Abstract:
A method of manufacturing a semiconductor device, comprising:mounting a semiconductor element on a substrate including first connection electrodes, first interconnections electrically connected to said first connection electrodes and a first alignment mark with said semiconductor element electrically connected to said first interconnections, positioning and stacking said substrate having said semiconductor element mounted thereon on a core substrate based on recognition of said first alignment mark, said core substrate having second connection electrodes and second interconnections electrically connected to the second connection electrodes, and having adhesive layers formed on both surfaces thereof; and performing thermo-compression bonding at temperatures of 120Â° C. or less at which an adhesive agent of said adhesive layers is melted, without being cured, to temporarily fix the substrate having said semiconductor element mounted thereon on said core substrate by tackiness of said adhesive agent.
