Patent ID: 6881996

Claim:
A metal-insulator-metal (MIM) capacitors for CMOS circuits on a semiconductor substrate comprised of: a semiconductor substrate having partially completed CMOS circuits including several layers of metal interconnections; a first insulating layer having recesses for capacitor bottom metal (CBM) electrodes, pad contacts, and a level of metal interconnections; copper in said recesses that form CBM electrodes, pad contacts, and a level of metal interconnections; an insulating protecting buffer layer and a second insulating layer over said CBM electrodes that serves as a portion of an interelectrode dielectric layer; a conducting metal protect buffer layer on said second insulating layer; a patterned titanium nitride/aluminum copper/titanium nitride blanket pad protection metal layer to form capacitor top metal (CTM) electrodes, pad protection on said pad contacts, and next level of metal interconnecting lines; a passivating third insulating layer having openings to said pad protection over said pads and to said CTM electrodes.
