Classification: CPC H | IPC H

Claim 9:
10. A method of manufacturing a semiconductor package, the method comprising:
providing a substrate including a plurality of basic structures, each of the plurality of basic structures having a first pad on a lower surface thereof, a second pad on an upper surface thereof, and a base insulation layer on the upper surface thereof, the base insulation layer having an upper surface being substantially coplanar with an upper surface of the second pad;
stacking a plurality of first semiconductor chips on the substrate, the plurality of first semiconductor chips having:
a first connection pad directly bonded to the second pad,
a first through-electrode inside each of the plurality of first semiconductor chips and electrically connected to the first connection pad,
first lower insulation layer directly bonded to the base insulation layer;

after stacking the plurality of first semiconductor chips, grinding the plurality of first semiconductor chips to reduce a thickness thereof, such that the first through-electrode has a tip protruding above the plurality of first semiconductor chips;
forming a first upper insulating layer on the plurality of first semiconductor chips, such that the tip of the first through-electrode is completely covered;
grinding the first upper insulating layer, such that the tip of the first through-electrode is removed and an upper surface of the first insulating layer is coplanar with the upper surface of the first through-electrode;
stacking a plurality of second semiconductor chips on the plurality of first semiconductor chips, respectively;
forming a molding member surrounding the stacked first and second semiconductor chips on the substrate; and
cutting the substrate to obtain a plurality of semiconductor packages, such that each of the plurality of semiconductor packages includes a dummy insulation portion having a side surface that is coplanar with a side surface of the molding member.
