Patent ID: 8501583

Claim:
A method for connecting between substrates in which a first substrate having a plurality of first electrodes is located so as to face a second substrate having a plurality of second electrodes, the method comprising: supplying a resin containing conductive particles and a gas bubble generating agent to a space between the first substrate and the second substrate; heating the resin to melt the conductive particles contained in the resin and generate gas bubbles from the gas bubble generating agent contained in the resin; and curing the resin, wherein a first step portion is formed on the first substrate in a region other than a region where the first electrodes are formed, and a second step portion is formed on the second substrate in a region other than a region where the second electrodes are formed, in the step of heating resin, the resin is pushed aside by the growing gas bubbles, so that the melted conductive particles contained in the resin are led to a space between the first electrodes and the second electrodes and that a connector made of the melted conductive particles is formed in each space between the first electrodes and the second electrodes so that each first electrode is electrically connected to a corresponding second electrode, and the resin is led to a space located in-between the first step portion and the second step portion, and in the step of curing resin, the first substrate and the second substrate are fixed to each other by the cured resin.
