Abstract:
1. A method of flip-chip mounting a semiconductor chip that places bumps of the semiconductor chip and pads of a substrate in contact, flip-chip bonds the semiconductor chip to the substrate, and fills a space between the semiconductor chip and the substrate with an insulating adhesive, comprising: a step of providing a hardening trigger that is not heat to the insulating adhesive before the semiconductor chip is mounted on the substrate or during bonding; and a step of bonding the bumps of the semiconductor chip to the pads of the substrate by pressure welding or metal combining while hardening of the insulating adhesive is progressing due to the hardening trigger having been provided, wherein a two-part hardening resin is used as the insulating adhesive and the method further comprises: a step of applying one liquid out of the two-part hardening resin onto a mounting position on the substrate and then mixing another liquid out of the two-part hardening resin with the one liquid; and a step of positioning and disposing the semiconductor chip on the substrate onto which the two-part hardening resin has been applied and bonding the bumps of the semiconductor chip to the pads of the substrate.
