[0002]集積回路(IC)素子の構造サイズは、4分の1ミクロン以下にまで小型化されているので、電気抵抗と電流密度は懸念と改善の分野になっている。多層配線技術は、コンタクト、プラグ、バイア、ライン、ワイヤ、その他の特徴部(構造要素)を含む高いアスペクト比の特徴部に形成された、IC素子中の導電性経路を与える。基板上に相互接続(配線)を形成するための典型的なプロセスは、一つ以上の層を堆積することと、一つ以上の特徴部を形成するためにこれらの層の少なくとも一つをエッチングすることと、これらの特徴部にバリア層を堆積することと、特徴部を充填するために一つ以上の層を堆積することと、を含む。典型的には特徴部は、下位の導電性層と上位の導電性層との間に配置された誘電体材料内に形成される。相互接続は、上位導電性層と下位導電性層とを接続するためにこの特徴部内に形成される。これらの相互接続特徴部の信頼度の高い形成は、回路の製造と、個別の基板とダイ(チップ)とにおける回路密度及び品質を改善するための止むことのない努力とにとって重要である。
[0010]本発明の上述の特徴を達成する仕方が詳細に理解できるように、上記に簡単に要約された本発明の更に特定の説明は、付属の図面に示された本発明の実施形態を参照することによって行われる。しかしながら、本発明が、他の同等に有効な実施形態にも適用可能であるので、付属の図面が本発明の単に典型的な実施形態を説明するものであって、したがって、本発明の範囲を限定するものと考えるべきでないことに留意すべきである。
