Polymer layer comprising silicone and at least one metal trace and a process of manufacturing the same
The invention relates to a method of embedding a metal trace in a silicone containing polymer layer, by the steps of applying an agent that does not adhere to a substrate; applying a polymer layer on the non adhering agent; irradiating a surface of the polymer with a light beam emitted by an excimer laser creating cuts, grooves, blind holes or vias; immersing the irradiated polymer in an autocatalytic bath containing metal ions and metallizing the polymer; thermally treating the metallized polymer layer to induce diffusion of the metalized metal into the first polymer layer; applying a polymer layer on the thermally treated metallized polymer; and thermally treating the metallized polymer.
