Abstract

A fabrication method in thin layers, for example of integrated electronic circuits or MEMS. A correction method allows design errors made for example by photolithography in a thin layer to be repaired, and without necessarily having to utilize a new mask or without having to correct an erroneous mask. A lithography device allows certain of operations of such a method to be employed.
