Description

図1は本発明の一実施形態に係るプラズマ成膜方法が適用可能なプラズマ成膜装置の一例を示す断面図である。図1のプラズマ処理装置は、RLSA(登録商標)マイクロ波プラズマ成膜装置として構成されており、被処理体である半導体ウエハ(以下単に「ウエハ」と記す)にプラズマCVDにより窒化珪素(SiN)膜を成膜するようになっている。
次に、このように構成されるプラズマ成膜装置100を用いたプラズマ成膜方法の一実施形態について図2のフローチャートを参照して説明する。
マイクロ波発生装置39からの所定のパワーのマイクロ波を、マッチング回路38を経て導波管37に導く。導波管37に導かれたマイクロ波は、矩形導波管37bをTEモードで伝播される。TEモードのマイクロ波はモード変換器40でTEMモードにモード変換され、TEMモードのマイクロ波が同軸導波管37aをTEMモードで伝播される。そして、TEMモードのマイクロ波は、遅波材33、平面アンテナ31のスロット32、およびマイクロ波透過板28を透過し、チャンバー1内に放射される。

SiH4ガス流量:10〜200mL/min(sccm)
N2ガス流量:10〜200mL/min(sccm)
マイクロ波パワー密度:0.01〜0.04W/cm2
次に、実験例について説明する。
ここでは、図1に示すプラズマ成膜装置を用いてプラズマCVDによりSiN膜を成膜するにあたり、プラズマ生成ガスとしてHeガスを添加しない場合とHeガスを添加した場合について膜厚均一性を比較した。
SiH4ガス流量:90sccm
N2ガス流量:70sccm
マイクロ波パワー密度:2.78W/cm2
処理時間:80sec
SiH4ガス流量:10〜200sccm
N2ガス流量:5〜200sccm
