Microstructure for producing light-diffracting microstructures is formed by overlapping a first relief structure with a second structure

摘要

Microstructure is formed by overlapping a first relief structure with a second structure. The first relief structure is a structure mechanically formed in a layer (2) and the second relief structure is a diffraction structure (12) having recesses which are photochemically produced on the surface of the first relief structure. An independent claim is also included for a process for producing a light-diffracting microstructures (13).
