Patent ID: 7531387

Claim:
A flip chip mounting method for disposing a semiconductor chip having a plurality of electrode terminals in facing relation to a circuit board having a plurality of connecting terminals and electrically connecting the connecting terminals of the circuit board to the electrode terminals of the semiconductor chip, the flip chip mounting method comprising: a first step of supplying a resin containing a solder powder and a gas bubble generating agent to a space between the circuit board and the semiconductor chip; a second step of heating the resin to generate gas bubbles from the gas bubble generating agent contained in the resin; and a third step of heating the resin to melt the solder powder contained in the resin, wherein, in the second step, the resin is pushed toward the outside of the gas bubbles generated from the gas bubble generating agent by growth of the gas bubbles and self-assembled between the connecting terminals of the circuit board and the electrode terminals of the semiconductor chip and, in the third step, the solder powder contained in the resin self-assembled between the terminals is melted to form connectors between the terminals.
