  • MEMS devices and processes
    Patent number: 10623852
    Abstract: The application relates to MEMS transducers comprising at least one support structure for connecting a backplate structure of the transducer with an underlying substrate. A strengthening portion is provided in the region of the support structure.
    Type: Grant
    Filed: October 3, 2018
    Date of Patent: April 14, 2020
    Assignee: Cirrus Logic, Inc.
    Inventors: Scott Lyall Cargill, Timothy John Brosnihan
  • MEMS devices and processes
    Patent number: 10450189
    Abstract: The application describes a MEMS transducer comprising a substrate having a cavity. The transducer exhibits a membrane layer supported relative to the substrate to define a flexible membrane. An upper surface of the substrate comprises an overlap region between the edge of the cavity and a perimeter of the flexible membrane where the membrane overlies the upper surface of the substrate. At least one portion of the overlap region of the upper surface of the substrate is provided with a plurality of recesses. The recesses are defined so as to extend from the edge of the cavity towards the perimeter of the flexible membrane.
    Type: Grant
