Zusammenfassung:The substrate processing method of the present invention is a substrate processing method for manufacturing a hard mask used in a photoresist film for EUV. The method includes the steps of: preparing a substrate on which a lower film is formed; forming a tin thin film containing oxygen on the substrate on which the lower film is formed; forming a tin thin film containing carbon on the tin thin film containing oxygen to improve adhesion with the photoresist film for EUV. 본 발명의 기판 처리 방법은 EUV 용 포토레지스트막에 사용되는 하드마스크를 제조하기 위한 기판 처리 방법으로서, 하부막이 형성된 기판을 준비하는 단계; 상기 하부막이 형성된 기판 상에 산소를 함유하는 주석 박막을 형성하는 단계; 상기 EUV 용 포토레지스트막과의 접합력을 향상시키 위하여 상기 산소를 함유하는 주석 박막 상에 탄소를 함유하는 주석 박막을 형성하는 단계; 를 포함한다.
