2. A method for bonding a semiconductor device in which operations for bonding a semiconductor device and a substrate are performed repeatedly, the method comprising:
vibrating the semiconductor device and the substrate relatively by applying an ultrasonic vibration to at least one of the semiconductor device and the substrate, while pressing the semiconductor device toward the substrate side, in a state where a bump is provided between the semiconductor device and the substrate;
measuring a time period from a time when starting to apply the ultrasonic vibration, through a period in which a deformation distance of the bump increases significantly, to a time when a significant deformation of the bump ends; and
controlling an output of an ultrasonic vibration during subsequent bonding, based on the measured time period.
