Patent ID: 7012003

Claim:
A method for producing a memory component comprising a memory cell region having memory cells and first control electrode tracks for driving individual memory cells and a peripheral region having peripheral elements and second control electrode tracks for driving the peripheral elements, comprising: applying, in a first direction, to a provision of a substrate having memory cell structures, an insulation layer, a layer stack and a patterning layer; applying a first mask layer on the patterning layer in the first direction; patterning the first mask layer in the first direction, the first mask layer comprising, in the memory cell region and the peripheral region, closed regions, in which the first mask layer is not removed and which are assigned to the first and second control electrode tracks, and open regions, in which the first mask layer is removed, in at least one second direction perpendicular to the first direction; transferring the mask structure of the first mask layer to the patterning layer in the first direction, such that the structure of the patterning layer corresponds to the mask structure; removing the first mask layer; filling open regions of the patterning layer in at least the memory cell region with a protective material, such that the open regions are filled with the protective material in the second direction in a manner essentially flush with the patterning layer; selectively setting the expansion of closed regions of the patterning layer in the peripheral region in at least the second direction, such that the expansion of closed regions bounded by at least one open region of the patterning layer, the open region having no protective material, is set; removing the protective material in the memory cell region and in the peripheral region selectively with respect to the patterning layer and the layer stack; transferring the structures of the patterning layer in the first direction to the layer stack to produce the first and the second control electrode tracks.
