Abstract

In a semiconductor manufacturing method, a mask is disposed on a semiconductor layer or semiconductor substrate. The semiconductor layer or semiconductor substrate is etched in an area delineated by the mask to form a cavity. With the mask disposed on the semiconductor layer or semiconductor substrate, the cavity is lined to form a containment structure. With the mask disposed on the semiconductor layer or semiconductor substrate, the containment structure is filled with a base semiconductor material. After filling the containment structure with the base semiconductor material, the mask is removed. At least one semiconductor device is fabricated in and/or on the base semiconductor material deposited in the containment structure.
