Claim:
1. A method of manufacturing a semiconductor device, the method comprising: forming a fin from a semiconductor substrate; removing a first section from a first corner region of the fin, the first corner region including a region of a first exposed end of the fin from a first side of the fin to a midline of the fin, the first section comprising a first lengthwise fin section from the first side toward the midline, wherein other portions of the first exposed portion of the fin remain substantially intact; removing a second section from a second corner region of the fin, the second corner region including a region of a second exposed end of the fin from a second side of the fin to a midline of the fin, the second section comprising a second lengthwise fin section from the second side of the fin toward the midline of the fin, wherein the second side of the fin is opposite the first side, wherein the second exposed end of the fin is opposite the first exposed end, and wherein other portions of the second exposed portion of the fin remain substantially intact; implanting first dopants to form a first source/drain region within the fin; and implanting second dopants to form a second source/drain region within the fin in physical contact with the first source/drain region, wherein the second source/drain region has an opposite conductivity than the first source/drain region.
