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。
該平行対向体の上流側側部に取り付けられ、平行対向体と被処理体の表面との間に被処理体の表面に沿って一方向に不活性ガスが供給されるように被処理体に向って不活性ガスを吹き付けるパージユニットとを備え、前記ガス温調装置は、パージユニットより上流側の位置で不活性ガスの温度を調整する。

- 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、
前記ガス供給装置は、前記被処理体の表面に平行な下面を有し、かつ該下面を形成する底部にレーザ光を透過させる透過窓を有する平行対向体と、
該平行対向体の上流側側部に取り付けられ、平行対向体と被処理体の表面との間に被処理体の表面に沿って一方向に不活性ガスが供給されるように被処理体に向って不活性ガスを吹き付けるパージユニットとを有し、
前記ガス温調装置は、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、前記パージユニットより上流側の位置で、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、ことを特徴とするレーザアニール装置。
