Description
クラックが発生することなく穴あけするレーザ加工方法として、例えば、特許文献1には、保護シートが貼られたガラス基板の穴あけ位置に保護シート側から炭酸ガスレーザを照射して未貫通穴を形成し、ガラス基板から保護シートを除去してアニーリング処理を行い、ガラス基板のレーザの非照射側を研磨処理して前記未貫通穴を貫通穴に変えるレーザ加工方法が開示されている。
しかしながら、最終的な貫通穴の径はレーザの非照射側で小さくなり、穴に導電メッキする場合、この部分でのメッキ付着特性が悪くなる欠点がある。
先ず第1の工程として、図1(a)に示すように穴あけを行うべきガラス基板1の表面に保護シート2を貼ったワーク基板3を用意する。ガラス基板1は例えば無アルカリガラスを材料とするものであり、保護シート2は接着剤をガラス基板1側に残さずに容易に剥がせるものである。
AOM駆動信号Dは、それがオンの時間帯でのみAOM23に入力されたレーザパルスL1を加工方向に分岐させてレーザパルスL2とし、それ以外の時間帯では非加工方向のレーザパルスL3としてダンパ25の方向に分岐させる。
ガルバノ動作制御信号Gは、オフの時間帯でガルバノスキャナ24を静止させ、オンの時間帯でガルバノスキャナ24を回転させる。ガルバノスキャナ24が静止した状態で一つの穴位置にレーザが照射され、ガルバノスキャナ24が回転することによってレーザパルスL2を次の穴位置に照射させるようになる。
このエッチング処理を行ってから保護シート5を剥がした後の様子を図1(e)に示すが、レーザの非照射側がエッチングされ、穴あけ位置に貫通穴6が形成されたガラス基板1が完成する。

Claims (2)
- 炭酸ガスレーザを用いてガラス基板に穴あけするレーザ加工方法において、前記ガラス基板のレーザ加工に対する第1保護シートが貼られた片方の面側から前記レーザを照射して未貫通穴を形成する工程と、前記ガラス基板から前記第1保護シートを除去してアニーリング処理を行う工程と、前記ガラス基板のレーザ照射面側に湿式エッチング処理に対する第2保護シートを貼って前記未貫通穴が形成された前記ガラス基板の前記レーザの非照射面側だけを穴の断面形状がX形になるまで湿式エッチング処理して前記未貫通穴を貫通穴に変える工程と、を有し、
前記貫通穴は、前記レーザ加工が施された部分と、前記湿式エッチング処理が施された部分と、を含むことを特徴するレーザ加工方法。 - 請求項1に記載のレーザ加工方法において、前記未貫通穴の形成工程においては、各穴位置毎にレーザパルスを1個ずつ照射しながら穴位置を移動させ、全ての穴位置について完了したら、必要な回数だけ同じ動作を繰り返すサイクル加工で行うことを特徴とするレーザ加工方法。
