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 2):
The impedance matching system according to  claim 1 , wherein:\n an adjustable load is provided by the load circuit; and the control unit comprises:\n a switch control module, configured to control, according to the preset time sequence, the switch to enable the RF power supply to be connected to the reaction chamber or enable the RF power supply to be connected to the load circuit; and \n a load control module, configured to adjust an impedance of the adjustable load to be a preset impedance when the switch connects the RF power supply to the load circuit, the preset impedance being an input impedance of the reaction chamber at an ending time point of a previous connection between the RF power supply and the reaction chamber.
