Abstract:
1. A bonding apparatus for flip-chip-bonding bumps of semiconductor devices, which have been adhered on a substrate by a non-conductive adhesive, to terminal sections of the substrate in a state where the semiconductor devices are clamped between an upper die and a lower die, the bonding apparatus comprising: the upper die having a built-in heat source and a clamping face, the upper die being capable of heating and pressing the semiconductor devices onto the clamping face in a state where the substrate is supported by the lower die; and the lower die having a substrate holding plate and a clamping face, the substrate on which the semiconductor devices have been adhered being mounted on the substrate holding plate, the substrate holding plate being floating-supported, by a plurality of supporting rods, in a state where the substrate holding plate is separated from the clamping face of the lower die so as to increase thermal resistance, wherein the substrate, which is mounted on the substrate holding plate and floating-supported, is moved toward the clamping face of the upper die, by a closing action of the upper die and the lower die, so as to preheat the substrate and the semiconductor devices by radiation heat, the semiconductor devices, which are mounted on the substrate held by the substrate holding plate, are pressed onto the clamping face of the upper die by progression of the closing action, a plurality of the supporting rods are retracted into the lower die and the substrate holding plate is moved until tightly contacting the clamping face of the lower die by completing of the closing action, and the semiconductor devices, which are mounted on the substrate held by the substrate holding plate and which are clamped between the upper die and the lower die, are heated and pressed so as to cure the non-conductive adhesive and bond the bumps of the semiconductor devices to the terminal sections of the substrate.
