Abstract

A wire bonding method comprises: preparing a wire bonding apparatus; a step of forming a free air ball; a first height measuring step of measuring the height of a first electrode by detecting whether the free air ball is grounded to the first electrode; a second height measuring step of measuring the height of a second electrode by detecting whether the free air ball is grounded to the second electrode; a first bonding step of controlling the height of a bonding tool based on the measurement result in the first height measuring step, and bonding the free air ball to the first electrode; and a second bonding step of controlling the height of the bonding tool based on the measurement result in the second height measuring step, and bonding a wire to the second electrode to connect the first and the second electrodes. Thus, electrodes can be correctly bonded.
