  • Publication number: 20230245994
    Abstract: A semiconductor device semiconductor chip mounted to a leadframe that includes an electrically conductive pad. An electrically conductive clip is arranged in a bridge-like position between the semiconductor chip and the electrically conductive pad. The electrically conductive clip is soldered to the semiconductor chip and to the electrically conductive pad via soldering material applied at coupling surfaces facing towards the semiconductor chip and the electrically conductive pad. The device further includes a pair of complementary positioning formations formed by a cavity in the electrically conductive clip and a protrusion (such as a stud bump or a stack of stud bumps) formed in the electrically conductive pad. The complementary positioning formations are mutually engaged to retain the electrically conductive clip in the bridge-like position to avoid displacement during soldering.

  • Publication number: 20230245955
    Abstract: A semiconductor device includes an electrically conductive clip arranged in a bridge-like position between a semiconductor integrated circuit chip and an electrically conductive pad of a leadframe. The electrically conductive clip is soldered to the semiconductor integrated circuit chip and to the electrically conductive pad via soldering material applied at coupling surfaces facing towards the semiconductor integrated circuit chip and the electrically conductive pad. Prior to soldering, the clip is immobilized in the desired bridge-like position via one of welding (such as laser welding) or gluing at dedicated immobilization areas.

  • Publication number: 20220059369
    Abstract: A semiconductor die is attached to a die pad of a leadframe. The semiconductor die attached to the die pad is arranged in a molding cavity between complementary first and second mold portions. Package material is injected into the molding cavity via at least one injection channel provided in one of the complementary first and second mold portions. Air is evacuated from the molding cavity via at least one air venting channel provided in the other of the complementary first and second mold portions. An exit from the at least one air venting channel may be blocked by a retractable stopper during the injection of the package material.

  • Patent number: 9640464
    Abstract: A method for manufacturing a surface-mount electronic device includes making a first partial cut from a bottom of an assembly that includes a first semiconductor body that is disposed on a first die pad, a second semiconductor body that is disposed on a second die pad, and a plurality of terminal regions that is disposed between the first and second die pads. The first partial cut forms a recess by removing a portion of each of the terminal regions. The recess is defined by a transverse wall, a first sidewall, and a second sidewall. The first and second sidewalls and the transverse wall are coated with an anti-oxidation layer. A second partial cut is made from the top, where the second partial cut removes the transverse wall, separates the first and second semiconductor bodies, and has a width that is greater than a width of the first partial cut.
