A product semiconductor wafer has integrated circuits separated by scribe lines. The polymeric fluorescent substance is excellent in solubility to organic solvents, and has higher efficiency and longer lifetime in applying as a polymer LED. A low dissipation factor dielectric layer is deposited onto said first conducting layer. The second plane is positioned upwardly of the first plane. A private access point sends indication information to a mobile station that includes available services provided by the private access point. The method of manufacturing conductive fibers of the present invention not only is simple and easy but also requires low production costs.
