Survival Test

A single DCP tip was used to obtain 50 LAO Lithography images of Mona Lisa, and was still “alive”. Other tips may have been destroyed, but we offer the highest quality.

LAO Nanolithography was made on Ti film in Semicontact mode by NSG20 probe with conductive diamond coating.

DCP20 Mona Lisa

NTEGRA Aura system. Scan size: 8×8µm.

The thickness of lithography line was measured after the “survival” test. It is about 22nm.
