Abstract:
1. A method for mutually connecting substrates, in which facing a first substrate having a plurality of first electrodes thereon, a second substrate having a plurality of second electrodes thereon is placed, and the first electrodes and the second electrodes are electrically connected to each other via connectors therebetween, the method comprising the steps of: (a) supplying a resin containing conductive particles and a gas bubble generating agent to an area between the first substrate and the second substrate which at least covers the plurality of first electrodes and second electrodes; (b) heating the resin to thereby generate gas bubbles from the gas bubble generating agent contained in the resin; and (c) heating the resin to thereby melt the conductive particles contained in the resin, wherein in the step (a), a partition member sealing a gap between the first substrate and the second substrate is provided near a peripheral portion of the resin, and a peripheral portion of the resin where the partition member is absent is open to an outside, in the step (b), the resin is pushed out toward an outside of the gas bubbles generated from the gas bubble generating agent by growth of the gas bubbles, thereby being guided into spaces between the first electrodes and the second electrodes, and the gas bubbles are discharged to the outside through the peripheral portion of the resin which is open to the outside, and in the step (c), the conductive particles contained in the resin, which have been guided into the spaces between the electrodes, are melted to thereby form the connectors between the electrodes.
