  • Patent number: 8698156
    Abstract: It is an object of the invention to improve the production efficiency in sealing a thin film integrated circuit and to prevent the damage and break. Further, it is another object of the invention to prevent a thin film integrated circuit from being damaged in shipment and to make it easier to handle the thin film integrated circuit. The invention provides a laminating system in which rollers are used for supplying a substrate for sealing, receiving IC chips, separating, and sealing. The separation, sealing, and reception of a plurality of thin film integrated circuits can be carried out continuously by rotating the rollers; thus, the production efficiency can be extremely improved. Further, the thin film integrated circuits can be easily sealed since a pair of rollers opposite to each other is used.

  • Patent number: 7608486
    Abstract: The invention relates to a device for encapsulating with encapsulating material an electronic component, in particular a semiconductor, fixed on a carrier, comprising: two co-acting mould parts which are displaceable relative to each other between an encapsulating position, in which the mould parts, when closing onto the carrier, occupy a position for defining at least one mould cavity, and an opened position in which the mould parts are situated at a greater distance from each other than in the encapsulating position, and feed means for encapsulating material connecting onto the mould cavity. The invention also relates to a method for encapsulating with encapsulating material an electronic component fixed on a carrier.

  • Patent number: 7605462
    Abstract: A universal substrate includes a plurality of inner pads and a plurality of outer pads. A plurality of bifurcate wirings and a plurality of fuses are formed on a surface of the substrate. The fuses are connected with the bifurcate wirings in series. By the bifurcate wirings and the fuses, each of the inner pads is electrically connected to all of the outer pads to provide optional electrical disconnections therebetween. Accordingly, the universal substrate can provide for various chips with different serial arrangements of bonding pads without replacing or manufacturing another kind of substrate.

  • Patent number: 7602055
    Abstract: A semiconductor device with a WLP structure that enables the improvement of heat resistance. A dam layer which spreads over a PI film and an Si substrate for a chip is formed between the Si substrate and a sealing resin so as to surround the chip on all sides. A material for the dam layer is selected so that good adhesion will be obtained between the dam layer and the Si substrate, between the dam layer and the PI film, and between the dam layer and the sealing resin. As a result, even if a crack appears at a portion on a side of the semiconductor device where the Si substrate and the sealed resin are joined in a heating environment, the crack does not run inside the dam layer. This prevents the peeling of the sealing resin or peeling inside the chip and the performance of the semiconductor device is maintained.

  • Publication number: 20090230567
    Abstract: A method of grinding a molded semiconductor package to a desired ultra thin thickness without damage to the package is disclosed. Prior to grinding a molded package to a desired package thickness, the package may be protected from excessive mechanical stress generated during grinding by applying a protective tape to enclose interconnects formed on the package. This way, the protective tape provides support to the semiconductor package during package grinding involving the mold material as well as the die. In the post-grind package, the grinded die surface may be exposed and substantially flush with the mold material. The protective tape may then be removed to prepare the post-grind package for connection with an external device or PCB.

  • Patent number: 7579684
    Abstract: Methods for packaging microfeature devices on and/or in microfeature workpieces at the wafer level and microfeature devices that are formed using such methods are disclosed herein. In one embodiment, a method comprises providing a workpiece including a substrate having a plurality of microelectronic dies on and/or in the substrate. The individual dies include integrated circuitry and pads electrically coupled to the integrated circuitry. The method then includes depositing an underfill layer onto a front side of the substrate. The method also includes selectively forming apertures in the underfill layer to expose the pads at the front side of the substrate. The method further includes depositing a conductive material into the apertures and in electrical contact with the corresponding pads. In one aspect of this embodiment, the underfill layer is a photoimageable material.

  • Patent number: 7557438
    Abstract: A stacked die package includes a substrate (210, 310), a first die (220, 320) above the substrate, a spacer (230, 330) above the first die, a second die (240, 340) above the spacer, and a mold compound (250, 370) disposed around at least a portion of the first die, the spacer, and the second die. The spacer includes a heat transfer conduit (231, 331, 333, 351, 353) representing a path of lower overall thermal resistance than that offered by the mold compound itself. The heat transfer path created by the heat transfer conduit may result in better thermal performance, higher power dissipation rates, and/or lower operating temperatures for the stacked die package.
