CHIEN-KANG HSIUNG 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: 11587799
    Abstract: Methods and apparatus for processing a substrate are provided herein. For example, the method can include depositing a first layer of metal on a first substrate; depositing a second layer of metal atop the first layer of metal; depositing a third layer of metal on a second substrate; depositing a fourth layer of metal atop the third layer of metal; and bringing the second layer of material into contact with the fourth layer of material under conditions sufficient to cause the first substrate to be bonded to the second substrate by a diffusion layer formed by portions of the first layer of metal diffusing through the second layer of metal and portions of the third layer of metal diffusing through the fourth layer of metal.
    Type: Grant

    Date of Patent: February 21, 2023
    Assignee: APPLIED MATERIALS, INC.
    Inventors: Chien-Kang Hsiung, Yuichi Wada, Glen T. Mori
  • Publication number: 20220181142
    Abstract: Methods and apparatus for far edge trimming are provided herein. For example, an apparatus includes an integrated tool for processing a silicon substrate, comprising a vacuum substrate transfer chamber, an edge trimming apparatus coupled to the vacuum substrate transfer chamber and comprising a high pulse frequency laser and substrate support, wherein at least one of the high pulse frequency laser or the substrate support are movable with respect to each other and configured to trim about 2 mm to about 5 mm from a peripheral edge of a substrate when disposed on the substrate support, and a plasma etching apparatus coupled to the vacuum substrate transfer chamber and configured to etch silicon.

  • Patent number: 10651126
    Abstract: A wafer-level bridge die is affixed with an adhesive layer to a redistribution layer (RDL) that has been temporarily bonded to a carrier. Electrical interconnects are formed on the RDL and on the bridge die and encapsulated in a first mold layer. A plurality of dies are coupled to the RDL and the bridge die such that a die is electrically connected to at least one electrical interconnect of the RDL and to at least one electrical interconnect of the bridge die. A second mold layer is formed on the first mold layer to encapsulate the plurality of dies. The temporary bond is then broken and the carrier is removed, exposing the RDL connections.
