Abstract:
A semiconductor device includes a semiconductor substrate, a dielectric layer, a gate structure, a source semiconductor feature, and a drain semiconductor feature. The semiconductor substrate has an active area and a shallow trench isolation (STI) structure surrounding the active area. The semiconductor substrate includes a protrusion structure in the active area and has an undercut at a periphery of the active area. The dielectric layer overlays the protrusion structure of the semiconductor substrate and fills at least a portion of the undercut of the protrusion structure. The gate structure crosses over the protrusion structure. The source semiconductor feature and the drain semiconductor feature are located in the active area and positioned at opposite sides of the gate structure.

Claim (Index 4):
The semiconductor device of  claim 1 , wherein the protrusion structure has a top and a bottom, wherein a width of the bottom is about 99-70% of a width of the top.
