- 第1ボンド点と第2ボンド点との間をワイヤで接続するワイヤループ形状を有する半導体装置であって、
前記ワイヤの先端に形成したイニシャルボールをキャピラリによって前記第1ボンド点に接合させて形成された圧着ボールとボールネックと、前記ボールネックの上に折り返され、前記圧着ボールの直径よりはみ出さない押し付け部と、前記押し付け部と前記第2ボンド点との間の前記ワイヤと、前記ワイヤと前記第2ボンド点との接合部とを含み、
前記ボールネックは、前記イニシャルボールを前記キャピラリによって前記第1ボンド点に接合させた後、前記キャピラリを上昇させ、続いて前記キャピラリを前記第2ボンド点と反対の方向に向かって移動させた後、前記キャピラリを降下させて前記キャピラリの前記第2ボンド点側の第1のフェイス部で前記第2ボンド点側の前記ボールネックの一部が踏み付けられて前記圧着ボールよりも直径が小さい円板状に形成された平面を有し、
前記押し付け部は、前記キャピラリを降下させて前記第2ボンド点側の前記ボールネックの前記一部をその表面が平面状になるまで踏み付けた後、前記キャピラリを上昇させ、続いて前記キャピラリの前記第2ボンド点と反対側の第2のフェイス部が前記ボールネックの上に来るまで前記キャピラリを前記第2ボンド点に向かって移動させて前記第2ボンド点に向かって前記ワイヤを折り返し、その後前記キャピラリを降下させて踏み付けられて平面状となった前記ボールネックの前記一部の上に前記ワイヤを折り返し、前記ワイヤの側面を前記キャピラリの前記第2ボンド点と反対側の前記第2のフェイス部で押し付けて形成され、
前記押し付け部と前記第2ボンド点との間の前記ワイヤは、前記ワイヤの前記側面を前記キャピラリの前記第2ボンド点と反対側の前記第2のフェイス部で押し付けた後、前記キャピラリを前記第2ボンド点に向かって斜め上方に移動させ、その後前記キャピラリを上昇させ、続いてキャピラリを第2ボンド点と反対側に移動させるリバース動作を少なくとも1回行い、その後更にキャピラリを上昇させ、前記キャピラリを前記第2ボンド点の方向に移動させることにより形成される下に凸の湾曲部と前記下に凸の湾曲部の前記第2ボンド点側の上に凸の屈曲部とを含み、
前記ワイヤと前記第2ボンド点との接合部は、前記キャピラリを更に前記第2ボンド点に移動させて前記ワイヤを前記第2ボンド点に圧着させて接合することにより形成され、
前記ボールネックの前記平面は、その面積が増加するように、前記イニシャルボールを前記キャピラリによって前記第1ボンド点に接合させた後、前記キャピラリを上昇させ、続いて前記キャピラリを前記第2ボンド点と反対の方向に向かって移動させた後、前記キャピラリを降下させて前記キャピラリの前記第2ボンド点側の前記第1のフェイス部で前記第2ボンド点側の前記ボールネックの前記一部の第2ボンド点と反対側の他の一部をその表面が平面状になるまで踏み付ける連続動作を複数回繰り返して形成されること、
