Abstract :
This paper describes the integration of Copper with a SiOC/AirGap in a 0.18 μm Double Level Metal Interconnect. A new concept is presented to achieve this ultimate interconnect scheme, and its feasibility is demonstrated by a 55% reduction of the total capacitance measured versus a Cu/SiO2 interconnect
