    Abstract: A method, apparatus and anode for plating copper or other metals onto a barrier or seed layer of a wafer surface is described. A copper layer of uniform thickness is plated on the surface by, for instance, maintaining a constant current density between the anode and wafer surface. Several configurations of anodes are described for obtaining the constant current density.

    Abstract: The present invention is directed to a method and apparatus for plating a surface of a semiconductor workpiece (wafer, flat panel, magnetic films, etc.) using a liquid conductor that makes contact with the outer surface of the workpiece. The liquid conductor is stored in a reservoir and pump through an inlet channel to the liquid chamber. The liquid conductor is injected into a liquid chamber such that the liquid conductor makes contact with the outer surface of the workpiece. An inflatable tube is also provided to prevent the liquid conductor from reaching the back face of the workpiece. A plating solution can be applied to the front face of the workpiece where a retaining ring/seal further prevents the plating solution and the liquid conductor from making contact with each other. In an alternative embodiment, electrical contacts may be formed using an inflatable tube that has either been coated with a conductive material or contains a conductive object. The inflatable tube further provides uniform contact and pressure along the periphery of the workpiece, which may not necessarily be perfectly flat, because the tube can conform according to the shape of the periphery of the workpiece. Further, the present invention can be used to dissolve/etch a metal layer from the periphery of the workpiece.

    Abstract: The present cup-type plating apparatus improves a conventional cup-type plating apparatus and prevents the surface of a wafer due to a mist of the plating solutions from being contaminated. A plating solution is supplied to a wafer which is placed on a wafer support provided along an opening at the top of a plating tank from a solution-supply port provided at the bottom of the plating tank by an upward-moving stream; the plating solution is made to flow out of a solution-outlet port provided for the plating tank; and plating is performed while the plating solution is brought into contact with a surface of the placed wafer, which is to be plated, wherein the solution-outlet port has a solution-outlet path in which the discharged plating solution is isolated from the outer space.

    Abstract: The present invention provides a method and apparatus that plates/deposits a conductive material on a semiconductor substrate and then polishes the same substrate. This is achieved by providing multiple chambers in a single apparatus, where one chamber can be used for plating/depositing the conductive material and another chamber can be used for polishing the semiconductor substrate. The plating/depositing process can be performed using brush plating or electro chemical mechanical deposition and the polishing process can be performed using electropolishing or chemical mechanical polishing. The present invention further provides a method and apparatus for intermittently applying the conductive material to the semiconductor substrate and also intermittently polishing the substrate when such conductive material is not being applied to the substrate. Furthermore, the present invention provides a method and apparatus that plates/deposits and/or polishes a conductive material and improves the electrolyte mass transfer properties on a substrate using a novel anode assembly.

The method includes depositing a conductive seed layer on a production surface of the substrate, and depositing a backside conductive layer on a portion of the non-production side of the substrate, the backside conductive layer extending around a bevel of the substrate to electrically communicate with the seed layer. The method further includes securing the substrate in a chuck configured to engage the non-production surface of the substrate, contacting the backside conductive layer with an electrical cathode contact on the non-production side of the substrate, and plating over the conductive seed layer via application of an electrolyte to the production surface of the substrate and applying an electrical bias to the electrical cathode contact and an anode in communication with the electrolyte.

    Abstract: In a process for producing a semiconductor member, and a solar cell, making use of a thin-film crystal semiconductor layer, the process comprises the steps of: (1) anodizing the surface of a first substrate to form a porous layer at least on one side of the substrate, (2) forming a semiconductor layer at least on the-surface of the porous layer, (3) removing the semiconductor layer at its peripheral region, (4) bonding a second substrate to the surface of the semiconductor layer, (5) separating the semiconductor layer from the first substrate at the part of the porous layer, and (6) treating the surface of the first substrate after separation and repeating the above steps (1) to (5). This process enables separation of the thin-film semiconductor layer at a small force while causing less cracks, breaks or defects to be brought into it and can manufacture high-performance semiconductor members and solar cells in a good efficiency.
