  • Patent number: 7880311
    Abstract: A stacked semiconductor package includes a semiconductor chip module including at least two semiconductor chips, each semiconductor chip having a first face, a second face opposite to the first face, and a circuit part. A thorough portion passes through the first and second faces of the semiconductor chip. A recess part is formed in a portion of the second face where the second face and the through portion meets. A through electrode is electrically connected to the circuit part and is disposed inside of the through portion. A connection member is disposed in the recess part to electrically connect the through electrodes of adjacent stacked semiconductor chips. And the semiconductor chip module is mounted to a substrate. The stacked semiconductor package prevents both gaps between semiconductor chips and misalignment of the through electrode.
