    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 stacked structure for memory chips includes a substrate, a lower memory chip, an upper memory chip, and an insulation medium. The substrate has an upper surface, a lower surface and a slot penetrating through the substrate from the upper surface to the lower surface. The lower memory chip has a central portion formed with a plurality of bonding pads. The lower memory chip is arranged on the upper surface of the substrate. The plurality of bonding pads is exposed via the slot of the substrate, and the bonding pads are electrically connected to the lower surface of the substrate via a plurality of wires. The upper memory chip has a central portion formed with a plurality of bonding pads. The upper memory chip is arranged on the lower memory chip in a back-to-back manner with respect to the lower memory chip so that the plurality of bonding pads of the upper memory chip faces upwards. The insulation medium has a central portion formed with a slot. The plurality of bonding pads of the upper memory chip is exposed via the slot of the insulation medium. The insulation medium is formed with a plurality of traces electrically connecting to the bonding pads of the upper memory chip and the upper surface of the substrate via a plurality of wires. Accordingly, the length and radian of each wire can be reduced so that a better signal transmission effect and a smaller package volume can be obtained.
