Abstract
A wire bonding method used in a bonding apparatus manufacturing, for example, semiconductor devices makes a correction of the ultrasonic output of a transducer using one of three correction timing patterns: a first correction timing pattern which makes the ultrasonic output correction prior to a first bonding by a first bonding wire to a single IC device, a second correction timing pattern which makes the output correction prior to a first bonding by a bonding wire, and a third correction timing pattern which makes the output correction prior to a first bonding and prior to a second bonding. By selecting one of the three patterns, the ultrasonic oscillation output is corrected at an appropriate timing regardless of the differences in the characteristics of the transducers used.
