摘要: PROBLEM TO BE SOLVED: To make a "rigid connection" of a boundary surface of an electrode connection part of a connection structure, constituted by connecting a 1st electrical structure and a 2nd electrical structure to each other with a conductive adhesive, through a thermosetting treatment, using the conductive adhesive without requiring any dedicated process by fusing metal particulates.
SOLUTION: The connection structure comprises the electrode connection part whose continuity is secured by fusing at least one of a 1st electrode, provided to a 1st electric structure and a 2nd electrode provided to a 2nd electric structure and the metal particulates and an intermediate connection part which ensures the continuity of an intermediate part between the 1st electrode and 2nd electrode with the conductive adhesive, and the metal particulates are metal particulates which begin to be fused below the thermosetting temperature of the conductive adhesive, which contain a conductive filler of such a particle size that the filler will not be fused below the thermosetting temperature of the conductive adhesive.

摘要: PROBLEM TO BE SOLVED: To improve reliability of bonding by a bonding device that bonds electrodes on a semiconductor die and a substrate by using a metal nano-paste. SOLUTION: A semiconductor die 12 having electrodes 12a on which bumps are formed by injecting fine droplets of a metal nano-paste is placed face down on a circuit board 19 having electrodes 19a on which bumps are formed, and the electrodes 12a on the semiconductor die 12 and the electrodes 19a on the circuit board 19 are overlapped on each other with bonding bumps 250 interposed therebetween. After that, the gap between each of the overlapped electrodes 12a, 19a is compressed to a predetermined gap H3 smaller than the gap obtained when the electrodes 12a, 19a are overlapped, thereby applying pressure on the bumps between the respective electrodes 12a, 19a. In addition, the bumps between the respective electrodes 12a, 19a are heated and metal nano-particles of the bumps are pressed and sintered to form joint metals 300, so that the electrodes 12a, 19a are electrically connected to each other.
