Abstract

An integrated circuit (IC) with a semiconductor device and an interconnect structure with carbon layers and methods of fabricating the same are disclosed. The method includes forming a fin structure on a substrate, forming a source/drain region on the fin structure, forming a contact structure on the S/D region, forming an oxide layer on the contact structure, forming a conductive carbon line within a first insulating carbon layer on the oxide layer, forming a second insulating carbon layer on the first insulating carbon layer, and forming a via within the second insulating carbon layer.
