  • Publication number: 20020151102
    Abstract: A method for manufacturing films used in semiconductor package, comprising the steps of: providing a frame having an upper surface and a lower surface opposite to the upper surface, a through-hole being formed in the frame; mounting a first covering layer onto the lower surface of the frame in order to covering the through-hole; placing a film into the through-hole of the frame, the film being adhered onto the first covering layer; providing a second covering layer for covering the frame and packing the film, the film being located between the first covering layer and the second covering layer; and cutting the film into a plurality of films each having a predetermined size by a cutting tool. The films after being cut may be placed between the lower semiconductor chip and the upper semiconductor chip, so that the plurality of wirings and the lower semiconductor chip are free from being short-circuited, and the bad signal transmission can be avoided.

  • Publication number: 20020096766
    Abstract: A package structure for an integrated circuit includes a substrate, an integrated circuit, an adhesive layer, a plurality of wirings, and a glue layer. The substrate has a first surface and a second surface. The first surface is formed with a plurality of signal input terminals. The second surface is formed with a plurality of signal output terminals for electrically connecting to the circuit board. The integrated circuit has a lower surface and an upper surface. Recesses are formed at two sides of the lower surface, and a plurality of bonding pads are formed on the upper surface. The adhesive layer is used for adhering the lower surface of the integrated circuit to the first surface of the substrate. The wirings are electrically connecting to the bonding pads of the integrated circuit and to the signal input terminals of the substrate. The glue layer is used for sealing the plurality of wirings and the integrated circuits.

  • Publication number: 20020096729
    Abstract: A stacked package structure of an image sensor for electrically connecting to a printed circuit board includes a substrate, an integrated circuit, an image sensing chip, and a transparent layer. The substrate has a first surface and a second surface opposite to the first surface. The first surface is formed with signal input terminals. The second surface is formed with signal output terminals for electrically connecting the substrate to the printed circuit board. The integrated circuit is mounted on the first surface of the substrate and electrically connected to the signal input terminals of the substrate. The image sensing chip is located above the integrated circuit to form a stacked structure with the integrated circuit for electrically connecting to the signal input terminals of the substrate. The transparent layer covers the image sensing chip.

  • Publication number: 20020096754
    Abstract: A stacked structure of integrated circuits for electrically connecting to a circuit board includes a substrate, a lower integrated circuit, a plurality of wirings, and an upper integrated circuit. The lower integrated circuit has a lower surface and an upper surface. The lower surface is adhered onto the first surface of the substrate. A plurality of bonding pads are formed on the upper surface. The wirings each has a first end and a second end. The first ends of the wirings are electrically connected to the bonding pads of the lower integrated circuit. The second ends of the wirings are electrically connected to the signal input terminals of the substrate. The upper integrated circuit has a lower surface and an upper surface. Two recesses are formed at two sides of the lower surface. The upper integrated circuit is adhered to the upper surface of the lower integrated circuit so as to stack above the lower integrated circuit.
