本実施の形態を、図1、図3及び図4を用いて説明する。図1は、レーザ発振器501、複数の減衰器502a〜502c、光学系503、湿度制御チャンバー505、プロセスチャンバー504及び第1の移載手段(図示せず)を有するレーザ光照射装置500である。
また、減衰器502aを通過したレーザ光のエネルギーを変えずに、光路を任意に変更するためのものを有してもよい。代表的には、ミラーを用いることができる。
本実施の形態を図2を用いて説明する。実施の形態1と同じ構成物は、同じ符号を用いて詳細の説明を省略する。
本実施の形態では、実施の形態1又は実施の形態2とは異なり、不活性ガスを内部に導入することが可能な減衰器を有するレーザ光照射装置について図5を用いて示す。
本実施の形態では、加熱された減衰器を効率よく冷却することが可能なレーザ照射装置について図13を用いて示す。
本実施の形態では、より効率よく加熱された減衰器を冷却することが可能なレーザ照射装置について図14を用いて示す。
実施の形態1において、供給口と排出口の位置が異なるレーザ光照射装置を図15を用いて説明する。
実施の形態2において、供給口と排出口の位置が異なるレーザ光照射装置を図16を用いて説明する。
実施の形態3において、供給口と排出口の位置が異なるレーザ光照射装置を図17を用いて説明する。
本実施の形態においては、実施の形態1から実施の形態8に開示のレーザ光照射装置を用いて一定のエネルギーを有するレーザ光を照射することが可能なレーザ光照射装置及びレーザ光の照射システムについて説明する。本実施の形態では、実施の形態1のレーザ光照射装置を用いた例を示す。このため、実施の形態1と同じ構成物は、同じ符号を用いて説明する。本実施の形態では、被照射物の代表例として基板を用いるが、他の部材を適応できる。
これらの決定は、レーザ光照射装置制御装置917で行う。あらかじめレーザ光照射装置制御装置917のメモリで記憶されてある情報から、これらの値をそれぞれ決める。
