发明名称 Method for flip chip bonding and flip chip bonder implementing the same
摘要 <p>Provided are a laser flip-chip bonding method having high productivity and excellent bonding reliability and a flip-chip bonder employing the same. The flip-chip bonder includes: a bonding stage on which a substrate rests; a bonding head picking up a semiconductor chip and attaching the semiconductor chip to the substrate; and a semiconductor chip heating unit heating the semiconductor chip to a bonding temperature. The semiconductor chip heating unit includes: a laser light source; and a lens assembly refracting a laser beam emitted by the laser light source to a top surface of the semiconductor chip so that a central position of the laser beam varies across the top surface of the semiconductor chip.</p>
