摘要:
A method includes forming a gate stack over a semiconductor region, and recessing the semiconductor region to form a recess adjacent the gate stack. A silicon-containing semiconductor region is epitaxially grown in the recess to form a source/drain stressor. Arsenic is in-situ doped during the step of epitaxially growing the silicon-containing semiconductor region.
