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.
