Description
発明の分野
この発明は、一般に半導体製造の分野に関する。より具体的には、本発明は基板上に金属膜を堆積させるための新規前駆体に関する。
ALDおよびCVDは、スパッタリング、分子線エピタキシー、およびイオンビーム打込みなどの物理気相堆積(PVD)のような他の堆積方法と比較して、金属膜の堆積のために特に有用な技術である。ALDおよびCVDは、所望される製品を提供するために要求される加工段階の数を減らせる可能性を含む、電子デバイス製造の設計に柔軟性を与えるためにも使用され得る。これらの技術は、共形堆積、銅、銀、金および他の材料の堆積についての選択的な堆積を可能にする。金属膜を形成するために適切なプロセスは、熱的に安定で、容易に気化し、反応性があり、きれいな分解性を持つような、厳しい条件を要する適切な前駆体の同定を必要とする。
金属膜を堆積させるための新規前駆体組成物がここに開示される。一般に、開示された組成物は、銅、金、銀などを含む前駆体化合物を利用する。より具体的には、開示された前駆体化合物は、熱安定性を増大させるために金属(例えば、銅、金、銀)と結合されたペンタジエニル配位子を利用する。さらに、銅、金、銀を堆積させるための方法が、金属膜を堆積させるための他の前駆体の使用とともに開示される。方法および組成物が種々の堆積プロセスにおいて使用され得る。開示された化合物は、室温での熱安定性のようないくつかの利点を持つ。さらに、開示された前駆体は有毒なリン化合物を含まない。該方法および組成物の他の側面は以下でより詳細に記述されるであろう。
いくつかの用語は、特定の系の要素に言及するために以下の記載および請求項に渡って使用される。本文は、名称が異なるが機能が異ならない要素を区別することを意図したものではない。
一つの態様において、金属膜の堆積のための前駆体は、式(Op)x(Cp)yMR’ 2-x-yを持つ有機金属化合物を含む。ここで使用されるように、用語「有機金属」は、金属-炭素結合を含む化合物または分子を指し得る。Mは任意の適切な金属であり得る。特に、Mは、限定されないが、銅(Cu)、銀(Ag)または金(Au)のような任意の第11族金属元素を含み得る。他の適切な金属はルテニウムまたはタンタルを含む。Opは、置換されているかまたは無置換の、開いたペンタジエニル配位子である。さらに、Cpは、同じく置換されているかまたは無置換であり得るシクロペンタジエニル配位子である。添え字xはOp配位子の数を示す整数であり、1である。添え字yはCp配位子の数を示す整数であり、0から1までの範囲にある。
