Abstract
A three-dimensional transistor includes a semiconductor substrate, a fin coupled to the substrate, the fin including an active region across a top portion thereof, the active region including a source, a drain and a channel region therebetween. The transistor further includes a gate situated above the channel region, and a gate contact situated in the active region, no portion thereof being electrically coupled to the source or drain. The transistor is achieved by removing a portion of the source/drain contact situated beneath the gate contact during fabrication.
