Abstract: A semiconductor package includes a semiconductor chip, a die pad being mounted with the semiconductor chip with a dielectric interposed therebetween and serving as an antenna, and a molding resin (sealing resin) sealing the semiconductor chip and the die pad. The relative dielectric constant of the dielectric is higher than that of the sealing resin.

Abstract: A lead frames has a forked top portion which has a recessed portion adjusted for receipt of a wire so that the wire is so caught by the forked top portion as to prevent the wire from being largely carried. Even if the density of the wires is high, the wires are not carried by the flow of the molten resin so that the wires are kept from contact with each other thereby avoiding short circuits. At the corners, the distance of the adjacent two wires is narrower than the other positions. Notwithstanding, the wires at the corners are also prevented by the forked top portion of the lead frame from being largely carried by the flow of the molten resin so that the wires are kept from contact with each other thereby avoiding short circuit.

Abstract: In an apparatus for manufacturing a semiconductor device, insulator is sprayed to a bonding wire continuously fed from a capillary immediately after a first bonding to coat the bonding wire with the insulator. The spray is stopped immediately before the capillary reaches a second bonding position. Then, a second bonding is performed when the capillary reaches the second bonding position.
