- 보트에 적재된 다수의 웨이퍼를 고온의 반응로 내로 이송시켜 상기 반응로 내의 산소를 이용하여 상기 웨이퍼 표면에 산화막을 형성하는 확산 장치에 있어서,상기 반응로(10)의 입구측에 개스 공급 노즐(20)을 구비하여, 웨이퍼가 탑재된 보트(9)를 반응로(10) 내로 이송하거나 또는 인출시킬 때, 상기 개스 공급 노즐(20)을 통해 불활성 개스를 공급하여 대기중의 산소가 고온의 웨이퍼 표면과 결합, 자연 산화막을 형성하는 것을 방지할 수 있게 한 것을 특징으로 하는 반도체 제조 공정용 확산 장치.
- 제 1 항에 있어서, 상기 개스 공급 노즐(20)은 개스 유입구(21)측으로부터 출구(22)측으로 갈수록 단면적이 확산되는 형태로 이루어진 것을 특징으로 하는 반도체 제조 공정용 확산 장치.
