摘要:
A semiconductor package structure having central leads according to the invention includes a substrate, a semiconductor device, a plurality of wires, and glue. A long slot penetrating through the substrate is formed in the substrate. A plurality of bonding pads formed on the semiconductor device are mounted on substrate. The plurality of bonding pads on the semiconductor device are exposed via the long slot of the substrate. The length of the semiconductor device is smaller than that of the long slot of the substrate so that a channel is formed at one side of the long slot when the semiconductor device is mounted on the substrate. The plurality of wires are arranged within the long slot of the substrate for electrically connecting the plurality of bonding pads on the semiconductor device to the plurality of signal output terminals on the substrate. The glue is provided for sealing the upper surface of the substrate to protect the semiconductor device. The glue is poured into the long slot of the substrate via the channel formed by the long slot of the substrate, for covering the plurality of wires.
摘要:
A substrate structure for an integrated circuit package. The substrate is electrically connected to a circuit board and an integrated circuit. The substrate includes a plurality of metal sheets and glue. The metal sheets are arranged opposite to each other. Each of the metal sheets includes a first surface and a second surface. The glue is used for sealing the plurality of metal sheet to form the substrate. The first surfaces and second surfaces of the metal sheets are exposed to the outside of the glue so as to form a plurality of signal input terminals for electrically connecting to the integrated circuit and a plurality of signal output terminals for electrically connecting to the circuit board. Thus, the signal output terminals of the metal sheets can be electrically connected to the circuit board smoothly. Furthermore, the signal transmission distance between the integrated circuit and the circuit board can be shortened so that better signal transmission effect can be obtained. A method for manufacturing the substrate is also disclosed.

A package structure for a photosensitive chip includes a substrate having an upper surface and a lower surface, and a frame layer having a first surface and a second surface. The frame layer is formed on the substrate by way of injection molding with the first surface contacting the upper surface. A cavity is formed between the substrate and the frame layer. The second surface is formed with a depression in which plural projections each having a suitable height are formed. The frame layer is formed directly on the substrate by way of injection molding. The package structure further includes a photosensitive chip arranged within the cavity, a plurality of wires for connecting the substrate to the photosensitive chip, and a transparent layer rested on the projections within the depression. Accordingly, the yield can be improved and the manufacturing processes can be facilitated.
