Abstract: A layer of carbon (e.g., graphite or graphene) at a metal interface (e.g., between an MEOL interconnect and a gate contact or a source or drain region contact, between an MEOL contact plug and a BEOL metallization layer, and/or between BEOL conductive structures) is used to reduce contact resistance at the metal interface, which increases electrical performance of an electronic device. Additionally, in some implementations, the layer of carbon may help prevent heat transfer from a second metal to a first metal when the second metal is deposited over the first metal. This results in more symmetric deposition of the second metal, which reduces surface roughness and contact resistance at the metal interface. As an alternative, in some implementations, the layer of carbon is etched before deposition of the second metal in order to reduce contact resistance at the metal interface.
