Abstract
본 발명은 이방성 에칭방법에 관한 것으로, 에치율을 향상시키고, 에칭 설비의 노화를 방지하며 파티클의 발생을 줄여 챔버내부의 오염을 방지하고 웨이퍼의 품질을 향상하는데 목적이 있다.The present invention relates to an anisotropic etching method, which aims to improve etch rate, prevent aging of an etching facility, reduce generation of particles, prevent contamination of a chamber, and improve quality of a wafer.
상기 목적을 달성하기 위한 본 발명은 기판위에 폴리실리콘을 도포하고 상기 폴리실리콘 위에 포토레지스트를 도포하여 노광 현상하여 패턴을 형성한 후 반응가스를 넣어 에칭하는 이방성 에칭방법에 있어서, 상기 반응 가스는 Cl2와 SF6와 N2의 혼합 가스인 것을 특징으로 한다.According to an aspect of the present invention, there is provided an anisotropic etching method in which polysilicon is coated on a substrate, a photoresist is coated on the substrate, exposure is performed to form a pattern, 2, and a mixed gas of SF 6 and N 2 .
