Abstract:
1. A method of manufacturing an integrated circuit device, said method comprising: preparing an integrated circuit element which has an element substrate, a predetermined conductive pattern and a projecting electrode formed on said element substrate; preparing a packaging substrate which has an external connecting terminal having a predetermined height and is electrically connected with a mounting substrate, and a supporting layer which has a thickness not smaller than said predetermined height of said external connecting terminal; said supporting layer being formed at least in an area corresponding to a position where said integrated circuit element is mounted; bringing said supporting layer into contact with a stage upon setting said packaging substrate on said stage with an element mounting surface being directed to the outside; and joining said integrated circuit element to said element mounting surface of said packaging substrate by applying ultrasonic wave vibration while pushing said integrated circuit element towards said supporting layer.
