Claim Text:
1. A method of forming a device comprising: forming a plurality of fins on a substrate; forming source and drain regions in each of the plurality of fins; forming a dielectric layer comprising a first portion, a second portion and a third portion between the fins; adjusting a thickness of the dielectric layer between at least two of the plurality of fins; forming a continuous gate structure on the fins and dielectric layer; and forming a continuous first metal layer overlying the source regions of the plurality of fins, thereby forming a source region of a single finFET device, the single finFET device comprising the plurality of fins, the continuous first metal layer and the continuous gate structure; wherein, after the forming the continuous gate structure, the first portion is between first and second fins of the plurality of fins and has a top surface about level with top surfaces of the first and second fins; wherein, after the forming the continuous gate structure, the second portion is between the second fin and a third fin of the plurality of fins and has a top surface below the top surface of the second fin; wherein, after the forming the continuous gate structure, the third portion is adjacent the third fin opposite the second portion and has a top surface about level with top surfaces of the third fin; and wherein the continuous gate structure is configured to simultaneously control operation of each of the plurality of fins in the single FinFET device.
