Patent ID: 8586142

Claim:
A method for producing nanopatterns or micropatterns comprising: depositing a mask on a surface of a substrate; disposing the substrate in a chamber; introducing an inert gas and a source material into the chamber such that the inert gas and the vaporized source material are present in the chamber at the same time, evaporating the source material under such evaporation condition performed at such pressure to scatter atoms of the source material by collision with the inert gas and to form a layer onto both a shadowed surface area and a non-shadowed surface area of the mask and the substrate, wherein the non-shadowed surface area is an area on the substrate and the mask in the deposition process having a direct line of sight with the source of evaporation, the shadowed surface area is an area on the substrate and the mask in the deposition process, which does not have a direct line of sight with the source of evaporation, and the pressure is on or above 1×10 −5 hPa and below 1×10 −3 hPa.
