摘要： A cathode potential is applied to a conductive layer formed on a substrate having a depression pattern. A plating solution in electrical contact with an anode is supplied to the conductive layer to form a plating film on the conductive layer. At this time, the plating solution is supplied by causing an impregnated member containing the plating solution to face the conductive layer. Since the plating solution stays in the depression, a larger amount of plating solution is supplied than on the upper surface of the substrate, and the plating rate of the plating film in the depression increases. Consequently, the plating film can be preferentially formed in the depression such as a groove or hole.

摘要： In order to regulate the metal ion concentration in an electrolyte fluid serving to electrolytically deposit metal and additionally containing substances of an electrochemically reversible redox system, it has been known in the art to conduct at least one portion of the electrolyte fluid through one auxiliary cell provided with one insoluble auxiliary anode and at least one auxiliary cathode, a current being conducted between them by applying a voltage. Accordingly, excess quantities of the oxidized substances of the redox system are reduced at the auxiliary cathode, the formation of ions of the metal to be deposited being reduced as a result thereof. Starting from this prior art, the present invention relates to using pieces of the metal to be deposited as an auxiliary cathode.

摘要： A method for on-line removal of cathode depositions during electrochemical process. The process control means (30) are arranged to alternate the unipolar machining voltage pulses U1 with the voltage pulses of opposite polarity U2 to the work piece (2) and the cathode (3). The process control means comprise an arrangement to determine the amount of cathode depositions on-line based on the operational parameter. Only in case the operational parameter exceeds the allowable level, the process control means (30) alternate the unipolar machining voltage pulses U1 with the voltage pulses of opposite polarity U2. In this case the cathode wear is minimized.
