| 摘要 |
The package substrate of the present invention comprises a carrying board, bump pads, wire bonding pads, a solder mask, metallic bumps, and a metallic protective layer. The solder pads and the wire bonding pads are disposed on the surface of the carrying board. The solder mask is patterned to expose bump pads, wire bonding pads, and part of the surface of the substrate on the periphery of the wire bonding pads. The metallic bumps are disposed on the surface of the bump pads and extend to the surface of the solder mask. The metallic protective layer is disposed on the surfaces of the metallic bumps and the wire bonding pads. Besides, a method for manufacturing this package substrate, a semiconductor package structure comprising this package substrate, and a manufacturing method thereof are disclosed. Therefore, the manufacturing process of the package substrate is simple, and the package substrate is slim.
