  • Publication number: 20230299201
    Abstract: A packaged multichip isolation device includes leadframe including a first and second die pad, with a first and second lead extending outside a molded body having a downward extending lead bend near their outer ends. A first integrated circuit (IC) die on the first die pad has a first bond pad connected to the first lead that realizes a transmitter or receiver. A second IC die on the second die pad has a second bond pad connected to the second lead that realizes another of the transmitter and receiver. An isolation component is in a signal path of the isolation device including a capacitive isolator, or inductors for transformer isolation on or between the die. A midpoint of the thickness of the die pad is raised above a top level of the leads and in an opposite vertical direction relative to the downward extending bend of the external leads.

  • Patent number: 11574884
    Abstract: An electronic device includes one or more multinode pads having two or more conductive segments spaced from one another on a semiconductor die. A conductive stud bump is selectively formed on portions of the first and second conductive segments to program circuitry of the semiconductor die or to couple a supply circuit to a load circuit. The multinode pad can be coupled to a programming circuit in the semiconductor die to allow programming a programmable circuit of the semiconductor die during packaging. The multinode pad has respective conductive segments coupled to the supply circuit and the load circuit to allow current consumption or other measurements during wafer probe testing in which the first and second conductive segments are separately probed prior to stud bump formation.

    Abstract: A leadframe includes leads or lead terminals, a plurality of folded features including i) support features positioned within an area defined in at least one dimension by the leads or the lead terminals configured for supporting at least one of a die pad and a first pad and a second pad spaced apart from one another, or ii) current carrying features. At least one of the folded features includes a planar portion and a folded edge structure that curves upwards at an angle of at least 45° relative to the planar portion. The folded features are configured to provide an effective increase in thickness to reduce the deformation observed in assembly.
