Description
本発明は、概して、ポリシリコンフィーチャをパターンニングするために、アモルファスカーボンのハードマスク層上に二酸化シリコンのキャップ層を形成するための方法に関する。本発明は、以下の説明に限定されることなく、370℃以下の温度でプラズマエンハンスト化学気相成長法によって形成された二酸化シリコン層を提供することによって、最終的に得られるポリシリコンフィーチャの欠陥を実質的に減らすことができると考えられている。この発見に基づいて、下層のアモルファスカーボン層とともに、所望の光学特徴を提供するために求められる、二酸化シリコン層の厚さを5−50nmの範囲内で確実に制御することができるように、二酸化シリコン層を形成するためのプラズマエンハンストCVDプロセスが設計される。一般的に、低温での堆積速度を速めることができるTEOSベースのプラズマエンハンストCVDプロセスは、本発明では、欠陥率の低減が求められるので、ある実施形態では、層厚を確実に制御し、その結果、二酸化シリコン/アモルファスカーボン積層体の光学特徴を確実なものにするために、堆積速度を低下させるように堆積処理を制御する。
以下の詳細な説明と図面に例示されているように、実施形態を用いて本発明を記載したが、以下の詳細な説明と図面は本発明を開示されている特定の例示的実施形態に限定することを意図とするものではなく、むしろ、説明した例示的な実施形態は単に本発明の様々な形態を例証するものであって、本発明の範囲は添付の請求の範囲によって定義される。
更に、実際の堆積処理中に使用されているように、堆積中に搬送ガスと反応ガスを供給する吹き出し口に対する基板201の距離を所望の値に調節することができる。更に、ヘリウムなどの搬送ガスを導入してもよく、また続いて、圧力を実際の堆積ステップの間における圧力よりも非常に高い圧力である約10Torr未満に調整する間に、ガス雰囲気に酸素を供給することもできる。
8〜12秒間、ガスを供給しない状態で、約300℃の温度で基板201の雰囲気を安定化させるステップ;
ガスを流さずに、約8〜約12秒間、堆積温度で温度を維持しながら、堆積における構造と一致するように対応するプロセスチャンバの構造を定める、すなわち、ガスの噴射口と基板210との距離を定めるステップ;
堆積時の流量に実質的に対応する流量で、約4〜約6秒間、ヘリウムを導入するステップ;
例えば、約3000sccmの堆積時の流量で、約9Torrに昇圧し、約8〜約12秒間、酸素を供給してガス雰囲気を確立するステップ;
周囲圧力を、例えば約5.5Torrの堆積圧力にまで下げながら、例えば、毎分、750mg〜850mgの供給増加速度でTEOS供給を起動させるステップ;
残りのパラメータを実質的に一定に保ちながら、約13〜約17秒間、供給速度を毎分約450mg〜550mgに減速することによって、ガス雰囲気220が含むTEOSの量を所望の堆積量に調整するステップ;
最終的な二酸化シリコンの厚さが約5nm〜50nmの範囲となるように、約3〜約8秒の時間間隔内で堆積時間を制御しながら、実質的にパラメータが一定のプラズマ雰囲気220Aを確立するステップ;
TEOSの供給とプラズマの生成を中断する一方で、2〜5秒間、ヘリウムの流量を約1000sccm〜1200sccmへ、また、酸素の流量を約1200sccm〜1400sccmへ調節して、ヘリウムと酸素の流量を減らすステップ;
ヘリウムの供給は維持しながら酸素の供給を中断する、もしくは、反応副産物のポンプ処理を継続しながら、ヘリウムの流量を約1200sccm〜1400sccmに増加させるステップ;
副産物を取り除きながら、全てのガス供給を約9〜約13秒間中断するステップ、を含むことができる。
