Abstract
A packaging substrate is provided, including a substrate body having a plurality of conductive pads, an insulating protective layer formed on the substrate body for the conductive pads to be exposed therefrom, and a plurality of conductive pillars disposed on the conductive pads. Each of the conductive pillars has a bottom end and a top end narrower than the bottom end, thereby forming a cone-shaped structure that does not have a wing structure. Therefore, the distance between contact points is reduced and the demands for fine-pitch and multi-joints are satisfied.
