  • Publication number: 20200294896
    Abstract: A packaged semiconductor device includes a die paddle, a semiconductor die mounted on the die paddle, a plurality of fused leads extending away from a first side of the die paddle, a discrete lead that extends away from the first side of the die paddle and is physically detached from the plurality of fused leads, a first electrical connection between a first terminal of the semiconductor die and the discrete lead, an encapsulation material that encapsulates the semiconductor die, and a stabilizer bar connected to a first outer edge side of the discrete lead. The first outer edge side of the discrete lead is opposite from a second outer edge side of the discrete lead which faces the plurality of fused leads.

  • Patent number: 10424534
    Abstract: A semiconductor device includes a lead frame including a die paddle and a lead, a semiconductor chip, and a clip. The semiconductor chip has a first side and a second side opposite to the first side. The first side is attached to the die paddle and the second side includes a first bond pad and a second bond pad. The clip electrically couples the first bond pad to the lead. The clip contacts the first bond pad at a first edge portion of the first bond pad adjacent to the second bond pad and defines a first cavity between a central portion of the first bond pad and the clip. Solder is within the first cavity to electrically couple the clip to the first bond pad. The semiconductor device includes a first opening to the first cavity to route flux away from the second bond pad during reflow soldering.
