Claims (5)
- 식각 대상 물질이 내장된 챔버에 식각액을 안내하기 위한 식각액 안내배관을 구비한 반도체 제조장비에 있어서, 액화질소를 저장하는 액화질소 탱크와, 상기 액화 질소 탱크로부터의 액화질소를 상기 식각액 안내배관에 의해 안내되는 식각액과 혼합하는 수단과, 상기 혼합된 식각액 및 액화질소의 압력을 낮추어서 액화질소를 기화시킴과 아울러 식각액을 냉각시키는 압력변화수단을 구비한 것을 특징으로 하는 식각액 열 교환장치.
- 제1항에 있어서, 상기 압력변화수단은 상기 챔버와 상기 혼합수단의 사이에 설치되어 공동영역을 형성하는 공동부를 구비한 것을 특징으로 하는 식각액 열 교환장치.
- 제2항에 있어서, 상기 혼합수단과 상기 공동부 사이에 설치되어 공동부에서의 액화질소의 기화를 촉진시키는 기화촉진수단을 추가로 구비한 것을 특징으로 하는 식각액 열 교환장치.
- 제3항에 있어서, 상기 기화촉진수단은 상기 혼합수단으로부터 상기 공동부쪽으로 유입될 상기 식각액 및 액화질소를 분출시키는 노즐을 구비한 것을 특징으로 하는 식각액 열 교환장치.
- 제2항 내지 제4항 중 어느 한 항에 있어서, 상기 공동부의 저면으로부터 수직으로 일정 높이까지 신장되어 일정량의 식각액이 저장된 후 유동되도록 하는 중간막을 추가로 구비한 것을 특징으로 하는 식각액 열 교환장치.
