Patent ID: 7091594

Claim:
A semiconductor package comprising: a heat sink having opposed top and bottom surfaces and defining a peripheral edge; a semiconductor die attached to the top surface of the heat sink; a plurality of leads extending at least partially about the semiconductor die, the semiconductor die being electrically connected to at least one of the leads; at least one first ground lead attached to the top surface of the heat sink between the semiconductor die and the peripheral edge of the heat sink; at least one second ground lead attached to the top surface of the heat sink and protruding beyond the peripheral edge thereof; a plurality of ground wires conductively connecting the semiconductor die, the first and second ground leads, and the heat sink to each other; and a package body at least partially encapsulating the heat sink, the semiconductor die, the leads, the first and second ground leads, and the ground wires such that at least portions of the second ground lead and the leads are exposed in the package body.
