Si2H6+e‐ → SiH3+SiH2+H+e‐(2)
本発明の一実施形態によれば、孔の断面積は、100mm2〜10000mm2、好ましくは500mm2〜4000mm2である。
実施例1および2
本発明による長さ10cm(プラズマ長)のステンレス鋼中空電極を2つ有するプラズマ源を構築し、以下の条件で100時間より長く動作させた。
・周波数40kHz
・電圧機能:バイポーラ、電圧制御で正弦波
・電力セットポイント20kW、プラズマ源を電力制御モードで動作させる
・プラズマを形成するガスO2;流量は孔長1リニアミリメーターあたり2sccm
・陰極孔の断面積2000mm2
・真空チャンバの圧力:8〜12mTorr
・出口ノズルの幅:3.5mm
孔の表面でのスパッタリングは、デブリ粒子の形成につながる。24時間間隔で、ガラス基材上のデブリを回収し、デブリ粒子の数を計数した。以下の表から明らかなように、デブリ粒子の数は、円形の形状よりも角に丸みのある矩形の孔の断面形状で、かなり短時間で増加した。
実施例3〜17では、中空陰極プラズマ源をシミュレートした。
・周波数100kHz
・電圧機能:バイポーラ、電圧制御で正弦波
・電力セットポイント25kW/m
・壁温度300K
・原料ガス種Si2H6 流量は孔長1リニアメーターあたり0.13sccm
・プラズマを形成するガスAr 流量は孔長1リニアメーターあたり2.65sccm
・二次電子放出係数が0.1の電極材料(Ag、Cu、Al、Ti、Zn、Feに匹敵)
・真空ポンプをチューニングすることにより、真空チャンバの圧力約10mTorr
