Abstract:
A device includes a semiconductor substrate, a first fin arranged over the semiconductor substrate, and an isolation structure. The first fin includes an upper portion, a bottom portion, and an insulator layer between the upper portion and the bottom portion. A top surface of the insulator layer is wider than a bottom surface of the upper portion of the first fin. The isolation structure surrounds the bottom portion of the first fin.
