Abstract
A semiconductor device and methods of fabricating the same are disclosed. The method can include forming a fin structure on a substrate, forming a source/drain (S/D) region on the fin structure, forming a gate structure on the fin structure adjacent to the S/D region, and forming a capping structure on the gate structure. The forming the capping structure includes forming a conductive cap on the gate structure, forming a cap liner on the conductive cap, and forming a carbon-based cap on the cap liner. The method further includes forming a first contact structure on the S/D region, forming an insulating cap on the first contact structure, and forming a second contact structure on the conductive cap.
