Abstract
A method for producing a semiconductor structure includes applying at least one first layer, etching the first layer using a masking layer such that fences are produced, and, after removal of the masking layer and application of an auxiliary layer, the auxiliary layer and the fences are removed jointly except for a predetermined extent of the auxiliary layer. The present invention also relates to use of the method for producing spacers in a semiconductor structure.
