Claim Text:
1. A substrate bonding method comprising: obtaining a first die having an adhesive resin layer with one or more pillar-shaped solder bumps in the adhesive resin layer, a pillar-shaped solder bump is formed on top of an electrode pad that is further in a first substrate; aligning the pillar-shaped solder bump with a second substrate terminal that is in a second substrate; forming a second opening in a position other than a position at which an opening is formed in the adhesive resin layer above the electrode pad further in the first substrate; forming a heat-dissipating structure for thermally connecting the first die and the second substrate by filling the second opening with molten solder; and applying heat and pressure to the first die and the second substrate.
