Abstract:
A semiconductor device includes a gate structure located on a substrate; and a raised source/drain region adjacent to the gate structure. An interface is between the gate structure and the substrate. The raised source/drain region includes a stressor layer providing strain to a channel under the gate structure; and a silicide layer in the stressor layer. The silicide layer extends from a top surface of the raised source/drain region and ends below the interface by a predetermined depth. The predetermined depth allows the stressor layer to maintain the strain of the channel.

Claim (Index 15):
A method for manufacturing a semiconductor device comprising:\n providing a substrate including a gate structure on the substrate; forming a cavity in the substrate and adjacent to the gate structure by an etching process; epitaxially growing a first layer in the cavity; epitaxially growing a second layer on the first layer; epitaxially growing a third layer on the second layer; and forming a silicide layer penetrating a top surface of the third layer and extending into at least the second layer, and the silicide layer being partially below an interface between the gate structure and the substrate by a predetermined depth.
