  • Patent number: 9583558
    Abstract: A microelectronic device contains a high voltage component having a high voltage node and a low voltage node. The high voltage node is isolated from the low voltage node by a main dielectric between the high voltage node and low voltage elements at a surface of the substrate of the microelectronic device. A lower-bandgap dielectric layer is disposed between the high voltage node and the main dielectric. The lower-bandgap dielectric layer contains at least one sub-layer with a bandgap energy less than a bandgap energy of the main dielectric. The lower-bandgap dielectric layer extends beyond the high voltage node continuously around the high voltage node. The lower-bandgap dielectric layer has an isolation break surrounding the high voltage node at a distance of at least twice the thickness of the lower-bandgap dielectric layer from the high voltage node.

  • Publication number: 20160300907
    Abstract: Isolator structures for an integrated circuit with reduced effective parasitic capacitance. Disclosed embodiments include an isolator structure with parallel conductive elements forming a capacitor or inductive transformer, overlying a semiconductor structure including a well region of a first conductivity type formed within an tank region of a second conductivity type. The tank region is surrounded by doped regions and a buried doped layer of the first conductivity type, forming a plurality of diodes in series to the substrate. The junction capacitances of the series diodes have the effect of reducing the parasitic capacitance apparent at the isolator.

  • Patent number: 8431463
    Abstract: A method is disclosed for passivating and contacting a capacitor in an IC above a top level of interconnect metallization, without adding process steps. Passivation is accomplished by a dielectric layer, part of the IC protective overcoat, deposited directly on the capacitor, overlapping the electrode edges. Contact is made to the top electrode of the capacitor by etching small capacitor vias during a bond pad via etch process, followed by depositing and patterning bond pad metal in the capacitor vias to connect the top electrode to other circuit elements in the IC. The top electrode thickness is increased to accommodate the bond pad via etch process.

    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).
