Patent attributes
Provided are an RF power distribution device and an RF power distribution method. The RF power distribution device includes an impedance matching network for transferring power from an RF power source and a power distribution unit for distributing the output power from the impedance matching network to at least one electrode generating capacitively-coupled plasma. The power distribution unit includes a first reactive element connected in series to a first electrode, a variable capacitor having one end connected in parallel to the first reactive element and the first electrode and the other end grounded, and a second reactive element having one end connected to a first node where the one end of the variable capacitor and one end of the first reactance device are in contact with each other and the other end connected to a second node where a second electrode and an output terminal of the impedance matching network are connected.
