Claim Text:
1. A fin field-effect transistor (FinFET) device, comprising: a substrate; a plurality of fins on the substrate; a plurality of gate regions on portions of the fins, wherein the gate regions are spaced apart from each other; spacers on each respective gate region; one or more contact area trenches respectively formed at one or more portions between adjacent gate regions; an epitaxy region on each of the fins in the one or more contact area trenches, wherein the epitaxy regions on adjacent fins in the one or more contact area trenches are merged with each other to form merged epitaxy regions; and an unmerged epitaxy region on portions of each of the fins between the one or more contact area trenches; wherein the unmerged epitaxy regions are doped differently than the merged epitaxy regions.
