发明名称 Method for fabricating a self-aligning mask
摘要 A description is given of a method for a selective masking of a structure with a small structure surface with respect to a structure with a larger structure surface. To that end, the structures are filled with a covering layer. The covering layer is formed with a larger thickness above the first structure, which has the larger structure surface, than above the second structure. Afterward, the covering layer is removed by a homogeneous removal method, so that first the structure surface of the second structure is uncovered. A simple self-aligning method for fabricating a mask for uncovering the second structure is thus provided.
