Abstract
A chip attraction passageis provided extending through a housingA, a tool base, and a bonding tool. When the chip attraction passageis attracted by the vacuum source, a semiconductor chipcan be attracted to and held on the lower surface of the bonding tool. The tool baseis configured by laminating transmitting membersand. A connection passage, which is a main part of the chip attraction passage, is configured by a grooveB formed on the upper surface of the transmitting memberand a through-holeA in the center of the transmitting member. When the semiconductor chipis heated by laser beams L and bonded to a substrate, even if flux or the like adhering to bumpstranspires and adheres in the connection passage
