    摘要： An integrated circuit includes a gate electrode disposed over a substrate. A source/drain (S/D) region is disposed adjacent to the gate electrode. The S/D region includes a diffusion barrier structure disposed in a recess of the substrate. The diffusion barrier structure includes a first portion and a second portion. The first portion is adjacent to the gate electrode. The second portion is distant from the gate electrode. An N-type doped silicon-containing structure is disposed over the diffusion barrier structure. The first portion of the diffusion barrier structure is configured to partially prevent N-type dopants of the N-type doped silicon-containing structure from diffusing into the substrate. The second portion of the diffusion barrier structure is configured to substantially completely prevent N-type dopants of the N-type doped silicon-containing structure from diffusing into the substrate.

    摘要： A system and method for manufacturing multiple-gate semiconductor devices is disclosed. An embodiment comprises multiple fins, wherein intra-fin isolation regions extend into the substrate less than inter-fin isolation regions. Regions of the multiple fins not covered by the gate stack are removed and source/drain regions are formed from the substrate so as to avoid the formation of voids between the fins in the source/drain region.

    摘要： A method includes forming first and second fins of a finFET extending above a semiconductor substrate, with a shallow trench isolation (STI) region in between, and a distance between a top surface of the STI region and top surfaces of the first and second fins. First and second fin extensions are provided on top and side surfaces of the first and second fins above the top surface of the STI region. Material is removed from the STI region, to increase the distance between the top surface of the STI region and top surfaces of the first and second fins. A conformal stressor dielectric material is deposited over the fins and STI region. The conformal dielectric stressor material is reflowed, to flow into a space between the first and second fins above a top surface of the STI region, to apply stress to a channel of the finFET.
