Description
図1は、本発明の第1実施形態に係る積層体の切断方法を体現するための切断装置を示す図である。この切断装置は、積層体1をレーザー溶断するものであって、レーザーLBを照射するレーザー照射装置5と、積層体1を支持する支持ステージ8とを備えている。なお、この実施形態では、積層体1に対してレーザーLBを上方から照射する。すなわち、積層体1において、上面がレーザーLBの入射側、下面がレーザーLBの反入射側となる。
積層体をレーザー溶断により切断する場合、溶断により発生したガラス及び樹脂の溶融異物が発生し、この溶融異物が積層体のガラス板の表面に付着し、ガラス板の表面が汚染されるおそれがある。汚染された場合、事後的に洗浄によってガラス板の表面から溶融異物を除去することも考えられるが、ガラス板の表面から溶融異物を完全に除去することは困難である。
また、積層体をレーザー溶断により切断し、製品部と非製品部に分離する場合、製品部を構成するガラス板の切断端面にマイクロクラック等の微小欠陥が形成される場合があった。このような不具合は、特に、厚みが数百μm以下程度にまで薄板化されたガラス板を含む積層体をレーザー溶断した際には、微小欠陥の形成頻度が一層増大した。そこで、本願発明者等は鋭意研究を重ね、その結果、レーザー溶断の実行中における積層体の支持態様が適当でない場合、特に、積層体のうち製品部(となる領域)よりも非製品部(となる領域)の方が僅かなりとも高位置にある場合に、製品部の切断端面に微小欠陥が形成され易いことが判明した、その概要を図5に基づいて説明する。
