  • Patent number: 11443879
    Abstract: An integrated magnetic device has a magnetic core which includes layers of the magnetic material located in a trench in a dielectric layer. The magnetic material layers are flat and parallel to a bottom of the trench, and do not extend upward along sides of the trench. The integrated magnetic device is formed by forming layers of the magnetic material over the dielectric layer and extending into the trench. A protective layer is formed over the magnetic material layers. The magnetic material layers are removed from over the dielectric layer, leaving the magnetic material layers and a portion of the protective layer in the trench. The magnetic material layers along sides of the trench are subsequently removed. The magnetic material layers along the bottom of the trench provide the magnetic core.

  • Publication number: 20160148883
    Abstract: A method of forming bond pads includes providing a substrate including an integrated circuit (IC) device formed thereon having an oxidizable uppermost metal interconnect layer which provides a plurality of bond pads that are coupled to circuit nodes on the IC device. The plurality of bond pads include a metal bond pad area. At least one passivation layer provides a trench including dielectric sidewalls above the metal bond pad area. A ruthenium (Ru) layer is deposited directly on the dielectric sidewalls and directly on the metal bond pad area, which removes the need for a barrier layer lining the dielectric sidewalls of the trench. The Ru layer is patterned to provide a bond pad surface for the plurality of bond pads.

  • Publication number: 20050075055
    Abstract: Light is incident on a semiconductor wafer polish surface and an adjacent reference surface (80). The reflected light from each surface is detected by a detector (35) positioned beneath the surfaces. The signals derived from each source of reflected light is analyzed in a electronic system (37) and an endpoint for a chemical mechanical polish process is determined as a function of both signals.
