  • Patent number: 8293431
    Abstract: A lithographic mask comprises a first layer including grooves, a second layer including regions, sections and a groove-like structure that encloses the sections. The first and second layers are formed so as to reduce electrical potential differences within the second layer. A method of forming a lithographic mask includes forming first and second layers to dispose the second layer over the first layer, patterning the second layer to comprise sections, a region, and a groove-like structure enclosing the sections, and forming grooves in the first layer at portions not covered by the second layer. The first and second layers are formed to reduce potential differences within the second layers during the step of forming the grooves in the first layer.

  • Patent number: 8003538
    Abstract: The present invention relates to a method for producing a structure serving as an etching mask on the surface of a substrate. In this case, a first method involves forming a first partial structure on the surface of the substrate, which has structure elements that are arranged regularly and are spaced apart essentially identically. A second method involves forming spacers on the surface of the substrate, which adjoin sidewalls of the structure elements of the first partial structure, cutouts being provided between the spacers. A third method step involves introducing filling material into the cutouts between the spacers, a surface of the spacers being uncovered. A fourth method step involves removing the spacers in order to form a second partial structure having the filling material and having structure elements that are arranged regularly and are spaced apart essentially identically. The structure to be produced is composed of the first partial structure and the second partial structure.
