Assignee: EBARA CORPORATION
Field: Surface technology, coating (Chemistry)
Classification: CPC C  G | IPC C  G

Claim 2:
3. A plating apparatus comprising:
a plating device for plating a substrate;
a rectifier for supplying a current to the substrate; and
a control unit, the control unit being configured to
cause the rectifier to output 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,
acquire an output voltage value of the rectifier,
compare the output voltage value with a predetermined reference voltage value, and
determine that a short circuit occurs in a circuit for connecting the rectifier and the substrate, in a case where the output voltage value is lower than the reference voltage value,

wherein the rectifier is configured to output a current with a second current value to plate the substrate, wherein the first current value is smaller than the second current value.
