ABSTRACT:
A method of connecting first electrodes formed on a first substrate to second electrodes formed on a second substrate and partially coated with a resist pattern so as to substantially expose an opening thereof at a surface of the second electrodes includes (a) coating the second electrodes with a solder at the opening of the resist pattern, (b) aligning the first electrodes with the second electrodes, and (c) electrically connecting the first electrodes to the second electrodes through the solder by heat-pressing the first and second electrodes with a heat-pressure bonding head including a tip face having a width smaller than a width of the opening of the resist pattern so as to heat-press the first and second electrodes at an entire region of the tip face of the heat-pressure bonding head. The method is effective in performing a good electrical connection between electrodes through a solder irrespective of an amount of the solder.
