A flip-chip package structure comprises a carrier, a block bump, and a die. The carrier is a lead frame or substrate that comprises a lead pattern side, and an electrode pin is disposed on the lead pattern side. The die comprises an active side, and a bond pad is disposed on the active side. The block bump is bonded to the electrode pin; the bond pad of the die is attached on the carrier through the block bump, so that the die and the carrier joint together to form the flip chip package structure. Besides, the block bump is formed by the wedge bonding, and therefore in bumping size and shapes can easily form larger bump, which will increase the compactness between the die and the carrier.
