  • Publication number: 20230095545
    Abstract: A semiconductor package includes a leadframe including a diepad and a first row of leads, wherein at least one lead of the first row of leads is physically separated from the diepad by a gap. The semiconductor package further includes a semiconductor component arranged on the leadframe. The semiconductor package further includes an encapsulation material encapsulating the leadframe and the semiconductor component, wherein the encapsulation material includes a bottom surface arranged at a bottom surface of the semiconductor package, a top surface and a side surface extending from the bottom surface to the top surface. A side surface of at least one lead of the first row of leads is flush with the side surface of the encapsulation material. The flush side surface of the at least one lead is covered by an electroplated metal coating.

  • Patent number: 11239127
    Abstract: A molded semiconductor package arrangement may comprise a die pad configured to support a semiconductor; a set of leads; and a mold structure that is formed to enclose the semiconductor and the die pad within the mold structure. The set of leads and the die pad may be formed from a same piece of conductive material. An electrical contact plane of the set of leads may be offset from a bottom surface of the die pad. The mold structure may include a molded standoff that is beneath the die pad. A bottom surface of the molded standoff may extend below the electrical contact plane of the set of leads by a threshold distance that corresponds to a thickness of the molded standoff.

  • Patent number: 11183451
    Abstract: An interconnect clip includes a die contact portion having substantially planar upper and lower surfaces that are parallel to and opposite from one another, a bridge portion adjoining the die contact portion and having substantially planar upper and lower surfaces that are parallel to and opposite from one another, a lead contact portion adjoining the bridge portion and having a lead contact surface or contact point, and a bridge portion adjoining the die contact portion and having substantially planar upper and lower surfaces that are parallel to and opposite from one another. The lower surface of the die contact portion extends along a first plane. The lower surface of the bridge portion extends along a second plane that is completely above the first plane throughout a complete length of the bridge portion. The lead contact surface or contact point is disposed below the first plane.
