Abstract
The present disclosure provides one embodiment of a semiconductor structure. The semiconductor structure includes a semiconductor substrate of a first semiconductor material; shallow trench isolation (STI) features formed in the semiconductor substrate; and a fin-like active region of a second semiconductor material epitaxy grown on the semiconductor substrate. The first semiconductor material has a first lattice constant and the second semiconductor material has a second lattice constant different from the first lattice constant. The fin-like active region further includes fluorine species.
