Abstract
Description
도 2는 퍼플루오로트리-n-부틸아민(perfluorotri-n-butylamine)의 고분자(polymer) 오염 물질 제거 성능을 테스트한 결과를 보여주는 사진이다.
도 3은 본 발명에 따른 반도체 공정 챔버 내 오염물 세정용 패드로서, 일면은 퍼플루오로트리-n-부틸아민(perfluorotri-n-butylamine) 용액이 함침된 폴리우레탄 스폰지(PU sponge)로 이루어지고, 타면은 사포(sand paper)로 이루어진 세정용 패드의 사진이다.
도 4는 도 3에 도시한 본 발명에 따른 세정용 패드를 사용해 고분자(polymer) 오염 물질을 제거하는 과정을 보여주는 사진으로서, 세정용 패드의 고분자 폼층(폴리우레탄 스폰지)을 이용한 세정제 조성물 도포(wetting)와 연마층(사포)을 이용한 고분자(polymer) 오염 물질 문질러 닦기(scrubbing)를 번갈아 실시해 기재 표면의 오염 물질이 제거되는 과정을 보여준다.
