  • Publication number: 20080191364
    Abstract: The present invention relates to an apparatus for stacking semiconductor chips, a method for manufacturing a semiconductor package using the same and a semiconductor package manufactured thereby. The apparatus for stacking semiconductor chips may comprise two tables for supporting wafers, a picker for picking up semiconductor chips and a picker transfer unit for moving the picker vertically and horizontally. The method for manufacturing a semiconductor package using the same may allow easy and rapid stacking of semiconductor chips, thereby improving the productivity of semiconductor package manufacture. Further, a semiconductor chip having a relatively thick film is attached onto another semiconductor chip having a relatively thin film. The thicker semiconductor chip may protect the thinner semiconductor chip from faults such as chipping or warpage which may occur due to external shocks such as that caused by a picker, thereby improving the reliability of the package.
