Abstract:
1. A circuit device manufacturing method comprising: forming conductive films that are laminated in multiple layers with interlayer insulating layers interposed in between; forming a first conductive wiring layer by selective removal of the conductive film at a top surface; forming through holes in the interlayer insulating layers and forming connection means in the through holes to electrically connect the first conductive wiring layer with the conductive film at a rear surface; affixing a circuit element to the first conductive wiring layer and electrically connecting the circuit element to the first conductive wiring layer via conductive wires; irradiating plasma onto the first conductive wiring layer, the circuit element and the conductive wires; and forming a resin layer so as to cover the circuit element; and forming a second conductive wiring layer by selective removal of the conductive film at the rear surface after the irradiation.
