    • Provided is a substrate processing apparatus which is capable of detecting malfunction of mechanisms installed inside MFC. An inert gas supply line (308) for supplying an inert gas, a first shut-off valve (300) for shutting off the supply of the inert gas, a process gas supply line (310) for supplying a process gas, and a second shut-off valve (302) for shutting off the supply of the process gas are installed at the upstream side of the MFC (241). A gas supply pipe (232) connected to a process chamber (210), a third shut-off valve (304) for shutting off the supply of gas to the gas supply pipe (232), an exhaust vent line (318) which is exhaustible, a fourth shut-off valve (306) for shutting off the supply of gas to the exhaust vent line (318) are installed at the downstream side of the MFC (241). A main control unit (239) determines that the MFC (241) is abnormal if a transition time exceeds a previously set time when the MFC (241) transits from a close state to an open state while the shut-off valves are in a close state.
    • 提供了能够检测安装在MFC内部的机构的故障的基板处理装置。 用于供应惰性气体的惰性气体供应管线(308),用于切断惰性气体供应的第一截止阀(300),用于供给处理气体的处理气体供应管线(310)和第二 用于切断处理气体供给的切断阀(302)安装在MFC(241)的上游侧。 连接到处理室(210)的气体供给管(232),用于切断向气体供给管(232)供给气体的第三切断阀(304),排气排气管线(318) 在所述MFC(241)的下游侧安装有用于切断向所述排气导管(318)供给气体的第四截止阀(306)。 如果当MFC(241)从关闭状态转换到打开状态而转换时间超过预先设定的时间时,主控制单元(239)确定MFC(241)异常,而截止阀处于闭合状态 州。
