Complex 3D-nano patterns with indentation lithography and piezo technology
(Nanowerk News) A collaboration between the Whitesides Group at Harvard University and
CSM Instruments has culminated in an important advance in lithography of different
materials at the nanoscale. The motivation for this development was the ability to
produce unique lithographical patterns of different shapes and sizes for use in
research applications (e.g. lab-on-a-chip) where conventional techniques such as
electron-beam lithography (EBL) and photolithography cannot be used. The new
method utilizes the standard Ultra Nanoindentation Tester (UNHT) and the
Nano Scratch Tester (NST) without anymodification.
The precise shape of the patterns is achieved with a PI (Physik Instrumente) P-733.2CD piezo nanopositioning scanning stage which is mounted directly on the Open Platform and allows sub-nanometer
positioning resolution in the X and Y axes.

CSM Instruments has been leader in the development of instruments for surface mechanical properties characterization for over 30 years in both research and industrial fields. CSM Instruments provides equipment that allow the mechanical characterization of a wide range of surfaces and bulk materials. Adhesion of paints, optical thin films or hard coatings can be defined using one of our Scratch Testers. These span the nano to the macro range to analyze the widest range of materials.
