Abstract

In order to process a carbon film carbon is deposited on a substrate by sputtering from a carbon sputter target in a gas mixture which contains nitrogen in a minimum proportion of 20% and a sputter gas at a predetermined gas pressure and the substrate is then subjected under a high vacuum to thermal treatment at a temperature above 100.degree. C. The carbon films produced in this manner comprise a fiber and/or tube structure which extends substantially perpendicular to the film.
