Abstract

A system for laser bonding of flip chip, and more particularly, to a system for laser bonding of flip chip for bonding a flip chip-type semiconductor chip to a substrate by using a laser beam is provided. According to the system for laser bonding of flip chip of the present disclosure, by performing laser bonding on a substrate while pressurizing semiconductor chips, even semiconductor chips which are bent or likely to bend may be bonded to the substrate without causing poor contact of solder bumps.
