  • Patent number: 9859205
    Abstract: A semiconductor device and a method of forming an airbridge extending from a conductive area of the semiconductor device are provided. The semiconductor device includes a device pattern formed on a semiconductor substrate, a seed layer formed on the device pattern, and an airbridge formed on the seed layer, where the airbridge includes a plated conductive material and defines an opening exposing a portion of the device pattern. The semiconductor device further includes an adhesion layer formed on the airbridge layer and extending over at least a portion of sidewalls of the opening defined by the airbridge, and an insulating layer formed on the adhesion layer, where the adhesion layer enhances adhesion of the insulating layer to the plated conductive material of the airbridge.
    Type: Grant
    Filed: November 24, 2014
    Date of Patent: January 2, 2018

  • Patent number: 8962443
    Abstract: A method of forming a device having an airbridge on a substrate includes forming a plated conductive layer of the airbridge over at least a photoresist layer on a portion of the substrate, the plated conductive layer defining a corresponding opening for exposing a portion of the photoresist layer. The method further includes undercutting the photoresist layer to form a gap in the photoresist layer beneath the plated conductive layer at the opening, and forming an adhesion layer on the plated conductive layer and the exposed portion of the photoresist layer, the adhesion layer having a break at the gap beneath the plated conductive layer. The photoresist layer and a portion of the adhesion layer formed on the exposed portion of the photoresist layer is removed, which includes etching the photoresist layer through the break in the adhesion layer. An insulating layer is formed on at least the adhesion layer, enhancing adhesion of the insulating layer to the plated conductive layer.

  • Patent number: 4992840
    Abstract: A MOSFET device having a near-micrometer or submicrometer channel length and designed to operated under conditions that cause generation of hot carriers is carbon doped in the silicon substrate at the gate oxide-silicon interface. The oxide-silicon interface can include hydrogen atoms. These atoms are mostly bonded to carbon atoms, more strongly than hydrogen bonds to silicon, so that hot carriers are less likely to dissociate the hydrogen atoms and form hot carrier trapping sites at the interface. Hot carrier aging is thus substantially reduced. This capability is particularly useful in submicrometer devices, avoiding need to reduce normal operating voltages.

  • Patent number: 4566193
    Abstract: An electronic vernier is presented which detects and quantifies misalignment between layers of material deposited upon a semiconducting wafer. Verniers may be constructed which evaluate alignment between two conducting layers, between two conducting layers and an insulating layer and between a semiconducting layer and a capacitive layer. Circuitry is described which shows how output from a vernier may be detected and quantified in order to evaluate the amount of misalignment.
