  • Patent number: 9818688
    Abstract: Structures and methods of making a dielectric region in a bulk silicon (Si) substrate of a mixed-signal integrated circuit (IC) provide a high-Q passive resonator. Deep trenches within the bulk Si substrate in <100> directions are expanded by wet etching to form contiguous cavities, which are filled by Si oxide to form a dielectric region. The dielectric region enhances the quality (Q) of an overlying passive resonator, formed in metallization layers of the mixed-signal IC.

  • Patent number: 9703036
    Abstract: Disclosed are structures with an optical waveguide having a first segment at a first level and a second segment extending between the first level and a higher second level and further extending along the second level. Specifically, the waveguide comprises a first segment between first and second dielectric layers. The second dielectric layer has a trench, which extends through to the first dielectric layer and which has one side positioned laterally adjacent to an end of the first segment. The waveguide also comprises a second segment extending from the bottom of the trench on the side adjacent to the first segment up to and along the top surface of the second dielectric layer on the opposite side of the trench. A third dielectric layer covers the second segment in the trench and on the top surface of the second dielectric layer. Also disclosed are methods of forming such optoelectronic structures.

  • Patent number: 9524924
    Abstract: An approach to creating a semiconductor structure for a dielectric layer over a void area includes determining a location of a void area of the topographical semiconductor feature. A second dielectric layer is deposited on a first dielectric layer and a top surface of a topographical semiconductor feature. The second dielectric layer is patterned to one or more portions, wherein at least one portion of the patterned second dielectric layer is over the location of the void area of the topographical semiconductor feature. A first metal layer is deposited over the second dielectric layer, at least one portion of the first dielectric layer, and a portion of the top surface of the topographical semiconductor feature. A chemical mechanical polish of the first metal layer is performed, wherein the chemical mechanical polish reaches the top surface of at least one of the one or more portions of the second dielectric layer.
