<title>Direct laser writing of conductive pathways into diamond-like carbon films</title>

Abstract

Continuous wave laser microprocessing of diarrnd-1ike carbon films deposited on silicon is reported The conductive lines of 3-15 pm width with resistivity Lj . jo—2 ccm were formed into dielectric amcrphous film via its graphitization as evidenced by Rarnan spectroscopy. When the temperature within a laser spot rises up to 6000C the carbon oxidation starts, resulting in the film etching and the narrow channels formation The reflectivity in visible of the anneal ed DLC fi ims I s studied regarding them as a candidate for optical recording ridia.
