  • Micro-electro-mechanical system (MEMS) structure and design structures
    Patent number: 9496110
    Abstract: Micro-Electro-Mechanical System (MEMS) structures, methods of manufacture and usage, and design structures are disclosed herein. The method includes applying a first voltage polarity to an actuator of a Micro-Electro-Mechanical System (MEMS) structure to place the MEMS structure in a predetermined state for a first operating condition. The method further includes applying a second voltage polarity which is opposite from the first voltage polarity to the actuator of the MEMS structure during a subsequent operating condition.
    Type: Grant
    Filed: June 18, 2013
    Date of Patent: November 15, 2016
    Assignee: GLOBALFOUNDRIES INC.
    Inventors: Ward A. Johnson, Jenifer E. Lary, Anthony K. Stamper, Kimball M. Watson, Pui L. Yee
  • Alleviation of the corrosion pitting of chip pads
    Patent number: 9159556
    Abstract: Methods for processing a metal pad of a chip and chip structures including a chip with a metal pad. A surface modification agent is applied to the metal pad on the chip. The surface modification agent is effective to increase the hydrophobicity of the metal pad and may involve silylation.
