    Abstract: The invention includes a semiconductive processing method of electrochemical-mechanical removing at least some of a conductive material from over a surface of a semiconductor substrate. A cathode is provided at a first location of the wafer, and an anode is provided at a second location of the wafer. The conductive material is polished with the polishing pad polishing surface. The polishing occurs at a region of the conductive material and not at another region. The region where the polishing occurs is defined as a polishing operation location. The polishing operation location is displaced across the surface of the substrate from said second location of the substrate toward said first location of the substrate. The polishing operation location is not displaced from said first location toward said second location when the polishing operation location is between the first and second locations. The invention also includes a semiconductor processing method of removing at least some of a conductive material from over a surface of a semiconductive material wafer. A polishing pad is displaced across an upper surface of the wafer from a central region of the wafer toward a periphery of the wafer, and is not displaced from the periphery to the central region.

    Abstract: Semiconductor wafers for the production of electronic components must have a surface as perfect as possible for subsequent processes. For that purpose a flat n-Si body is electrolytically polished in a fluoride-containing electrolyte solution to which is applied an anodic potential while the surface to be treated is irradiated with light whose energy is at least equal to that of the band gap, or a flat p-Si body is similarly treated in a dark environment. At the same time, an electroanalytic monitoring process is carried out to detect the occurrence of a periodic current oscillation. The surface is polished during a few such current oscillations. The treatment comprises in particular the anodic oxidation and electrochemical etching of the surface, if required also an electric polishing process, and allows a high electronic quality characterised by the interface state density to be obtained by immediate hydrogen termination during the transient dark current that sets in.
