    • A substrate processing apparatus cleaning method that includes: containing a cleaning gas in a reaction tube without generating a gas flow of the cleaning gas in the reaction tube by supplying the cleaning gas into the reaction tube and by completely stopping exhaustion of the cleaning gas from the reaction tube or by exhausting the cleaning gas at an exhausting rate which substantially does not affect uniform diffusion of the cleaning gas in the reaction tube from at a point of time of a period from a predetermined point of time before the cleaning gas is supplied into the reaction tube to a point of time when several seconds are elapsed after starting of supply of the cleaning gas into the reaction tube; and thereafter exhausting the cleaning gas from the reaction tube.
    • 一种基板处理装置的清洗方法,其特征在于,包括:在反应管内容纳清洗气体,在反应管内不产生清洗气体的气流,将清洗气体供给反应管, 反应管或通过以排气速率排出清洁气体,其排气速率基本上不影响清洁气体在反应管中的均匀扩散从在清洁气体被供给到预定时间之前的预定时间点的时间点 反应管到开始向反应管供给清洁气体后经过几秒钟的时间点; 然后从反应管中排出清洗气体。
