Abstract
Uniformity in plated film thickness in a plating apparatus is improved. A plating apparatus for plating a substrate by making electric current flow from an anode to the substrate is provided. The plating apparatus comprises: plural anode-side electric wires which are electrically connected to the anode via plural electric contacts on the anode; plural substrate-side electric wires which are electrically connected to the substrate via plural electric contacts on the substrate; plural variable resistors positioned, in at least one of the anode side and the substrate side, in middle positions in the plural anode-side electric wires or the plural substrate-side electric wires; and a controller constructed to adjust each of resistance values of the plural variable resistors.
