Abstract:
1. A method for manufacturing a semiconductor device, the method comprising: providing a mask on a semiconductor member; providing a dummy element to cover a portion of the mask, the portion of the mask overlapping a first portion of the semiconductor member, the dummy element further covering a second portion of the semiconductor member, the second portion of the semiconductor member being adjacent to the first portion of the semiconductor member; removing a third portion of the semiconductor member, the third portion of the semiconductor having not been covered by the mask or the dummy element; epitaxially growing a silicon compound on at least a surface of the first portion of the semiconductor member; removing the dummy element to expose the portion of the mask and to expose the second portion of the semiconductor member; removing the second portion of the semiconductor member; and forming a gate structure that overlaps the first portion of the semiconductor member.
