The invention discloses a power matching apparatus used in semiconductor equipment. The apparatus comprises: a sensor and a matching network, wherein the sensor is connected with a power source of the semiconductor equipment and is used to collect signals of the power source and acquire an impedance adjustment amount; the matching network is connected with the sensor and is used to adjust an output impedance of the matching network so as to match with an input impedance of a reaction chamber of the semiconductor equipment according to the impedance adjustment amount from the sensor and is also used to filter a signal whose frequency is different from the frequency of the signal of the power source. Therefore, a power supply used by a top electrode and a lower electrode and the power matching apparatus work normally and a matching scope of the power matching apparatus can not be influenced. The invention further discloses the semiconductor equipment.
