Abstract:
1. A nano-imprint device comprising at least: a substrate, having a surface, on the substrate, a plurality of nano-trenches parallel two by two, each nano-trench extending in a longitudinal direction and being delimited in a lateral direction by side walls, the nano-trenches and the side walls being directed substantially perpendicular to said surface of the substrate, each nano-trench comprising a bottom surface, in a cross-sectional view along the longitudinal direction, the bottom surface of each nano-trench has at least one first and one second level in a direction perpendicular to the substrate, respectively of depth h in a cross-sectional view along the lateral direction, the bottom surface of each nano-trench has only one level that is at the depth h the bottom surfaces of the nano-trenches, of the least deep level h
