본 발명은 반도체장치의 제조공정에 사용되는 스퍼터(sputter)장치의 냉각설비에 관해 개시한다. 본 발명에 의한 반도체장치의 제조공정에 사용되는 스퍼터(sputter)장치의 냉각설비에는 메인 플로우 미터와 상기 메인 플로우 미터의 청소, 교체 또는 고장시 상기 메인 플로우 미터가 직렬로 연결되어 있는 제1 냉각관으로부터 냉각수의 흐름을 우회시킬 수 있는 제2 냉각관이 마련되어 있고 상기 제2 냉각관에는 계속적으로 냉각수의 흐름의 이상 상태를 감지할 수 있는 보조 플로우 미터가 구비되어 있다. 결국 상기 메인 플로우 미터와 상기 보조 플로우 미터는 병렬로 상기 제1 냉각관에 연결되어 있다. 따라서 상기 어느 한 플로우 미터에 장애가 있더라도 스퍼터 장치의 계속적인 냉각을 실시할 수 있으므로 스퍼터장치를 이용하는 반도체장치의 생산을 계속 할 수 있으므로 반도체장치의 생산성이 높아지고 따라서 단위 제품의 단가를 낮출 수 있어서 경쟁력도 높일 수 있는 잇점이 있다.
Abstract:
PURPOSE: A system for detecting a wafer deposition layer by a dual sensor is provided to determine whether a metal layer is deposited on a wafer while operating a physical deposition apparatus by detecting and comparing the difference of reflectivity. CONSTITUTION: An input reflectivity detecting unit(20) detects the reflectivity on the wafer(12) supplied to a chamber(10). An output reflectivity detecting unit(30) detects the reflectivity on the wafer taken out from the chamber after a metal layer deposition process is completed in the chamber. A reflectivity comparing unit(40) receives and compares the input reflectivity and output reflectivity transmitted from the input reflectivity detecting unit and the output reflectivity detecting unit and determines whether the metal layer is deposited on the wafer.
