Method of manufacturing stack-type semiconductor device and method of manufacturing stack-type electronic component

A method of manufacturing a stack-type semiconductor device, comprising:

• bonding a first semiconductor element on a substrate;
• connecting an electrode part of the substrate and an electrode pad of the first semiconductor element via a first bonding wire;
• placing the first semiconductor element bonded on the substrate, on a stage having a heating mechanism to heat the first semiconductor element;
• positioning a second semiconductor element held by a suction tool above the heated first semiconductor element, with a thermosetting adhesive layer interposed between the first semiconductor element and the second semiconductor element;
• gradually moving down the second semiconductor element, softening or melting the adhesive layer by radiant heat from the heated first semiconductor element and by heat transferred from the first bonding wire, and bringing the adhesive layer into contact with the first semiconductor element while taking the first bonding wire into the adhesive layer;
• and
• applying a pressure to the second semiconductor element while continuing the heating by the heating mechanism, and thermally curing the adhesive layer to bond the first semiconductor element and the second semiconductor element.
