Abstract

See full text

A method of forming a semiconductor structure includes providing a semiconductor substrate, forming at least one precursor semiconductor fin from the semiconductor substrate, etching through at least a portion of the at least one precursor semiconductor fin to form at least one patterned precursor semiconductor fin having a gap therein. The at least one patterned precursor semiconductor fin includes a first vertical surface and a second vertical surface with the gap therebetween. In addition, the method further includes forming a semiconductor material in the gap of the at least one patterned precursor semiconductor fin, in which the first vertical surface and the second vertical surface laterally surround the semiconductor material, and transforming the at least one patterned precursor semiconductor fin into at least one semiconductor fin including the semiconductor material therein.
