Abstract:
A method for fabricating a circuit device, comprising:preparing an insulation resin sheet having a surface of a conductive layer coated with insulation resin; forming holes in said insulation resin at appointed points on said insulation resin sheet, and selectively exposing the rear side of said conductive layer; forming a conductive plated layer in said holes and on the surface of said insulation resin; forming a first conductive path layer by etching said conductive plated layer to an appointed pattern; fixing semiconductor elements on said first conductive path layer; providing a sealing resin layer over said first conductive path layer and said semiconductor elements; forming a conductive path layer by etching said second conductive layer to an appointed pattern; and forming external electrodes at appointed points of said second conductive path layer.
