    • PROBLEM TO BE SOLVED: To provide an atmospheric-pressure plasma generating apparatus in which uniform line plasma is generated using a long waveguide and uniform processing can be performed to a workpiece.SOLUTION: A plasma generating apparatus 20 includes: a microwave generating apparatus 21 generating microwaves; a rectangular waveguide 22 connected to the microwave generating apparatus 21 and provided with an antenna section 40 as a part of the rectangular waveguide; a gas supply apparatus 23 connected to the rectangular waveguide 22 and supplying processing gas to an inside of the rectangular waveguide; an exhaust apparatus 24 for exhausting the gas in the antenna section 40 and, if necessary, exhausting an inside of a processing container 10; and a phase shift apparatus 25A changing the phase of a standing wave in the rectangular waveguide 22. The antenna section 40 has a slot hole 41, and the processing gas having been supplied to the inside of the rectangular waveguide 22 in an atmospheric pressure state is transformed into plasma using microwaves and is discharged through the slot hole 41 toward an external workpiece.
    • 要解决的问题:提供一种使用长波导产生均匀的线等离子体并且可以对工件进行均匀处理的大气压等离子体产生装置。 解决方案:等离子体产生装置20包括:产生微波的微波产生装置21; 连接到微波发生装置21的矩形波导22,并且设置有作为矩形波导的一部分的天线部分40; 连接到矩形波导22并将处理气体提供给矩形波导的内部的气体供应装置23; 用于排出天线部40中的气体的排气装置24,如果需要,排出处理容器10的内部; 以及改变矩形波导22中的驻波相位的相移装置25A。天线部40具有槽孔41,并且在大气压状态下被供给到矩形波导管22的内部的处理气体为 使用微波转化成等离子体,并通过槽孔41朝向外部工件排出。 版权所有(C)2013,JPO&INPIT
