Abstract
The present disclosure provides an integrated circuit (IC) device, including: a semiconductor substrate having a top surface; a first source/drain feature and a second source/drain feature disposed on the semiconductor substrate; and a plurality of semiconductor layers including a first semiconductor layer and a second semiconductor layer. Each of the first semiconductor layer and the second semiconductor layer extends longitudinally in a first direction and connects the first source/drain feature and the second source/drain feature. The first semiconductor layer is stacked over the second semiconductor layer in a second direction perpendicular to the first direction. A length of the first semiconductor layer along the first direction is less than a length of the second semiconductor layer along the first direction. The IC device further includes a gate structure engaging center portions of the first semiconductor layer and the second semiconductor layer.
