In this wire bonding, one end of a wire such as a gold wire is bonded to an external connection electrode of a semiconductor element by a capillary tool, and the wire in the bonded state is moved by a capillary tool to form a bond on a circuit electrode of a substrate. The wire is drawn to the point and bonded. Since the bonding target surface needs to be heated in advance during bonding depending on the bonding target, the substrate mounting portion on which the substrate is mounted has a heating unit such as an electric heater. Therefore, when high-temperature bonding is required, radiant heat from the substrate heated by the substrate mounting portion is transmitted to the horn, and the temperature of the horn rises.

く、ボンディング不良を招く原因となっていた。However, since the capillary tool for holding the bonding wire is mounted on the tip of the horn supported in a cantilever state, the position tends to fluctuate due to a temperature change of the horn. For this reason, when bonding is performed while heating the substrate, the bonding position of the capillary tool is likely to be displaced, which has caused a bonding failure.

6, the wire 15 is released from the clamped state, and the capillary tool 13 is lowered to press the ball 20 against the external connection electrode on the upper surface of the chip 3 for bonding. Next, as shown in FIG. 4A, the capillary tool 13 is raised, and when the capillary tool 13 reaches the highest point, the cut clamper 16 is closed. Then, in this state, the capillary tool 13 is moved above the circuit electrode 5 of the substrate 2, and the lower end of the capillary tool 13 is lowered while drawing a predetermined trajectory to form a loop of the wire 15, and FIG. The wire 15 is pressed against the circuit electrode 5 of the substrate 2 for bonding as shown in FIG.

することができる。In this wire bonding operation, the substrate 2 is heated by a heater built in the substrate mounting portion 1, and the temperature is rising. Therefore, heat is radiated upward from the substrate 2, and the surrounding components and mechanisms are heated by the radiated heat. Even in this state, the radiant heat radiated to the horn 12 by the heat shield plate 20 is mostly shielded, and furthermore, the heat shield plate 20 itself is always cooled by the cooling air from the nozzle pipe 21. 12 does not rise excessively. Therefore, no displacement of the capillary tool 13 due to thermal deformation of the horn 12 occurs, and good bonding accuracy can always be ensured.
