Patent ID: 10734259

Abstract:
A flip-chip bonding apparatus (100) is provided with: a bonding tool (10) that includes a base (11), and an island (13) that vacuum-sucks, to a surface (14) thereof, a semiconductor die (70) having protruding electrodes (72, 73) that are disposed on both the surfaces; and a heater (20) that heats the semiconductor die (70) vacuum-sucked to the island (13). The flip-chip bonding apparatus heats the semiconductor die (70), bonds the protruding electrodes (73) of the semiconductor die (70) to protruding electrodes (82) of a semiconductor die (80), and seals, using a non-conductive film (NCF) (75), a gap between the semiconductor die (70) and the semiconductor die (80). Continuous vacuum suction holes (15) are provided in the base (11), said continuously vacuum suction holes being at positions adjacent to the outer peripheral surface of the island (13).
