Patents by Inventor JAMES E. HISERT

JAMES E. HISERT has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11766721
    Abstract: Implementations of the disclosure are directed to thermally decomposable build plates that enable the facile release of 3D metal printed parts created by additive manufacturing. In some implementations, an additive manufacturing build plate comprises: a top surface, a bottom surface, and sidewalls comprised of a material, wherein the top surface, bottom surface, and sidewalls are dimensioned such that the build plate is useable in a 3D printing device; and a recessed section formed through the top surface, wherein the recessed section is configured to be filled with a solid metal or metal alloy to provide a surface for forming a 3D printed object in the 3D printing device.
    Type: Grant

  • Patent number: 10943795
    Abstract: A method of joining a semiconductor die to a passive heat exchanger can include applying a bond enhancing agent to a semiconductor device; creating an assembly that includes a thermal interface disposed on the semiconductor device such that a first major surface of the thermal interface material is in touching relation with the bond enhancing agent on the semiconductor device, and a heat exchanger disposed in touching relation with a second major surface of the thermal interface material; and reflowing the assembly such that the thermal interface bonds the heat exchanger to the semiconductor device. Embodiments can use the ability of indium to bond to a non-metallic surface to form the thermal interface, which may be enhanced by a secondary coating on either or both joining surfaces.

  • Patent number: 10943796
    Abstract: A semiconductor device assembly includes: a semiconductor device; a heat exchanger; and a thermal interface material. In embodiments, the thermal interface material may contact a facing surface of the heat exchanger, the thermal interface material includes alloys that react with a bond enhancing agent to form an indium alloy layer in a portion of the thermal interface. In embodiments, a solid, solder preformed thermal interface material includes an indium metal and may be disposed on the first surface of the semiconductor device; and a liquid metal bond enhancing agent may be disposed on a first surface of the semiconductor device; and contacting a facing surface of the heat exchanger.
