Abstract: 본 발명의 일 실시형태에서는, PZT 층 또는 BST 층을 패터닝하는 방법이 개시되어 있다.     예를 들면, PZT 층 또는 BST 층은 주요 에천트로서 보론 트리클로라이드 (BCl 3 ) 또는 실리콘 테트라클로라이드 (SiCl 4 ) 를 포함하는 플라즈마 공급 가스를 이용하여 티타늄 질화물 (TiN) 과 같은 고온 친화성 마스크를 통해 플라즈마 에칭된다.     BCl 3 또는 SiCl 4 가 에천트 플라즈마 소스 가스로서 단독으로 이용될 수도 있지만, 통상적으로는, 본질적으로 불활성인 가스와 조합하여 이용된다.     본질적으로 불활성인 가스는 아르곤인 것이 바람직하다.     이용될 수 있는 다른 가능한 본질적으로 불활성인 가스는 크세논, 크립톤 및 헬륨이다.     어떤 경우에는, O 2 , N 2 , Cl 2 또는 이들의 조합물이 주요 에천트에 첨가되어, 고온 친화성 마스크 재료와 같은 인접한 재료에 대한 PZT 또는 BST의 에칭률을 증가시킬 수도 있다.     TiN 마스크 재료는 하부 산화물에 손상을 주지 않으면서 용이하게 제거될 수 있다.      통상적으로, TiN 마스크의 에칭률에 대한 PZT막의 에칭률의 비는 20 : 1 보다 우수하기 때문에, TiN에 대한 PZT 또는 BST의 선택도는 매우 우수하다.      또한, 통상적으로, BCl 3 함유 플라즈마 소스 가스를 이용한 PZT의 에칭률은 분당 2000 Å을 넘는다.     기판 바이어스 전력은 BCl 3 또는 SiCl 4 로부터 발생되는 이온을, 에칭되어질 표면을 향하여 안내하기 위해 인가된다.     바이어스 전력은 PZT층과 접촉하는 도전성 층 또는 도전성 층들의 스퍼터링을 방지하도록 제어되어, 에칭된 PZT층의 표면이, 패터닝된 PZT를 포함하는 반도체 장치의 단락을 야기할 수 있는 도전성 재료에 의해 오염되지 않게 한다.
