Abstract
Description
基板ホルダ20と、真空ポンプシステム30とを有することができる。基板25は、例えば、半導体基板、ウエハ又は液晶ディスプレイであることができる。プラズマプロセスチャンバ10は、例えば、基板25の表面に隣接しているプロセス領域15でのプラズマの発生を容易にするように設定されることができる。イオン化可能なガス又はガスの混合物が、ガス注入システム(図示されていない)により導入され、プロセス圧力が調整されている。例えば、コントロール機構(図示されていない)は、前記真空ポンプシステム30を調整するために用いられることができる。プラズマは、所定の材料プロセスに特有な物質を生成するため、並び/もしくは、基板25の表面の露出された表面から物質を除去を補助するために用いられることができる。前記プラズマプロセスシステム1aは、200mm基板、300mm基板、又は比較的大きい基板をプロセスするように設定されることができる。
ピーク間RF電圧を表しており、ここでr、rr、rrrは、前記自然酸化膜ブレークスルーステップと、メインエッチングステップと、オーバーエッチステップとのそれぞれの間の前記底部(下方)電極のピーク間電圧に対する従来の値を表している。そして、epdは、終点検出時間を表している。前記プラズマプロセスシステムの他の設定は、いくらか異なるパラメータ設定と値とを有している。
選択的なHfO2からSiO2へのエッチングに対して、HBrプラズマにおけるSiO2エッチングは、高い基板温度でイオンによる駆動(ion-driven)のエッチングとしてあり続け、一方でHfO2エッチングは、化学エッチングの特性の1つとなってくる。結果として、高い基板温度の下での低い下方電極RF電力条件は、比較的低い速度でSiO2をエッチングする一方で、高い速度でHfO2を化学的にエッチングすることができる。C2H4又はC2H4Br2添加剤の場合には、ポリマが前記Si-Oをイオン衝撃からさらに保護し、SiO2エッチング速度をさらに減速させることができる。
PPHにおけるトレース−Cl2は、表面汚染を妨げるためである。多くの場合に、プラズマプロセスシステムは、水晶構成要素を有することができる。例えば、純粋なHePPHにおける汚染は、前記水晶構成要素からのSiOを有することができる。前記PPHプロセスステップにおけるトレース−Cl2は、HfO2層の表面上にSiOが発生することを妨げることができる。代わりに、純粋なHePPHの間、BTプロセスステップ(ブレークスルー)は、前記DEステップの前に挿入されることができる。CF4BTは、高k誘電体材料表面からSiO2を除去することにおいて効果的であることが知られている。
