A stacked semiconductor package includes: a first semiconductor chip formed with a first through electrode, the first through electrode protruding above a first surface of the first semiconductor chip; a first polymer layer formed over the first surface of the first semiconductor chip such that the first through electrode is exposed by the first polymer layer; a second semiconductor chip having a first surface attached onto the first semiconductor chip by medium of the first polymer layer and a vial hole passing through the second semiconductor chip, the first surface of the second semiconductor chip being formed with a bonding pad having a through hole which corresponds to the first through electrode; and a second through electrode located within the through hole and the via hole and is electrically connected with the first through electrode.
