  • Publication number: 20130020717
    Abstract: An embodiment of the disclosure includes a method of forming a semiconductor structure. A substrate has a region adjacent to a shallow trench isolation (STI) structure in the substrate. A patterned mask layer is formed over the substrate. The patterned mask layer covers the STI structure and a portion of the region, and leaves a remaining portion of the region exposed. A distance between an edge of the remaining portion and an edge of the STI structure is substantially longer than 1 nm. The remaining portion of the region is etched thereby forms a recess in the substrate. A stressor is epitaxially grown in the recess. A conductive plug contacting the stressor is formed.
