Abstract: A semiconductor package includes a substrate, first bumps, a first chip, metal pillars, second bumps and a second chip. The substrate includes first and second conductive pads which are located on a top surface of the substrate. Both ends of the first bumps are connected to the first conductive pads and the first chip, respectively. Both ends of the metal pillars are connected to the second conductive pads and one end of the second bumps, respectively. A cross-sectional area of each of the metal pillars is larger than that of each of the second bumps. The second chip is connected to the other end of the second bumps and located above the first chip.

Abstract: A flip-chip bonding structure includes a substrate and a chip. A lead of the substrate includes a body, a hollow opening, a bonding island and at least one connecting bridge. The hollow opening is in the body and surrounded by the body. The bonding island is located in the hollow opening such that there is a hollow space in the hollow opening and located between the body and the bonding island. The connecting bridge is located in the hollow space to connect the body and the bonding island. A bump of the chip is bonded to the bonding island by a solder. The solder is restricted on the bonding island and separated from the body by the hollow space so as to avoid the solder from overflowing to the body and avoid the chip from shifting.
