Abstract:
A method for fabricating a metallic wire mesh touch sensor with reduced visibility. A metallic wire mesh is formed on a transparent substrate such that the surface of the metallic wires is roughened or textured, so as to cause high scattering of incident light, thereby minimizing specularly reflected light towards the user. The metal lines are formed over patterned catalytic photoresist. The rough or textured surface of the metallic wires is achieved by roughening or texturing the catalytic photoresist, by selecting parameters of electronless plating of copper, or both. An RMS surface roughness of about 50 nm would scatter approximately 70% of incident cyan light incident at 30°.
