Patent ID: 7795139

Claim:
A method for manufacturing a semiconductor chip for packaging, comprising the steps of: forming a groove having a side wall on the upper surface of a semiconductor chip having a bonding pad on the upper surface thereof, wherein the bonding pad is formed adjacent to the groove so as to be spaced apart laterally from the groove, wherein the groove is closer to the outer perimeter of the semiconductor chip upper surface than the bonding pad; forming an insulation layer on the side wall of the groove; depositing a seed metal layer over the semiconductor chip including the groove formed with the insulation layer in the side wall; plating a metal layer over the seed metal layer so as to fill the groove with the metal layer and to cover at least a portion of the upper surface of the semiconductor chip including the bonding pad; removing a partial thickness of the metal layer over the groove and the upper surface of the semiconductor chip by etching back to reduce the overall thickness of the metal layer such that the metal layer remains covering at least a portion of the upper surface of the semiconductor chip including the bonding pad; simultaneously forming a through silicon via filled with metal in the groove and a distribution layer extending laterally on the upper surface of the semiconductor chip so as to connect the through silicon via to the bonding pad by patterning the etched back metal layer, removing a portion of the lower surface of the semiconductor chip to reduce the thickness thereof such that a part of the through silicon via at the bottom of the groove protrudes out of the lower surface of the semiconductor chip; and forming mold parts on the upper and lower surfaces of the semiconductor chip excluding the through silicon via so as to expose an entire upper surface of the distribution layer extending laterally so as to connect the through silicon via to the bonding pad and the bottom portion of the through silicon via such that the semiconductor chip is protected from mechanical shocks by the mold parts.
