Abstract:
An impedance matching system is provided. The impedance matching system includes: an impedance matching device arranged between a radio frequency (RF) power supply and a reaction chamber, adapted to connect the RF power supply to the reaction chamber through a switch, and configured to automatically perform an impedance matching on an output impedance of the RF power supply and an input impedance of the impedance matching device; the switch and a load circuit, the switch being configured to enable the RF power supply to be selectively connected to the reaction chamber or to the load circuit; and a control unit configured to control the switch to connect the RF power supply to the reaction chamber or connect the RF power supply to the load circuit according to a preset timing sequence. The impedance matching device is configured to convert a continuous wave output of the RF power supply into a pulse output according to the preset timing sequence, and provide the pulse output to the reaction chamber. The preset timing sequence is obtained based on a frequency and a duty cycle of a pulsed RF signal required by a process.

Claim (Index 10):
The impedance matching system according to  claim 9 , wherein:\n a target capacitance of the adjustable capacitor is calculated by the control unit based on reflected power transmitted from the detection unit, and the capacitance of the adjustable capacitor is adjusted to the target capacitance.
