Abstract:
1. A method for manufacturing a circuit device, comprising: mounting a plurality of electronic components on an insulation layer, the insulation layer stacked on a wiring layer of a wiring substrate, the electronic components each including an element to perform an electrical function and each having a bump electrode on one side and a pad electrode on the other side in such a manner that the bump electrode is buried into the insulation layer, the bump electrodes of the electronic components having substantially same height; pressing the pad electrode of each of the mounted electronic components with a heater tool having a planar pressing face to pattern a surface of the insulation layer after the pressing face, and pressing the electronic components into the insulation layer until the pad electrode reaches the surface of the insulation layer to mechanically bond the electronic components and the wiring layer together at the bump electrodes and then harden the insulation layer; and electrically bonding another component to at least part of the pad electrodes pressed by the heater tool.
