Claim:
1. A fin-type field effect transistor (finFET) device, comprising: a gate disposed over at least two fins, each fin defining a source outboard portion and a drain outboard portion extending beyond the gate; a source contact electrically connecting the source outboard portions of the fins; a drain contact electrically connecting the drain outboard portions of the fins; a first dielectric spacer layer disposed adjacent to the gate and overlying the fins; a second dielectric spacer layer disposed adjacent to the first dielectric spacer layer and overlying the fins, the second dielectric spacer layer electrically isolating the gate from the drain contact and/or from the source contact; and a cladding layer disposed on sidewalls of the source and drain outboard portions of the fins, said cladding layer underlying the second dielectric spacer layer such that dopant ingress from the cladding layer to the source and drain outboard portions are defined by an overlay capacitance C
