Description
[0001]この出願は、2019年11月1日に出願された米国特許出願第62/929,291号の優先権の利益を主張し、その内容は、あらゆる目的のためにその全体が参照により本明細書に組み込まれる。
[0002]本技術は、半導体堆積プロセスに関する。より具体的には、本技術は、応力効果が低減された材料を堆積する方法に関する。
[0003]集積回路は、基板表面に複雑にパターン化された材料層を生成するプロセスによって可能になる。基板上にパターン化された材料を製造するには、露出した材料の形成と除去の制御された方法が必要である。製造されたフィルムの材料特性は、基板効果に寄与する可能性があり、処理中にウエハの反りやその他の問題を引き起こす可能性がある。
