Abstract
A method of forming a semiconductor device includes forming a gate stack over a substrate, forming an amorphized region in the substrate adjacent to an edge of the gate stack, forming a stress film over the substrate, performing a process to form a dislocation with a pinchoff point in the substrate, removing at least a portion of the dislocation to form a recess cavity with a tip in the substrate, and forming a source/drain feature in the recess cavity.
