ABSTRACT:
A die bonding apparatus for die bonding at least two members, which are heated in a heat treatment furnace, comprising a first member having a surface to be die bonded on which solder is disposed and a second member disposed to face the first member in a state in which the solder disposed on the surface of the first member to be die bonded is interposed therebetween, and a base portion for mounting the first member thereon in a predetermined position, wherein the base portion has a temperature distribution so that a temperature of a vicinity of a central portion in a predetermined direction of the base portion is higher than that of a vicinity of an end portion of the base portion in a state in which heating is effected in the heat treatment furnace to, so that it is possible to suppress the occurrence of bubbles in the solder.
