Abstract

A semiconductor packaging substrate and a method for fabricating the same are provided. The method includes forming a solder resist structure having a hole on a circuit structure, with a portion of the circuit structure exposed from the hole, and forming a cup-shaped solder stand on the exposed circuit layer and a hole wall of the hole. During a packaging process, the design of the solder stand increases a contact area of a solder tin ball with a metal material. Therefore, a bonding force between the solder tin ball and the solder stand is increased, and the solder tin ball can be protected from being broken or fell off. An electronic package having the semiconductor packaging substrate and a method for fabricating the electronic package are also provided.
