发明名称 STACKED WAFER MANUFACTURING METHOD
摘要 A manufacturing method for a stacked wafer composed of a mother wafer and a stacking wafer bonded together. The mother wafer has a plurality of first semiconductor devices and the stacking wafer has a plurality of second semiconductor devices respectively corresponding to the first semiconductor devices. The manufacturing method includes the steps of bonding the front side of a substrate through a bonding layer to the front side of the stacking wafer, next grinding the back side of the stacking wafer to reduce the thickness of the stacking wafer to a predetermined thickness, next stacking the unit of the stacking wafer and the substrate bonded together on the mother wafer in the condition where the back side of the stacking wafer is opposed to the front side of the mother wafer, thereby bonding electrodes exposed to the back side of each second semiconductor device to electrodes of each first semiconductor device formed on the front side of the mother wafer, and finally grinding the substrate bonded to the front side of the stacking wafer to thereby remove the substrate.
