Patent ID: 7670873

Claim:
A method of flip-chip mounting a semiconductor chip onto a mounting substrate, comprising the steps of: applying a resin material to a chip mounting part of the mounting substrate; sucking and holding the semiconductor chip by a pressure heat applying head, in which a surface for sucking the semiconductor chip is formed into a concave surface and a suction hole is opened at the center of the concave surface so as to bend the semiconductor chip upward or in a direction away from the chip mounting part of the mounting substrate; pressing the semiconductor chip onto the mounting substrate and heating the same, by the pressure/heat applying head, in a state where the semiconductor chip is bent upward by vacuum suction from the suction hole, so as to bond bumps of the semiconductor chip to connection pads of the mounting substrate, fill a gap between the semiconductor chip and the mounting substrate with the resin material and thermally harden the resin material.
