Abstract
Through holesare formed to penetrate a core substrateand lower interlayer resin insulating layers, and via holesare formed right on the through holes, respectively. Due to this, the through holesand the via holesare arranged linearly, thereby making it possible to shorten wiring length and to accelerate signal transmission speed. Also, since the through holesand the via holesto be connected to solder bumps(conductive connection pins), respectively, are directly connected to one another, excellent reliability in connection is ensured.
