Abstract

The present disclosure provides semiconductor devices and methods of forming the same. A semiconductor device according to one embodiment of the present disclosure includes a first fin-shaped structure extending lengthwise along a first direction over a substrate, a first epitaxial feature over a source/drain region of the first fin-shaped structure, a gate structure disposed over a channel region of the first fin-shaped structure and extending along a second direction perpendicular to the first direction, and a source/drain contact over the first epitaxial feature. The bottommost surface of the gate structure is closer to the substrate than a bottommost surface of the source/drain contact.
