Classification: CPC C  G | IPC C  G

Claim 1:
2. A control method of a plating apparatus that supplies a current from a rectifier to a substrate to plate the substrate, the control method of the plating apparatus comprising:
a step of outputting, from the rectifier, a current with a first current value, in a state where the substrate and a substrate holder holding the substrate are not electrically connected to the rectifier;
a step of acquiring an output voltage value of the rectifier;
a step of comparing the output voltage value with a predetermined reference voltage value;
a step of determining that a short circuit does not occur in a circuit for connecting the rectifier and the substrate, in a case where the output voltage value is higher than the reference voltage value;
a step of determining that the short circuit occurs in the circuit for connecting the rectifier and the substrate, in a case where the output voltage value is lower than the reference voltage value;
a step of electrically connecting the substrate and the substrate holder holding the substrate to the rectifier, and performing plating processing of the substrate, in response to the determination that the short circuit does not occur in the circuit for connecting the rectifier and the substrate, wherein the plating processing of the substrate is performed by outputting a current with a second current value from the rectifier, and wherein the first current value is smaller than the second current value; and
a step of prohibiting the plating processing of the substrate, in response to the determination that the short circuit occurs in the circuit for connecting the rectifier and the substrate.
