NanoImprint

Principe de la nano-impression

The principle of this new-generation lithography technique is simple: it is to replicate nanoscale patterns uysing moulding


Since July 2010, LAAS is equipped with specifically dedicated nano-imprint machine, a Nanonex NX-2500. Thisequipment allows thermal or UV methods.
