- 반도체소자의 게이트 산화막 형성방법에 있어서, 웨이퍼를 650℃의 튜브를 장착하는 단계와, 상기 튜브의 온도를 700~800℃로 상승시키는 단계와, 상기 온도에서 웨이퍼상에 DCE를 산화원으로 이용하여 게이트 산화막을 형성하는 단계와, 상기 튜브의 온도를 800~900℃로 상승시켜 어닐링한 후 웨이퍼를 언로딩시키는 단계를 포함하는 반도체소자의 게이트 산화막 형성방법.
- 제1항에 있어서, 상기 게이트 산화막 형성공정을 O2: H2: DCE=8/8/0.14(SLPM) 분위기에서 진행되는 것을 특징으로 하는 반도체소자 게이트 산화막 형성방법.
- 제1항에 있어서, 상기 어닐링 공정시 N2/LO2=2.5/0.5(SLPM) 분위기에서 온도를 상승시킨 후, N2=25(SLPM) 분위기에서 어닐링하는 것을 특징으로 하는 반도체소자의 게이트 산화막 형성방법.
- 제1항에 있어서, 상기 게이트 산화막을 100Å 두께로 형성하는 것을 특징으로 하는 반도체소자 게이트 산화막 형성방법.
