The Applied Microstructures MVD 100 system deposits molecular films on surfaces. These films serve a wide range of purposes ranging from antistiction coatings of nanoimprint lithography stamps to protecting MEMS structures. They are created as self-assembled monolayers on a surface when a molecular vapor of chemials is present. In most cases the chlorine atoms in the end of an flourinated organosilane react with -OH groups of the surface to form a chemical bond under elimination of HCL.

The Molecular Vapor Deposition tool

The MVD is located in cleanroom A-1

The Applied Microstructures MVD 100 system deposits molecular films on surfaces. These films serve a wide range of purposes ranging from antistiction coatings of nanoimprint lithography stamps to protecting MEMS structures. At DTU Nanolab the MVD is an essential tool for nanoimprint lithography, where it is used to create antistiction coatings on the imprint stamps.
