Abstract:
1. An interconnection structure for a package, comprising: a substrate body having a conductive portion formed on a surface thereof; a first photosensitive dielectric layer formed on the surface of the substrate body and having a plurality of first openings exposing a part of the conductive portion; a first conductive trace layer formed in the first openings; a second photosensitive dielectric layer formed on the first photosensitive dielectric layer and the first conductive trace layer and having a plurality of vias for exposing a portion of the first conductive trace layer; a plurality of first conductive vias each formed in a corresponding one of the vias and electrically connected to the first conductive trace layer; a third photosensitive dielectric layer formed on the second photosensitive dielectric layer and having a plurality of second openings for exposing the first conductive vias and a portion of the second photosensitive dielectric layer; and a second conductive trace layer formed in the second openings and electrically connected to the first conductive trace layer through the first conductive vias.
