Integrated circuit package system including stacked die
An integrated circuit package system is provided including providing a wafer with bond pads formed on the wafer. A solder bump is deposited on one or more bond pads. The bond pads and the solder bump are embedded within a mold compound formed on the wafer. A groove is formed in the mold compound to expose a portion of the solder bump. The wafer is singulated into individual die structures at the groove.
1. An integrated circuit package system comprising:
providing a wafer with bond pads formed on the wafer;
depositing a solder bump on one or more bond pads;
embedding the bond pads and the solder bump within a mold compound formed on the wafer;
forming a groove in the mold compound to expose a portion of the solder bump; and
singulating the wafer at the groove into individual die structures.
2. The system as claimed in claim 1 wherein forming the groove further comprises:
removing a top portion of the mold compound and a top portion of a solder bump associated with a bond pad.
3. The system as claimed in claim 2 further comprising:
exposing the top portion of two adjacent solder bumps.
4. The system as claimed in claim 1 wherein singulating further comprises:
cutting the wafer and the mold compound between two adjacent bond pads.
5. The system as claimed in claim 1 further comprising:
planarizing the bottom exposed surface of the wafer.
6. The system as claimed in claim 1 further comprising:
providing a printed circuit board; and
connecting the exposed portion of the solder bump to the printed circuit board with electrical connectors,
wherein a combined height of the mold compound and the wafer is at least greater than a height of the electrical connectors.
7. The system as claimed in claim 6 further comprising:
stacking a second semiconductor structure on the mold compound; and
connecting the second semiconductor structure to the printed circuit board.
8. The system as claimed in claim 6 further comprising:
encapsulating the wafer, the mold compound, and the electrical connectors with an encapsulant.
9. The system as claimed in claim 7 further comprises:
providing a layer of film laminate on the mold compound and under the second semiconductor structure.
10. The system as claimed in claim 6 further comprising:
forming solder balls on the bottom surface of the printed circuit board.
