Films having in their thickness at least two superimposed zones, including an insulating zone and a conductive zone, and the production thereof by irradiating a polymer film by means of a beam of high energy ions

摘要

The invention relates to the production of films having in their thickness at least two superimposed zones, including a semimetallic zone and an electrically insulating zone, by irradiating a polymer film by means of a high energy ion beam.PPIt is possible by this process to produce semimetal (1)/insulant (2)/semimetal (3) structures by irradiating the polymer under vacuum by means of light ions or with a limited stopping power having an energy of at least 1 MeV/amu. It is also possible to obtain insulant (4)/semimetal (5)/insulant (6) structures by irradiating, in a confined atmosphere, the polymer by means of heavy ions or ions having a high energy loss with by energy of least 1 MeV/amu. PPBy irradiating only certain zones of the film, it is thus possible to form embedded or surface-positioned electrical connections.
