The Molecular Vapor Deposition Tool
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.
