An electrolytic processing apparatus can planarize uniformly over an entire surface of a substrate under a low pressure without any damages to the substrate. The electrolytic processing apparatus has a substrate holder configured to hold and rotate a substrate having a metal film formed on a surface of the substrate and an electrolytic processing unit configured to perform an electrolytic process on the substrate held by the substrate holder. The electrolytic processing unit has a rotatable processing electrode, a polishing pad attached to the rotatable processing electrode, and a pressing mechanism configured to press the polishing pad against the substrate. The electrolytic processing unit also has a liquid supply mechanism configured to supply an electrolytic processing liquid between the substrate and the rotatable processing electrode, a relative movement mechanism operable to move the substrate and the rotatable processing electrode relative to each other, and a power supply configured to applying a voltage between the rotatable processing electrode and the metal film of the substrate so that the rotatable processing electrode serves as a cathode and the metal film of the substrate serves as an anode. |
