Abstract
Embodiments of the present disclosure provide semiconductor device structures and methods of forming the same. The structure includes a semiconductor layer disposed over a substrate, and the semiconductor layer has a first end and a second end opposite the first end. The structure further includes an epitaxial feature disposed over the substrate, and the epitaxial feature is electrically connected to the first end of the semiconductor layer. The structure further includes a first dielectric layer disposed over the substrate, and the first dielectric layer is in contact with the second end of the semiconductor layer. The structure further includes a contact etch stop layer disposed on and in contact with the first dielectric layer and an interlayer dielectric layer disposed on and in contact with the contact etch stop layer.
