Abstract:
A hybrid wiring board, comprising:a first wiring substrate having a first face and a second face, the first wiring substrate having first wiring layers formed onto the first and second faces of the first wiring substrate, the first wiring layers being connected electrically with each other through the first wiring substrate;a second wiring substrate having a first face and a second face, the second wiring substrate having second wiring layers formed onto the first and second faces of the second wiring substrate, the second wiring layers being connected electrically with each other through the second wiring substrate;an insulating resin layer interposed between and contacting the first face of the first wiring substrate and the second face of the second wiring substrate, wherein the first wiring layer on the first face of the first wiring substrate and the second wiring layer on the second face of the second wiring substrate are intruded into the insulating resin layer; anda conductive filled pillar pierced through the insulating resin layer so as to connect the first wiring layer on the first face of the first wiring substrate and the second wiring layer on the second face of the second wiring substrate.
