  • Patent number: 8070199
    Abstract: Disclosed is a semiconductor package pickup apparatus. The apparatus includes a picker base formed with first and second main feeding holes, which are connected to each pneumatic line providing a pneumatic pressure and aligned in a dual-layer structure, and an adsorption pad coupled to a lower portion of the picker base and formed with adsorption holes connected to the first and second main feeding holes. The pneumatic pressure supplied into the first and second main feeding holes is independently controlled, so that the apparatus easily loads or picks up semiconductor packages, even if the size of the semiconductor packages becomes reduced.
    Type: Grant

  • Patent number: 8013273
    Abstract: Disclosed are an apparatus and a method for manufacturing an absorption pad used for picking up a package or a strip during a semiconductor manufacturing process. The apparatus includes a workpiece transfer device on which a workpiece is mounted, a laser generator installed above the workpiece transfer device while being spaced apart from the workpiece transfer device by a predetermined distance, a driving unit for moving the workpiece transfer device and the laser generator relative to each other, and a controller for controlling the laser generator. It is possible to precisely form patterns having various sizes and shapes according to use of the absorption pad and the size of the package. Processing conditions for the workpiece are standardized, so that the processing time and manufacturing cost for the absorption pad are minimized.
