Description
Claims (5)
- 웨이퍼 건조공정에서 휘발성이 강한 소수성 유기용매를 증기상이나 액상으로 첨가함으로써 세정액 표면에 공기/소수성 유기용매/알콜(Alcohol)/물(water)의 계면이 형성되도록 하여 수행함을 특징으로 하는 웨이퍼 건조 방법.
- 제1항에 있어서, 상기 소수성 유기용매는 저분자량의 탄화수소(Hydrocarbon)류, 카본플로리드(Carbonfloride)류, 그리고 기타 용매를 포함하며, 물에 녹지 않고 표면에 부유하는 특성을 가지는 유기용매임을 특징으로 하는 웨이퍼 건조 방법.
- 제1항에 있어서, 상기 알콜류는 Maragoni 건조 방법에 사용되는 유기용매(Organic liquid)임을 특징으로 하는 웨이퍼 건조 방법.
- 제1항에 있어서, 친수성의 웨이퍼 표면을 적시지 않으므로 액표면에 존재하는 입자들이 웨이퍼를 액속에서 인출시 웨이퍼 표면으로 재오염되는 것을 효과적으로 방지할 수 있도록 소수성의 유기용매를 세정액 표면에 부유시켜 줌을 특징으로 하는 웨이퍼 건조 방법.
- 제1항에 있어서, 휘발성이 큰 유기용매를 세정액 표면에 부유시켜 웨이퍼 표면의 잔류 알콜/물의 증기압을 상승시키게 되어 보다 잘 제거될 수 있게 하므로 친수성의 웨이퍼 표면을 보다 깨끗하게 건조 시키도록 함을 특징으로 하는 웨이퍼 건조 방법.
