Abstract
A semiconductor includes a semiconductor substrate, a gate stack on the semiconductor substrate, and a stressor having at least a portion in the semiconductor substrate and adjacent to the gate stack. The stressor includes a first stressor region and a second stressor region on the first stressor region, wherein the second stressor region extends laterally closer to a channel region underlying the gate stack than the first stressor region.
