Ultrasonic bonding method, ultrasonic bonding apparatus, and ultrasonic bonding system

Abstract

According to one embodiment, an ultrasonic bonding method for bonding a plurality of bonding members together by applying pressure and an ultrasonic wave includes a pressing step of applying pressure to one bonding member and another bonding member so as to press against each other, an application step of applying an ultrasonic wave to the one bonding member, a detection step of detecting a vibration state of another bonding member during the application step, and a step of determining a state of bonding between the bonding members based on the vibration state acquired in the detection step.
