Abstract:
A semiconductor device includes a semiconductor substrate, a plurality of semiconductor fins, a gate stack and an epitaxy structure. The semiconductor fins are present on the semiconductor substrate. The semiconductor fins respectively include recesses therein. The gate stack is present on portions of the semiconductor fins that are adjacent to the recesses. The epitaxy structure is present across the recesses of the semiconductor fins. The epitaxy structure includes a plurality of corners and at least one groove present between the corners, and the groove has a curvature radius greater than that of at least one of the corners.

Claim (Index 10):
A method comprising:\n forming a first semiconductor fin and a second semiconductor fin over a substrate; forming a first gate stack on the first and second semiconductor fins; recessing the first and first and second semiconductor fins outside of the first gate stack; epitaxially growing a first epitaxy structure in the recesses of the first and second semiconductor fins, the first epitaxy structure comprising a first epitaxial layer and a second epitaxial layer, the first epitaxy structure extending from the first semiconductor fin to the second semiconductor fin, the first epitaxy structure having a topmost surface that includes a first corner, a second corner, and a first groove, the first corner being over the first semiconductor fin and the second corner being over the second semiconductor fin, the first groove extending from the first corner to the second corner, the first groove comprising the first epitaxial layer; and etching the first epitaxy structure to form a shaped epitaxy structure, the etching forming a first rounded corner from the first corner, a second rounded corner from the second corner, and a second groove from the first groove, the second groove comprising the first and second epitaxial layers.
