Abstract

본 발명은 반도체 장치의 폴리 실리콘막 식각시 발생할 수 있는 식각 잔유물을 완전히 제거할 수 있으며, 이를 통해 제조공정상의 수율 향상에 기여하는 효과가 있으며, 폴리 실리콘막을 식각하여기판상의 소정부위를 노출시키는 반도체 장치의 제조방법에 있어서, 상기 폴리 실리콘막의 주식각후 과도식각전, Hbr + SF6가스가 포함된 플라즈마를 사용하여 각각 잔유물을 제거하는 공정을 포함하여 이루어지는 것을 특징으로 한다.The present invention has the effect of completely removing the etching residue that may occur when a polysilicon film is etched in a semiconductor device, thereby contributing to improvement in the yield of the manufacturing process. And a step of removing the residues using a plasma containing Hbr + SF6 gas before the transient etching of the polysilicon film after the polysilicon film is etched.
