A new damascene architecture for high-performance metalinsulatormetal capacitors integration
As high-performance metalinsulatormetal capacitors are required for new technologies, an innovative architecture was developed with standard damascene processes used for copper interconnect realization. Low-cost damascene capacitors were integrated with thin Si3N4 films, leading to 2.9 fF/?m2 capacitance values and low leakage currents, demonstrating this architecture ability to reduce the insulators thickness, thus achieving high-performance passive implementation for mixed integrated circuits.
