Abstract: Embodiments of mechanisms for forming dislocations in source and drain regions of finFET devices are provided. The mechanisms involve recessing fins and removing the dielectric material in the isolation structures neighboring fins to increase epitaxial regions for dislocation formation. The mechanisms also involve performing a pre-amorphous implantation (PAI) process either before or after the epitaxial growth in the recessed source and drain regions. An anneal process after the PAI process enables consistent growth of the dislocations in the source and drain regions. The dislocations in the source and drain regions (or stressor regions) can form consistently to produce targeted strain in the source and drain regions to improve carrier mobility and device performance for NMOS devices.

Abstract: 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.

Abstract: A semiconductor structure includes a substrate, a gate structure, and two silicon-containing structures. The substrate includes two recesses defined therein and two doping regions of a first dopant type. Each of the two doping regions extends along a bottom surface and at least portion of a sidewall of a corresponding one of the two recesses. The gate structure is over the substrate and between the two recesses. The two silicon-containing structures are of a second dopant type different from the first dopant type. Each of the two silicon-containing structures fills a corresponding one of the two recesses, and an upper portion of each of the two silicon-containing structures has a dopant concentration higher than that of a lower portion of each of the two silicon-containing structures.
