Abstract
Electrically conductive paths are produced on a polymeric substrate by laser writing, i.e., by tracing desired paths on the substrate by a laser beam. The resulting paths comprise electrically conductive carbon as produced by thermal decomposition of substrate surface material; the paths can serve; e.g., as electrical interconnections akin to printed circuitry on a wiring board. Optionally, the conductivity of paths can be enhanced by electroplating a suitable conductor metal or alloy onto the paths.
