Abstract:
Embodiments of the present disclosure are directed towards metallization of a fluorocarbon-based dielectric material for interconnect applications. In one embodiment, an apparatus includes a semiconductor substrate, a device layer disposed on the semiconductor substrate, the device layer including one or more transistor devices, and an interconnect layer disposed on the device layer, the interconnect layer comprising a fluorocarbon-based dielectric material, where x represents a stoichiometric quantity of fluorine relative to carbon in the dielectric material, and one or more interconnect structures configured to route electrical signals to or from the one or more transistor devices, the one or more interconnect structures comprising cobalt (Co), or ruthenium (Ru), or combinations thereof. Other embodiments may be described and/or claimed.
