    • PURPOSE: To provide a treatment apparatus and treatment method capable of shortening the time for switching gaseous raw materials by shortening the time required for evacuation of the gaseous raw materials and of maintaining the temperature on a substrate surface under treatment constant. CONSTITUTION: The treating gases containing gaseous raw materials(TiCl4 and NH3) and inert gas(N2) are supplied into a treating vessel 2. The pressure in the treating vessel 2 is detected by a pressure gage 6 and the flow rate of the treating gases supplied into the treating vessel 2 is controlled in accordance with the result of the detection. Purging of the gaseous raw materials is performed by the inert gas. The flow rate as the entire part of the gaseous raw materials is controlled and the pressure in the treating vessel 2 is maintained constant by maintaining the flow rate of the treating gaseous raw material constant and by controlling the flow rate of the inert gas.
    • 目的:提供一种处理装置和处理方法,其能够缩短气态原料的切换时间,缩短气体原料抽真空所需的时间,并将处理温度保持在处理常数上。 构成:将含有气态原料(TiCl 4和NH 3)和惰性气体(N 2)的处理气体供给到处理容器2.处理容器2中的压力由压力计6检测,处理气体的流量 根据检测结果来控制供应到处理容器2中。 气态原料的清除是通过惰性气体进行的。 通过保持处理气态原料的流量恒定并控制惰性气体的流量,控制作为气态原料的整个部分的流量,并且处理容器2中的压力保持恒定。
