Abstract:
1. A holding device for fixing a semiconductor wafer in a plasma etching device, comprising: a holding arrangement that is positioned on a substrate electrode and on which a substrate of the semiconductor wafer is electrostatically fixable; a clamping arrangement; and a load body that is positioned on the substrate electrode and presses the holding arrangement onto the substrate electrode, the load body being connected with a base that supports the substrate electrode via the clamping arrangement, which presses the load body onto the substrate electrode, the load body and the base being electrically insulated from the substrate electrode; wherein the clamping arrangement includes a metallic clamping ring, which is electroconductively connected to the base via at least one of a metallic fastening element and a metallic connecting element; and wherein the base is grounded.
