  • Patent number: 7459774
    Abstract: In a stacked chip configuration, and manufacturing methods thereof, the gap between a lower and an upper chip is filled completely using a relatively simple process that eliminates voids between the lower and upper chips and the cracking and delamination problems associated with such voids. The present invention is applicable to both chip-level bonding and wafer-level bonding approaches. A photosensitive polymer layer is applied to a first chip, or wafer, prior to stacking the chips or stacking the wafers. The photosensitive polymer layer is partially cured, so that the photosensitive polymer layer is made to be structurally stable, while retaining its adhesive properties. The second chip, or wafer, is stacked, aligned, and bonded to the first chip, or wafer, and the photosensitive polymer layer is then cured to fully bond the first and second chips, or wafers. In this manner, adhesion between chips/wafers is greatly improved, while providing complete gap fill.

  • Publication number: 20080179734
    Abstract: A stacked package includes a printed circuit board (PCB), a plurality of semiconductor chips, plugs and a controller. The semiconductor chips are sequentially stacked on the PCB. The plugs electrically connect each of the semiconductor chips to the PCB. The controller is disposed in any one of the semiconductor chips. The controller is electrically coupled to the plugs. Thus, the controller may be built in the semiconductor chip by a separate process so that a mechanical impact generated in a process for bonding the controller is not applied to the semiconductor chips. Further, a mechanical impact applied to the controller, which is generated in a process for forming a protection member, may be reduced.

  • Publication number: 20080179727
    Abstract: Provided are semiconductor packages having immunity against a void due to an adhesive material and methods of fabricating the same. The semiconductor packages and the methods of fabricating the same can eliminate voids between package bodies to minimize delamination of the package bodies from the semiconductor package during the life time of semiconductor devices. To this end, a circuit substrate, a controller, and package bodies may be prepared. Each of the package bodies may have a package substrate, an adhesive pattern, and a package insulating layer. The package insulating layer may be formed on the package substrate to surround the adhesive pattern. The package bodies may be formed between the controller and the circuit substrate and contact the controller and the circuit substrate.

  • Publication number: 20080169545
    Abstract: A stacked structure of semiconductor devices may include a plurality of stacked semiconductor devices, each having an upper surface and a lower surface and one or more via electrodes protruding from the upper surface to the lower surface. The via-electrodes may have upper parts (heads) protruding from the upper surface and lower parts (ends) protruding from the lower surface. The stacked semiconductor devices may be electrically connected to each other through the via-electrodes. A first adhesive film (e.g., patternable material) and a second adhesive film (e.g. puncturable material) may be formed between the stacked semiconductor devices. The stacked structure of semiconductor devices may be mounted on the upper surface of a printed circuit board (PCB) having a mount-specific adhesive film to form a semiconductor device package. The mounted stacked structure and the upper surface of the PCB may be further covered with a molding material.

  • Patent number: 7371614
    Abstract: An image sensor device and methods thereof. In an example method, a protective layer may be formed over at least one microlens. An adhesive layer may be formed over the protective layer. The adhesive layer may be removed so as to expose the protective layer. The protective layer may be removed so as to expose the at least one microlens, the exposed at least one microlens not including residue from the adhesive layer. The at least one microlens may have an improved functionality due at least in part to the lack of residue from the adhesive layer. In an example, the at least one microlens may be included in an image sensor module.
