  • Patent number: 7534702
    Abstract: An efficient mass-production method of very small devices that can receive or transmit data in touch, preferably, out of touch is provided by forming an integrated circuit made of a thin film over a large glass substrate and transferring the integrated circuit to another backing to be divided. Especially, the integrated circuit made of a thin film is difficult to use since there is a threat that the integrated circuit is scattered in the handling of the integrated circuit since the integrated circuit is extremely thin. According to the present invention, multiple openings reaching a peel layer are provided, a material body having a pattern shape that does not cover regions (the openings and a device portion) is provided, and then, a gas or liquid containing fluorine halide is introduced to partially remove the peel layer.

For each die, the n and p layers are electrically bonded to a package substrate that extends beyond the boundaries of the LED die such that the LED layers are between the package substrate and the growth substrate. The package substrate provides electrical contacts and conductors leading to solderable package connections. The growth substrate is then removed.

    Abstract: A semiconductor stack package includes lower and upper individual packages. When the upper individual package is stacked on the lower individual package, a heat-conducting layer provided under the upper package touches a heat-mediating layer provided on the lower package. Thus, a layer of trapped air found in conventional stack packages is eliminated, and a direct heat-dissipating path is produced through both the heat-conducting layer and the heat-mediating layer. Therefore, the heat dissipation of the stack package is improved. Alternatively, the stack package may have a symmetric configuration in which each IC chip faces away from each other. A memory module has several stack packages mounted on one or both surfaces of a module board. The method includes forming the packages and stacking the packages.

The IC die is electrically connected to one or more of a plurality of electrically conductive traces formed on the first side of the substrate. The substrate includes a hole approximate an outer edge of the IC die. The first side of the substrate is then positioned in contact with at least a portion of the first side of the backplate. The IC die is positioned within the cavity with a second side of the IC die in thermal contact with the backplate.

  • Patent number: 7470978
    Abstract: In one embodiment of the invention, a lead-frame is designed for use in IC packages such as those conforming to the TO 220 standard or other standards for power packages. The device areas of the lead-frame are arranged in columns, and each column is molded so as to expose a portion of the leads. The device areas can then be cingulated by sawing, as in conventional QFN packages. In this manner, packages conforming to power package standards such as the TO 220 standard can be produced much quicker and cheaper than they can in conventional trim and forming methods.

    Abstract: Disclosed are a semiconductor chip package and a method for fabricating the same. The semiconductor chip package includes a semiconductor chip and a circuit board. The semiconductor chip is bonded to the circuit board by means of adhesive except for a metal-exposed region of the semiconductor chip. Anti-migration material is formed between the circuit board and a predetermined portion of the semiconductor chip, in which the predetermined portion of the semiconductor chip has no adhesive, in order to prevent material contained in the metal trace from migrating to the metal-exposed region of the semiconductor chip. A lamination phenomenon is not created between the circuit board and the semiconductor chip after the HAST has been carried out.

    Abstract: The invention provides a taped lead frame for use in manufacturing electronic packages. The taped lead frame is composed of a tape and a lead frame formed from a plurality of individual metal features attached to the tape and arranged in a footprint pattern. The method of making the invention enables the thickness of conventional frames to shrink significantly to result in thinner packages for improved heat dissipation and shorter geometries for improved electrical performance. A plurality of such lead frames are arranged in an array on a sheet of tape and each lead frame is separated from surrounding lead frames by street regions on the tape such that no metal feature extends into a street region. Integrated circuit chips are attached and electrically connected to the lead frames and an encapsulant is applied, cured and dried over the lead frames and the street regions.
