Abstract:
A method includes oxidizing a semiconductor fin to form an oxide layer on opposite sidewalls of the semiconductor fin. The semiconductor fin is over a top surface of an isolation region. After the oxidizing, a tilt implantation is performed to implant an impurity into the semiconductor fin. The oxide layer is removed after the tilt implantation.

Claim (Index 10):
A device comprising:\n a semiconductor substrate; a semiconductor strip overlying and connected to the semiconductor substrate, wherein the semiconductor strip comprises:\n a first sidewall that is substantially straight and in a first plane; \n a second sidewall that is substantially straight and in a second plane, wherein the first sidewall and the second sidewall are opposite sidewalls of the semiconductor strip; \n Shallow Trench Isolation (STI) regions contacting opposite sidewalls of the semiconductor strip; and a semiconductor fin protruding higher than a top surface of the STI regions, wherein the semiconductor fin has a first middle width measured at a middle height of the semiconductor fin, and wherein at the middle height, the first plane is spaced apart from the second plane with a second middle width therebetween, and the first middle width is smaller than about 75 percent of the second middle width.
