Abstract
An interconnection wiring system incorporating two levels of interconnection wiring separated by a first dielectric, a capacitor formed by a second dielectric, a bottom electrode of the lower interconnection wiring or a via and a top electrode of the upper interconnection wiring or a separate metal layer. The invention overcomes the problem of leakage current and of substrate stray capacitance by positioning the capacitor between two levels of interconnection wiring.
