Abstract
An integrated circuit structure includes a semiconductor substrate, and isolation regions extending into the semiconductor substrate, wherein the isolation regions have opposite sidewalls facing each other. A fin structure includes a silicon fin higher than top surfaces of the isolation regions, a germanium-containing semiconductor region overlapped by the silicon fin, silicon oxide regions on opposite sides of the germanium-containing semiconductor region, and a germanium-containing semiconductor layer between and in contact with the silicon fin and one of the silicon oxide regions.
