Abstract
건식식각 후 형성되는 폴리머(Polymer)를 제거하는 반도체 건식식각방법에 관한 것이다.And a semiconductor dry etching method for removing a polymer formed after dry etching.
본 발명은 반도체 건식식각공정이 이루어진 웨이퍼 상의 포토레지스트를 스트리핑한 후 잔존하는 폴리머(Polymer)를 제거하도록 표면을 플루오르화수소처리함을 구비하여 이루어진다.The present invention comprises stripping a photoresist on a wafer subjected to a semiconductor dry etching process and then subjecting the surface to hydrogen fluoride treatment to remove the remaining polymer.
따라서, 반도체 소자 제조 후 폴리머가 절연체로 작용하여 반도체 소자가 전기에 도통되지 않는 문제점을 해결할 수 있다.Accordingly, it is possible to solve the problem that the polymer acts as an insulator after the semiconductor device is manufactured and the semiconductor device does not conduct electricity.
