Abstract
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 chipincludes a step of providing a hardening trigger that is not heat to insulating adhesiveeither before the semiconductor chipis mounted on the substrateor during bonding; and a step of bonding the bumps of the semiconductor chip to the pads of the substrateby pressure welding or metal combining while hardening of the insulating adhesiveis progressing due to provision of the hardening trigger.
