Description of the Invention: [Technical Field of the Invention] The present invention relates to a package substrate and a method of fabricating the same, and more particularly to a package substrate for preventing short-circuiting of electrical interconnections of the same layer and a method of fabricating the same. [Prior Art] In the current package substrate process, a plurality of dielectric layers are stacked on the substrate body, and a desired patterned circuit is disposed between the dielectric layers to form a package substrate structure; For the laminated structure, the bonding force between the layers is very important. In order to ensure the electrical connection of the layers, the conventional technique forms a rough sugar surface on the surface of the dielectric layer to increase the bonding strength between the dielectric layer and the line. Moreover, since the wiring trend of the package substrate is toward high-density and fine-line pitch, the method of fabricating the package substrate line is mainly the electric ore patterned circuit.
