Electroplating apparatus
Abstract:
An electroplating apparatus has a cathode base for supporting a substrate, and a clamper for clamping a peripheral edge portion of the substrate against the cathode base. A plating solution is supplied onto the substrate so that the surface of the substrate is plated. A negative pressure source clamps the substrate by drawing the clamper under a negative pressure through a suction conduit.
