发明名称 Stacked-chip packaging structure and fabrication method thereof
摘要 A stacked-chip packaging structure includes chip sets, a heat sink, a substrate, a circuit board, and solder balls. The chip sets are stacked together, each of which has a heat-dissipation structure and a chip. The heat-dissipation structure has a chip recess, through holes arranged in the chip recess, and an extending portion extending from the chip recess. The chip disposed in the chip recess has bumps. Each bump on the chip is correspondingly disposed in one of the through holes of the heat-dissipation structure. The extending portion of the heat-dissipation structure of each chip set contacts that of the neighboring chip set. The heat sink and the substrate are disposed at two opposite sides of the chip sets, respectively. The circuit board is below the substrate. The solder balls are between the circuit board and the substrate.
