METHOD FOR PHOTOLITHOGRAPHIC STRUCTURING BY MEANS OF A CARBON HARD MASK LAYER WHICH HAS A DIAMOND-LIKE HARDNESS AND IS PRODUCED BY MEANS OF A PLASMA-ENHANCED DEPOSITION METHOD

摘要

According to the invention, a carbon hard mask layer (2) is applied to a substrate to be structured (1) by means of a plasma-enhanced deposition method in such a way that it has a diamond-like hardness in at least one vertical section of a layer. During the production of said diamond-type vertical section of a layer, the deposition parameters are adjusted in such a way that certain diamond-type growth regions are removed in situ by means of subsequent etching processes, and other diamond-type regions remain.
