Abstract:
1. A bonding method comprising: (1) preparing a first base material, a second base material, and a transfer base material, the first base material having a first terminal, the second base material having a second terminal, and the transfer base material having a liquid repellency-imparted surface that is repellent against a silicone material- and conductive particle-containing liquid material; (2) applying the silicone material- and conductive particle-containing liquid material to the liquid repellency-imparted surface of the transfer base material to form a liquid coating in patterns of a predetermined shape, and drying the liquid coating to obtain a bonding film patterned into the predetermined shape; (3) imparting energy to the bonding film to provide adhesion near a surface of the bonding film, and thereafter bonding the transfer base material and the first base material to each other via the bonding film, and then separating the transfer base material and the first base material from each other to transfer the bonding film from the transfer base material to the first base material; (4) imparting energy to the bonding film after the transfer to provide adhesion near another surface of the bonding film, and bonding the first base material and the second base material to each other via the bonding film to obtain a temporarily bonded structure of the first base material and the second base material; and (5) applying pressure to the temporarily bonded structure in a thickness direction of the bonding film to finalize the bonding between the first base material and the second base material via the bonding film and electrically connect the first terminal and the second terminal via the conductive particles contained in the bonding film, so as to obtain a bonded structure.
