Abstract:
A semiconductor chip package and a method for manufacturing thereof includes sequentially forming upper dielectric layer patterns and lower dielectric patterns over a substrate to expose an underlying metal line such that the lower dielectric layer patterns overlap the metal line, positioning a solder ball over and contacting the lower dielectric layer patterns such that the solder ball does not contact the metal line, and then placing the solder ball in a contacting position over the metal line by performing an etching process on the lower dielectric layer patterns. Therefore, no cracks occur on the chip pads so that there is no concern of short phenomenon generated in the terminal.
