    Abstract: A method of fabricating a semiconductor device is provided. The method forms a fin arrangement on a semiconductor substrate, the fin arrangement comprising one or more semiconductor fin structures. The method continues by forming a gate arrangement overlying the fin arrangement, where the gate arrangement includes one or more adjacent gate structures. The method proceeds by forming an outer spacer around sidewalls of each gate structure. The fin arrangement is then selectively etched, using the gate structure and the outer spacer(s) as an etch mask, resulting in one or more semiconductor fin sections underlying the gate structure(s). The method continues by forming a stress/strain inducing material adjacent sidewalls of the one or more semiconductor fin sections.

    Abstract: Methods for fabricating FinFET structures with stress-inducing source/drain-forming spacers and FinFET structures having such spacers are provided herein. In one embodiment, a method for fabricating a FinFET structure comprises fabricating a plurality of parallel fins overlying a semiconductor substrate. Each of the fins has sidewalls. A gate structure is fabricated overlying a portion of each of the fins. The gate structure has sidewalls and overlies channels within the fins. Stress-inducing sidewall spacers are formed about the sidewalls of the fins and the sidewalls of the gate structure. The stress-inducing sidewall spacers induce a stress within the channels. First conductivity-determining ions are implanted into the fins using the stress-inducing sidewall spacers and the gate structure as an implantation mask to form source and drain regions within the fins.

    Abstract: A method and arrangement for reducing the series resistance of the source and drain in a MOSFET device provides for epitaxially grown regions on top of the source and drain extensions to cover portions of the top surfaces of the silicide regions formed on the substrate. The epitaxial material provides an extra flow path for current to flow through to the silicide from the extension, as well as increasing the surface area between the source/drain and the silicide to reduce the contact resistance between the source/drain and the silicide.
