  • Multiple electrode layer backend stacked capacitor
    Patent number: 8497565
    Abstract: In a disclosed embodiment, a stacked capacitor (100) has bottom, middle and top metal electrode layers (141A, 141B, 141C) interleaved with dielectric layers (142A, 142B) conformally disposed within holes (140A, 140B, 140C) in a protective overcoat or backend dielectric layer (110) over a top metal layer (115) of an integrated circuit (105). A top electrode (155) contacts the top metal electrode layer (141C). A bottom electrode (150) electrically couples an isolated part of the top metal electrode layer (141C) through a bottom electrode via (165A) to a first contact node (135A) in the top metal layer (115) which is in contact with the bottom metal electrode layer (141A). A middle electrode (160) electrically couples a part of the middle metal electrode layer (141B) not covered by the top metal layer (115) through a middle electrode via (165B) to a second contact node (135B) in the top metal electrode layer (115).
