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. | The Applied Microstructures MVD 100 system deposits molecular films on surfaces.

At Danchip the MVD is essential for nanoimprint lithography. | ||
== Processing on the MVD == | |||
The MVD coatings are created as self-assembled monolayers on a surface when a molecular vapor of chemials is present. These chemicals typically have a teflon-like tail consisting of -(CF<sub>2</sub>)<sub>x</sub>CF<sub>3</sub> and, in the other end, a reactive group -Si(Cl<sub>x</sub>)<sub>3-x</sub>. | |||
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. | |||
