  • Patent number: 10896810
    Abstract: To provide a RF generating apparatus that enables apparatus size to be decreased and the cost reduced thereby while also improving power efficiency by performing a stable matching operation, and to provide a plasma treatment apparatus using said apparatus. This RF generating apparatus comprises a plurality of RF generators and matching units, the matching units being provided with only variable-capacity capacitors connected in parallel, thereby reducing the number of elements in terms of the variable-capacity capacitors. A matching calculation section for the RF generators determines, on the basis of traveling waves and reflection waves detected by a detection circuit, the capacity values of the variable-capacity capacitors for the matching units, while adjusting and determining the oscillation frequencies for oscillation circuits in the RF generators so as to decrease the level of the reflection waves. The plasma treatment apparatus uses this RF generating apparatus.
