Description
第2ガス供給装置150がチャンバ110内に配される。第2ガス供給装置は、外部から第2反応ガスを流入して基板S上に供給する。一実施例によれば、第2ガス供給装置150は、間隔d1に第2反応ガスを噴出できるように配されうる。一実施例によれば、前記第2反応ガスは、ガス形態、または液体ソースを気化させた蒸気の形態でチャンバ110内部に提供されうる。一実施例によれば、前記第2反応ガスは、基板S上に結晶性薄膜が形成される間、気相から非結晶性物質が前記基板S上に形成されることを抑制するように基板S上で作用できる。前記第2反応ガスは、一例として、塩化水素のような17族元素を含む化合物ガスを含むことができる。第2反応ガスは、Cl系、F系のような反応性の強い元素を含むことができる。
[実験例]
図1と関連して前述の第1実施例の薄膜蒸着装置を利用し、基板上にシリコン薄膜を形成した。第1反応ガスとしては、10%濃度のシランを100sccm使用し、熱線構造体は、フィラメント型を使用した。前記熱線構造体を1,600℃の温度で加熱し、前記第1反応ガスを解離した。
[評価]
図7は、本発明の一実施例において、塩化水素ガスの流量によって異なって蒸着された薄膜を、ラマン分光器で測定した結果を示したグラフである。
