Claims (8)
- 기판(w)에 박막을 증착하는 챔버(10)와, 상기 챔버(10)로 반응원 또는 퍼지가스를 공급하기 위한 가스정글(20)과, 상기 챔버(10)와 가스정글(20)의 반응가스 또는 퍼지가스를 외부로 배기시키는 배기펌프(30)를 포함하는 박막증착장치를 이용하여,상기 챔버(10) 내부로 제1반응원을 피딩하는 제1피딩단계(S10)와, 상기 제1반응원을 상기 챔버(10)로부터 퍼지하는 제1퍼지단계(S20)와, 상기 챔버(10)로 제2반응원을 피딩하는 제2피딩단계(S30)와, 상기 챔버(10)로부터 제1반응원과 반응하지 않거나 반응하여 생성된 부산물을 퍼지하는 제2퍼지단계(S40)로 구성되는 싸이클을 반복함으로써 상기 기판(w) 상에 박막을 증착하는 ALD 박막증착방법에 있어서,한 싸이클과 다음 싸이클 사이에서 수행되는 것으로서, 상기 제1반응원 및 제2반응원의 공급없이 상기 챔버(10) 내부의 압력을 높이거나 낮추는 프리압력변화단계(pre-pressure change step)(S50)(S50')를 포함하는 것을 특징으로 하는 ALD 박막증착방법.
- 제1항에 있어서,상기 기판(w) 상에 형성되는 박막이 우수한 스텝커버리지를 가지도록 할 경우,상기 프리압력변화단계(S50)는 상기 챔버(10) 내부의 압력을 피딩 및 퍼지가 수행되는 공정압력보다 낮추는 것을 특징으로 하는 ALD 박막증착방법.
- 제2항에 있어서,상기 프리압력변화단계(S50)는, 상기 챔버(10)와 가스정글(20) 사이에 연결되는 밸브를 닫고 상기 배기펌프(30)의 펌핑을 통하여 수행되는 것을 특징으로 하는 ALD 박막증착방법.
- 제2항에 있어서,상기 프리압력변화단계(S50)에서는, 상기 챔버(10)의 압력을 상기 제1피딩단계(S1) 시의 공정압력보다 20% 이상 낮추는 것을 특징으로 하는 ALD 박막증착방법.
- 제1항에 있어서,상기 기판(w) 상에 형성되는 박막이 나쁜 스텝커버리지를 가지도록 할 경우,상기 프리압력변화단계(S50')는, 상기 챔버(10) 내부의 압력을 피딩 및 퍼지가 수행되는 공정압력보다 높이는 것을 특징으로 하는 ALD 박막증착방법.
- 제5항에 있어서,상기 프리압력변화단계(S50')는, 상기 챔버(10)로 별도의 불활성가스를 공급함으로써 수행되는 것을 특징으로 하는 ALD 박막증착방법.
- 제6항에 있어서,상기 프리압력변화단계(S50')에서 공급되는 불활성가스는, 상기 챔버(10)와 가스정글(20) 사이에 별도의 가스라인(40)을 구성한 후 그 가스라인(40)을 통하여 공급될 수도 있고, 상기 챔버(10)와 가스정글(20) 사이를 연결하는 제1,2가스라인을 통하여 공급될 수도 있는 것을 특징으로 하는 ALD 박막증착방법.
- 제6항에 있어서, 상기 프리압력변화단계(S50')에서는, 상기 챔버(10)의 압력을 상기 제1피딩단계(S10) 시의 공정압력보다 20% 이상 높이는 것을 특징으로 하는 ALD 박막증착방법.
