Abstract:
Provided are a flip chip laser bonding apparatus and a flip chip laser bonding method, and more particularly, to an apparatus and method for flip chip laser bonding, in which a semiconductor chip in a flip chip form is bonded to a substrate by using a laser beam. According to the flip chip laser bonding apparatus and the flip chip laser bonding method, even a semiconductor chip that is bent or is likely to bend may also be bonded to a substrate without contact failure of solder bumps by bonding the semiconductor chip to the substrate by laser bonding while pressurizing the semiconductor chip.

Claim (Index 1):
A flip chip laser bonding apparatus, comprising:\n a fixing member configured to fix a lower surface of a substrate, wherein a plurality of semiconductor chips to be bonded to an upper surface of the substrate are arranged on the substrate; a pressing member arranged above the fixing member, the pressing member comprising a transparent portion through which a laser beam penetrates; a lifting member configured to lift or lower one of the fixing member and the pressing member relative to the other of the fixing member and the pressing member such that at least some of the plurality of semiconductor chips that are pressurized are pressurized against the substrate; and a laser head configured to irradiate the laser beam to the pressurized semiconductor chips between the pressing member and the fixing member through the transparent portion of the pressing member so as to bond solder bumps of the semiconductor chips and solder bumps of the substrate to each other.
