发明名称 Coaxial type impedance matching device and impedance detecting method for plasma generation
摘要 A plasma generating method generates plasma in a treating chamber by controlling a high-frequency generating unit to generate a high-frequency signal and by feeding the high-frequency signal to the treating chamber through an impedance matching device. The plasma generating method includes controlling the impedance matching device, when the plasma is generated in the treating chamber, so as to satisfy a preset matching condition, and then controlling the high-frequency generating unit to generate and feed the high-frequency signal of the power generating the plasma, to the treating chamber.
