An integrated circuit includes a complimentary field effect transistor (CFET). The CFET includes a first transistor having a first semiconductor nanostructure corresponding to a channel region of the first semiconductor nanostructure and a first gate metal surrounding the second semiconductor nanostructure. The CFET includes a transistor including a second semiconductor nanostructure above the first semiconductor nanostructure and a second gate metal surrounding the second semiconductor nanostructure. The CFET includes an isolation structure between the first and second semiconductor nanostructures.

Complementary field effect transistor with hybrid nanostructure

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.
