A method of flip-chip mounting a semiconductor chip can carry out bonding at normal temperature and improves the positional accuracy of bonding. The method of flip-chip bonding a semiconductor chip 52 includes a step of providing a hardening trigger that is not heat to insulating adhesive 51 either before the semiconductor chip 52 is mounted on the substrate 50 or during bonding; and a step of bonding the bumps of the semiconductor chip to the pads of the substrate 50 by pressure welding or metal combining while hardening of the insulating adhesive 51 is progressing due to provision of the hardening trigger.

A method of manufacturing a semiconductor device flip-chip bonds electrode terminals of a substrate and a semiconductor chip together by solid-phase diffusion and underfills a gap between the substrate and the semiconductor chip with a thermosetting resin without the bonds between the terminals breaking due to heat in an underfill hardening step. The method includes a bonding step of flip-chip bonding the electrode terminals of the substrate and the semiconductor chip by solid-phase diffusion, an underfill filling step of filling the gap between the substrate and the semiconductor chip with the underfill material, and the underfill hardening step where the underfill material is heated to the hardening temperature to harden the underfill material. During the underfill hardening step, a member with a lower coefficient of thermal expansion out of the substrate and the semiconductor chip is heated to a higher temperature than the other member.

When a semiconductor chip is mounted using ultrasonic vibration, a method of mounting makes it possible to bond the semiconductor chip and bonding patterns with sufficient bonding strength without making the construction of a circuit board complex. The method of mounting a semiconductor chip causes ultrasonic vibration to act on the semiconductor chip to mount the semiconductor chip on a circuit board by flip-chip bonding. As the circuit board, a circuit board is used where protrusion patterns are provided at positions on bonding patterns to which the semiconductor chip is bonded corresponding to antinodes of vibration for a case where the bonding patterns resonate due to ultrasonic vibration applied by the semiconductor chip.

A method of bonding flying leads produces reliable bonds between the flying leads and substrate pads and can efficiently bond a plurality of flying leads and a plurality of substrate pads using a bonding tool. Flying leads are respectively aligned with a plurality of substrate pads disposed in parallel and a bonding tool applies ultrasonic vibration to the flying leads to bond the respective substrate pads and the flying leads. Bonding is carried out using a bonding tool in which (at least one contact member) a plurality of contact members that contact(s) the flying leads and apply (applies) the ultrasonic vibration thereto are (is) rotatably supported. The bonding tool is moved in a direction so as to cross the flying leads disposed in parallel with the plurality of contact members (at least one contact member) rolling while in contact with the flying leads, and the ultrasonic vibration is applied from the plurality of contact members (at least one contact member) to the flying leads to ultrasonically bond the respective flying leads to the substrate pads.
