A flip-chip (FC) package structure is provided. The FC package structure includes a substrate, a chip, a plurality of copper platforms, a plurality of copper bumps, a plating layer, a circuit layer and a solder mask layer. The copper bumps are disposed on the substrate. The copper platforms are stacked on the copper bumps. The plating layer covers the copper bumps and the copper platforms, for contacting with chip foot pads configured at a bottom of the chip. The FC package structure does not need to reserve a space for wire bonding, thus saving the area of the substrate. The copper platforms are stacked on the copper bumps, and are higher than the circuit pattern layer. Therefore, the chip is blocked up, and the gap between the chip and the substrate is enlarged, thus preventing the risk of configuring voids when filling the cladding material and improving the packaging yield. |
