Speeding innovation for industry
Success | Micro-nanoelectronics
Arnano uses a number of advanced processes
to make its products. The company employs
techniques like PVD, thermosensitive lithography,
direct photolithography, and deep engraving on
substrates like sapphire, ceramic, quartz, and
Zerodur®. The company has had a joint lab with
Leti since 2010 and holds licenses to around ten of
the institute’s patents.
The company makes decorative parts for fine
timepieces on sapphire, quartz, or engineered glass.
The micron-resolution of Arnano’s engravings
makes it possible to create images in greyscale and
to hide authentication marks.
And, for data archiving, Arnano can engrave the
content of 10,000 A4 pages (the equivalent of a 1.5
meter stack of paper) onto a Nanoform, or 200-mm
The deep, precision engraving of hard materials
has applications on a number of markets, from
decorative parts for the luxury industries to
microfluidics and optics, where it can be use
