METHOD FOR PRODUCING A THREE-DIMENSIONAL CONDUCTOR TRACE STRUCTURE AND A CONDUCTOR TRACE STRUCTURE PRODUCED ACCORDING TO THIS METHOD

摘要

The invention relates to a method for producing a conductor trace structure (4) on a dielectric carrier material (1). The carrier material (1) is first furnished with a flat coating (2). Nanoscale particles containing a substantial material content of metal oxides such as copper oxides, which are coated with a suitable reduction agent, are contained in the coating (2). Then, the coating (2) is exposed selectively to an electromagnetic radiation from a laser (3). Due to selective action of radiation, this results in a sintering of particles contained in or generated in situ in the coating (2), producing the conductive trace structure (4).
