Claim:
1. A method of forming a metallic pattern on a polymer substrate, comprising: providing a polymer substrate, wherein a material of the polymer substrate includes nylons, polycarbonates (PC), acrylonitrile butadiene styrene (ABS), PC/ABS, polyethylene terephthalate (PET), polyether ether ketone (PEEK), polytetrafluoroethylene (PTFE) or liquid crystal polymers (LCP); forming a mixture layer on a surface of the polymer substrate, wherein the mixture layer includes an active carrier medium and nanoparticles dispersed in the active carrier medium, wherein a material of the active carrier medium includes polyvinylpyrrolidone (PVP) or polyethylene oxide (PEO); fusing the nanoparticles in a portion of the mixture layer by treating the mixture layer with a laser process for forming a conductive pattern on the surface of the polymer substrate, wherein the nanoparticles are fused together through the heat generated from the nanoparticles during the laser process, and wherein the laser process is performed by using a UV laser at 355 nm with a power of 0.2˜0.4 W and 80% overlapping and the laser process is a laser ablation process; performing a cleaning process to remove an untreated portion of the mixture layer to expose the surface of the polymer substrate, while the conductive pattern is remained on the surface of the polymer substrate; and subjecting the conductive pattern on the polymer substrate to an electroplating process to form the metallic pattern on the conductive pattern.
