Patent ID: 7927997

Claim:
A flip-chip mounting method in which a semiconductor chip having a plurality of electrode terminals is aligned to oppose a circuit board having a plurality of connection terminals for electrically connecting said connection terminals of said circuit board and said electrode terminals of said semiconductor chip to each other, comprising the steps of: holding said semiconductor chip to oppose said circuit board with a given gap provided therebetween; dipping said semiconductor chip and said circuit board held with the given gap in a dipping bath containing a melted resin including melted solder particles; and after the step of dipping, taking said conductor chip and said circuit board out of said dipping bath and curing said melted resin having permeated into the gap between said semiconductor chip and said circuit board, wherein in the step of dipping, said melted solder particles self-assemble between said connection terminals of said circuit board and said electrode terminals of said semiconductor chip, whereby forming connectors between said terminals, and the step of dipping is performed while rocking said semiconductor chip and said circuit board held with the given gap within said dipping bath.
