  • Laser ashing of polyimide for semiconductor manufacturing
    Patent number: 9865564
    Abstract: A system for laser ashing of polyimide for a semiconductor manufacturing process is provided. The system includes: a semiconductor chip, a top chip attached to the semiconductor chip by a connection layer, a supporting material, a polyimide glue layer disposed between the supporting material and semiconductor chip, a plasma asher, and an ashing laser configured to ash the polyimide glue on the semiconductor chip.
    Type: Grant
    Filed: February 18, 2015
    Date of Patent: January 9, 2018
    Assignee: GLOBALFOUNDRIES INC

  • Portable, refrigerant-based apparatus and method for rapid systemic patient cooling
    Patent number: 8491644
    Abstract: A portable patient cooling apparatus is provided that includes a self-contained refrigerator and on-board power storage supply for stand alone operation. The apparatus is interconnectable to one or more heat exchange devices (e.g. patient contact pads or intravascular catheters) through which a cooled fluid may be circulated for patient cooling. Such fluid may be liquid contained within a reservoir comprising the apparatus during periods of non-use. The apparatus preferably defines a total volume of less than about 0.04 m3, while having a total weight of less than about 15 kg to yield a total circulated fluid cooling capacity of at least 200 watts.
