Patent ID: 6838316

Claim:
A semiconductor device manufacturing method comprising: forming a bump on at least one of a semiconductor chip and a printed circuit board; applying a sealing material to a surface of one of the semiconductor chip and the printed circuit board; fixing a surface of the semiconductor chip opposite to an element formation surface to a porous stage by porous chucking; chucking a surface of the printed circuit board opposite to a wiring electrode formation surface by a tool; moving down the tool toward the porous stage, facing down the printed circuit board on the semiconductor chip, and thereby opposing the semiconductor chip to the printed circuit board via the bump; and flip-chip-connecting the printed circuit board to the semiconductor chip via the sealing material while applying ultrasonic waves to the printed circuit board to promote bonding by the bump, wherein the flip-chip-connecting includes electrically connecting the semiconductor chip and the printed circuit board via the bump, and sealing the semiconductor chip and the printed circuit board by the sealing material.
