Filed: 2000-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor chip mount, capable of improving productivity of flip-chip bonding, and to provide a bonding tool. SOLUTION: The method for manufacturing the semiconductor chip mount comprises the steps of designating the hardness of surface of the bonding tool 14 contacted with the chip 11 at a bonding time, and setting the hardness to a Vickers hardness of a value equivalent to or of substantially 1.7 time as large as a hardness of the chip 11.
