Abstract
【解決手段】レーザアニール装置1は、少なくとも被照射体7におけるレーザ照射領域に不活性ガスGを供給するガス供給装置10と、不活性ガスGの温度を調整するガス温調装置15とを備える。ガス温調装置15は、不活性ガスGの温度と、不活性ガスの供給領域の外側であってレーザ光の光路を囲む空間(部屋R)の雰囲気温度との温度差が小さくなるように、レーザ照射領域に供給される不活性ガスGの温度を調整する。

Description
特許文献2では、上下にスイングするスイングノズルの先端から窒素を噴出して、レーザ照射部分の近傍のみを窒素雰囲気とすることで、アニール処理中のシリコンの酸化を防止するようになっている。
特許文献3では、上部がガラスで密閉され下部が開放された円筒状のセルを基板に対して十分近接した位置に配置した状態で、セルの内部に窒素ガスを注入することで、アニール中のシリコンの酸化を防止するようになっている。
(1)被処理体にレーザ光を照射することにより被処理体をアニール処理するレーザアニール装置であって、少なくとも被照射体におけるレーザ照射領域に不活性ガスを供給するガス供給装置と、不活性ガスの温度を調整するガス温調装置と、を備え、該ガス温調装置は、不活性ガスの温度と、該不活性ガスの供給領域の外側であってレーザ光の光路を囲む空間の雰囲気温度との温度差が小さくなるように、レーザ照射領域に供給される前記不活性ガスの温度を調整する、ことを特徴とする。
