor substrate is then epitaxially grown in the etched out region to form the embedded layer.Type: GrantFiled: May 23, 2014Date of Patent: August 9, 2016Assignee: International Business Machines CorporationInventors: Eric C.

Patent number: 9390884Abstract: A semiconductor substrate inspection system includes an e-beam inspection system configured to deliver electrons to a specimen semiconductor substrate. A sensor is configured to detect reflected electrons that reflect off the surface of the specimen semiconductor substrate. An analysis unit is configured to determine a number of electrons received by the semiconductor substrate, and to determine at least one target region including at least one defect of the semiconductor substrate. A reference image module is in electrical communication with the analysis unit. The reference image module is configured to generate a first digital image having a plurality of pixels, and to adjust a gray-scale level of the pixels included in the target region based on the number electrons included in each pixel to generate a second digital image that excludes the at least one defect.Type: GrantFiled: May 9, 2014Date of Patent: July 12, 2016Assignee: GLOBALFOUNDRIES INC.Inventors: Eric C.

Publication number: 20160079397Abstract: A semiconductor fin suspended above a top surface of a semiconductor layer and supported by a gate structure is formed. An insulator layer is formed between the top surface of the semiconductor layer and the gate structure. A gate spacer is formed, and physically exposed portions of the semiconductor fin are removed by an anisotropic etch. Subsequently, physically exposed portions of the insulator layer can be etched with a taper. Alternately, a disposable spacer can be formed prior to an anisotropic etch of the insulator layer. The lateral distance between two openings in the dielectric layer across the gate structure is greater than the lateral distance between outer sidewalls of the gate spacers. Selective deposition of a semiconductor material can be performed to form raised active regions.Type: ApplicationFiled: November 23, 2015Publication date: March 17, 2016Applicant: GLOBALFOUNDRIES INC.Inventors: Kangguo Cheng, Eric C.

Patent number: 9246003Abstract: A semiconductor structure may include a semiconductor fin, a gate over the semiconductor fin, a spacer on a sidewall of the gate, an angled recess region in an end of the semiconductor fin beneath the spacer, and a first semiconductor region filling the angled recess. The angled recess may be v-shaped or sigma shaped. The structure may further include a second semiconductor region in contact with the first semiconductor region and the substrate. The structure may be formed by forming a gate above a portion of the semiconductor fin on a substrate, forming a spacer on a sidewall of the gate; removing a portion of the semiconductor fin not covered by the spacer or the gate to expose a sidewall of the fin, etching the sidewall of the fin to form an angled recess region beneath the spacer, and filling the angled recess region with a first epitaxial semiconductor region.Type: GrantFiled: November 19, 2013Date of Patent: January 26, 2016Assignee: GLOBALFOUNDRIES INC.Inventors: Kangguo Cheng, Eric C.

Patent number: 9236477Abstract: Silicon-carbon alloy structures can be formed as inverted U-shaped structures around semiconductor fins by a selective epitaxy process. A planarization dielectric layer is formed to fill gaps among the silicon-carbon alloy structures. After planarization, remaining vertical portions of the silicon-carbon alloy structures constitute silicon-carbon alloy fins, which can have sublithographic widths. The semiconductor fins may be replaced with replacement dielectric material fins. In one embodiment, employing a patterned mask layer, sidewalls of the silicon-carbon alloy fins can be removed around end portions of each silicon-carbon alloy fin. An anneal is performed to covert surface portions of the silicon-carbon alloy fins into graphene layers. In one embodiment, each graphene layer can include only a horizontal portion in a channel region, and include a horizontal portion and sidewall portions in source and drain regions.Type: GrantFiled: February 17, 2014Date of Patent: January 12, 2016Assignee: GLOBALFOUNDRIES INC.Inventors: Jack O.
