Abstract

Rewriting process of lower electrical resistance lines on a titanium dioxide (TiO2) film was developed. In this process, lower electrical resistance lines were written on a TiO2 film without producing their surface topography changes by femtosecond laser irradiation. By heating with an electrical furnace under air, the electrical resistance of these lines was come back to the higher resistance with no topography changes. This result indicated that the lines could be erased by the heating method under air. When the erasing-treated area was irradiated with a femtosecond laser, the lower electrical resistance lines could be rewritten with no topography changes of the film surface.
