Abstract
A mounting method for an electronic device element, includes the steps of providing an electronic device element having metal bumps formed on a surface thereof, providing a bonding tool having a pressing surface, providing a mounting substrate, keeping the pressing surface of the bonding tool in contact with a reverse surface of the electronic device element and applying an ultrasonic wave to the bonding tool, thereby mounting the electronic device element on the mounting substrate. The maximum length of the pressing surface of the bonding tool in the ultrasonic-wave-oscillation direction is greater than about 0.5 times the maximum length of the reverse surface of the electronic device element in the ultrasonic-wave-oscillation direction.
