  • Patent number: 11380612
    Abstract: In an embodiment, a semiconductor device includes a galvanically isolated signal transfer coupler having a contact pad. The contact pad includes a metallic base layer, a metallic diffusion barrier layer arranged on the metallic base layer, and a metallic wire bondable layer arranged on the metallic diffusion barrier layer. The metallic diffusion barrier layer includes a first portion and a second portion. The first portion has a first surface and a second surface opposing the first surface. The first surface has a curved surface at the periphery. The first portion extends in a transverse plane and has a width. The second portion protrudes from the second surface intermediate the width of the first portion.

  • Patent number: 10090192
    Abstract: A method for producing a rounded conductor line of a semiconductor component is disclosed. In that method, a partially completed semiconductor component is provided. The partially completed semiconductor component has a bottom side and a top side spaced distant from the bottom side in a vertical direction. Also provided is an etchant. On the top side, a dielectric layer is arranged. The dielectric layer has at least two different regions that show different etch rates when they are etched with the etchant. Subsequently, a trench is formed in the dielectric layer such that the trench intersects each of the different regions. Then, the trench is widened by etching the trench with the etchant at different etch rates. By filling the widened trench with an electrically conductive material, a conductor line is formed.

  • Patent number: 9598277
    Abstract: Embodiments relate to MEMS devices and methods for manufacturing MEMS devices. In one embodiment, the manufacturing includes forming a monocrystalline sacrificial layer on a non-silicon-on-insulator (non-SOI) substrate, patterning the monocrystalline sacrificial layer such that the monocrystalline sacrificial layer remains in a first portion and is removed in a second portion lateral to the first portion; depositing a first silicon layer, the first silicon layer deposited on the remaining monocrystalline sacrificial layer and further lateral to the first portion; removing at least a portion of the monocrystalline sacrificial layer via at least one release aperture in the first silicon layer to form a cavity and sealing the cavity.

  • Patent number: 9145292
    Abstract: Embodiments relate to MEMS devices, particularly MEMS devices integrated with related electrical devices on a single wafer. Embodiments utilize a modular process flow concept as part of a MEMS-first approach, enabling use of a novel cavity sealing process. The impact and potential detrimental effects on the electrical devices by the MEMS processing are thereby reduced or eliminated. At the same time, a highly flexible solution is provided that enables implementation of a variety of measurement principles, including capacitive and piezoresistive. A variety of sensor applications can therefore be addressed with improved performance and quality while remaining cost-effective.
