Mohd Hasrul Zulkifli 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: 11769748
    Abstract: A semiconductor device includes a semiconductor die attached to a substrate and a metal clip attached to a side of the semiconductor die facing away from the substrate by a soldered joint. The metal clip has a plurality of slots dimensioned so as to take up at least 10% of a solder paste that reflowed to form the soldered joint. Corresponding methods of production are also described.
    Type: Grant
    Filed: December 1, 2022
    Date of Patent: September 26, 2023
    Assignee: Infineon Technologies AG
    Inventors: Thomas Stoek, Michael Stadler, Mohd Hasrul Zulkifli
  • Patent number: 11676881
    Abstract: A semiconductor package is disclosed. In one example, the semiconductor package includes a chip carrier, a semiconductor chip attached to the chip carrier, an encapsulation body encapsulating the semiconductor chip, and a mounting hole configured to receive a screw for screw mounting a heatsink onto a first side of the semiconductor package. A second side of the semiconductor package opposite the first side is configured to be surface mounted to an application board.

  • Patent number: 11355424
    Abstract: A package includes a package body with a package top side, package footprint side and package sidewalls extending from the package footprint side to the package top side; power semiconductor chips electrically connected in parallel and each having first and second load terminals and being configured to block a blocking voltage and conduct a chip load current between the load terminals; a lead frame structure configured to electrically and mechanically couple the package to a carrier with the package footprint side facing the carrier, the lead frame structure including first outside terminals extending out of the package body for interfacing with the carrier. Each first load terminal is electrically connected, at least by one package body internal connection member, to at least two of the first outside terminals. A horizontally extending conduction layer at the package top side or footprint side is electrically connected with each second load terminal.

  • Publication number: 20220139811
    Abstract: An interconnect clip includes a die attach pad that comp includes rises a die attach surface at an inner side of the interconnect clip, a heat dissipation pad that includes a heat dissipation surface at an outer side of the interconnect clip, and a lead contact pad that includes a lead contact surface at an inner side of the interconnect clip or at an outer side of the interconnect clip. The outer side of the interconnect clip in the lead contact pad faces and is spaced apart from the inner side of the interconnect clip in the heat dissipation pad, and the inner side of the interconnect clip in the lead contact pad faces and is spaced apart from the outer side of the interconnect clip in the die attach pad.
