Abstract:
1. A wire bonding method that connects a first bonding point and a second bonding point by a wire, said method comprising, in the order stated, steps of: a step that press-bonds a ball formed on a tip end of a wire to a first bonding point, thus forming a press-banded ball; then a step that raises a capillary; then a step that moves the capillary toward a second bonding point; then a step that then lowers the capillary by an amount that is smaller than an amount in which the capillary was raised to form a bent portion in said wire; then a step that raises the capillary to allow the wire to be paid out of the capillary; and then a step that moves the capillary toward a second bonding point, thus connecting the wire to the second bonding point.
