    摘要： 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.

    摘要： The present invention provides a plating apparatus which uses an insoluble anode and which can perform plating of a substrate stably while preventing oxygen gas, generated due to the use of the insoluble anode, from causing defects in the substrate. The plating apparatus includes: a substrate holder for holding a substrate; a cathode section including a seal ring for contacting a peripheral portion of a surface, to be plated, of the substrate held by the substrate holder to seal the peripheral portion water-tightly, and a cathode for contacting the substrate to supply current to the substrate; a vertically-movable electrode head provided above the cathode section, including an anode chamber housing an anode made of an insoluble material and having a bottom opening closed with a water-permeable porous member; a plating solution injection section for injecting a plating solution between the anode and the surface, to be plated, of the substrate held by the substrate holder; a power source for applying a plating voltage between the cathode and the anode; and a gas discharge line for discharging a gas from the anode chamber.
