A device includes first and second fins defined in a semiconductor substrate and a raised isolation post structure positioned between the first and second fins, wherein an upper surface of the raised isolation post structure is at a level that is approximately equal to or greater than a level corresponding to an upper surface of each of the first and second fins. A first space is defined by a sidewall of the first fin and a first sidewall of the raised isolation post structure, a second space is defined by a sidewall of the second fin and a second sidewall of the raised isolation post structure, and a gate structure is positioned around a portion of each of the first and second fins and around a portion of the raised isolation post structure, wherein at least portions of the gate structure are positioned in the first and second spaces.
