Abstract: A lead frame structure comprises a side rail, a first paddle, a second paddle, a plurality of leads, and an downset anchor bar. The first paddle is connected to the side rail via at least one first tie bar, and the second paddle is connected to the side rail via at least one-second tie bar. The first paddle and the second paddle separated from each other are used to define an area to support a chip. These leads set on the side rail expends toward to the chip supporting area. One end of the downset anchor bar is connected to the side rail, and the other end of the downset anchor bar has a protrusion portion which is between the first paddle and the second paddle and is downset from the side rail.

Abstract: A package structure includes a lead frame having a plurality of leads, each of which includes a first recession, at least a first device, and a plurality of solder joints respectively positioned in the first recessions for connecting the first device to the lead frame.

Abstract: In a semiconductor device, a semiconductor chip is mounted on an inner seat body of a heat-dissipating frame mounted on a top surface of a dielectric substrate. Each of multiple bonding wires interconnects electrically one of multiple contact pads on the semiconductor chip and a corresponding one of multiple first conductive contacts on the top surface of the substrate so as to establish electrical connection between the contact pads on the semiconductor chip and multiple second conductive contacts on a bottom surface of the substrate via the first conductive contacts and circuit traces of the substrate. An encapsulant encapsulates the bonding wires, the semiconductor chip, and the inner seat body, a portion of an outer frame body of the heat-dissipating frame, and multiple that interconnect portions interconnecting heat-conductively the inner seat body and the outer frame body.

Abstract: The present invention provides a mold injection method for semiconductor device by which the problem of residual metal is overcome. The inventive method comprises following steps: die attaching; wire bonding; attaching solder-resisting tape around the die; molding; removing the older-resisting tape; marking; ball placement: and singulation.

Abstract: A reusable metal frame for manufacturing of encapsulated semiconductor devices includes a metal sheet having a plurality of openings disposed in compliance with topology of semiconductor devices carried by a supporting structure. During the molding operation, the frame is superposed over the supporting structure with each semiconductor device to be encapsulated, positioned centrally within one of the openings. The encapsulating material (resin, plastic, or the like) is supplied to each semiconductor device and stays within each opening, held in place by continuous uninterrupted contour of each opening. After the encapsulating material has been cooled, the metal frame is readily removed, and may be used in other molding operations.
