METHOD FOR PRODUCING A TOOL WHICH CAN BE USED TO CREATE SURFACE STRUCTURES IN THE SUB- mu M RANGE

摘要

The invention relates to a method for producing a tool, and a tool which can be used to create optically active surface structures in the sub- mu m range. Said tool comprises a support surface to which surface structures are applied by depositing material, said surface structures being raised in relation to the support surface. The invention is characterised in that the support surface is indirectly bonded with a mask (2) in which openings (3) having diameters in the sub- mu m range are provided or can be placed; the support surface and the mask are subjected to a coating process during which coating material is deposited onto the support surface via the openings (3) in the mask; the mask is removed from the support surface when a partial amount of the average height of the end structure pertaining to the surface structures is obtained; and the coating process is continued without a mask and with similar or different coating material.
