US Patent 7550773 FinFET with top body contact

FinFETs are provided with a body contact on a top surface of a semiconductor fin. The top body contact may be self-aligned with respect to the semiconductor fin and the source and drain regions. Alternately, the source and drain regions may be formed recessed from the top surface of the semiconductor fin. The body or an extension of the body may be contacted above the channel or above one of the source and drain regions. Electrical shorts between the source and drain and the body contacts are avoided by the recessing of the source and drain regions from the top surface of the semiconductor fin.
