Description
図3に示すように、第1ボンド点である半導体チップ110の電極112と、第2ボンド点である基板120の電極122とをワイヤで接続する(S10)。
第2ボンド点でのボンディングを終えた後、図3に示すように、ワイヤ42を繰り出しながらボンディングツール40を高さZ1まで上昇させるとともに第2ボンド点から第1ボンド点側に向かう方向に移動させて、ボンディングツール40の先端から延出したワイヤ42のうち第2ボンド点付近に被切断部92を形成する(S11)。例えば、図6に示すように、時刻t1にZ駆動機構12を作動させてボンディングツール40を上昇させ、次にXY駆動機構10を作動させてボンディングツール40を第1ボンド点側に向かう方向(図4(B)ではY方向)へ移動させることによってボンディングツール40を第1ボンド点側に向かって斜め上方に移動させ、時刻t2において図4(B)に示すようにボンディングツール40を高さZ1に配置する。この場合、図4(A)から図4(B)へのボンディングツール40におけるY方向の移動量は、適宜調整可能であり、例えばワイヤ径程度の大きさであってもよい。図4(B)に示すように時刻t2においては、ワイヤの被切断部92は、ボンディングツール40がY方向に移動してワイヤが屈曲することによって形成された屈曲部となっている。また、ワイヤの被切断部92は、第2ボンド点付近である、ワイヤと電極との接合部90付近に設けられる。
被切断部92の塑性変形を終えた後、ワイヤ42を繰り出しながらボンディングツール40を上昇させる(S14)。具体的には、図5(B)及び図6に示すように、時刻t5においてワイヤクランパ44を開いた状態で、Z駆動機構12を作動させてボンディングツール40を上昇させる。これによって、ボンディングツール40の先端からワイヤ42を延出させる。
