摘要： PROBLEM TO BE SOLVED: To solve a problem of a conventional high frequency device varying an output frequency of a high frequency electric power to control lowering of the reflection coefficient absolute value Γ, capable of adjusting a reactance component X of a load-side impedance ZL, while incapable of adjusting resistance component R, sometimes thereby incapable of lowering the reflection coefficient absolute value Γ. SOLUTION: The high frequency device supplies an electric power to a plasma processing apparatus, for example. In the high frequency device, a frequency control circuit 11 varies the output frequency of the high frequency electric power to control lowering of the reflection coefficient absolute value Γ. When the control cannot lower the reflection coefficient absolute value Γ than a reference value, a reactance element control circuit 19 varies a variable capacitor VC1 in an impedance regulator 3 to control lowering of the reflection coefficient absolute value Γ. This lowers the reflection coefficient absolute value Γ than ever before. Moreover, use of a variable capacitor VC2 provides the further adjustment. COPYRIGHT: (C)2008,JPO&INPIT
