Abstract:
1. A bonding method of semiconductor substrates to perform three-dimensional mounting by coupling a first semiconductor substrate in which pads are formed, to a second semiconductor substrate in which bumps are formed, through an interlayer adhesive, the method comprising the steps of: first causing a surface of the first semiconductor substrate on which the pads are formed, and a surface of the second semiconductor substrate on which the bumps are formed, to come into contact with each other through the interlayer adhesive; second adjusting the positions of the first and second semiconductor substrates coming into contact with each other through the interlayer adhesive; third applying an adhesive to the periphery of the first and second semiconductor substrates whose positions have been adjusted in the second step, and hardening the adhesive applied to the periphery thereof; and fourth electrically coupling the pads and the bumps while hardening the interlayer adhesive, by heating and pressing the first and second semiconductor substrates having been subjected to the step
