Claim:
A method for forming a touch sensing pattern and signal wires, comprising the steps of: installing a first and a second conductive plating films on a surface of a highly transparency substrate; projecting a high energy light beam to the conductive plating films; and the high energy light beam moving with respect to the substrate along a predetermined track; a plurality of insulating trenches being formed in the first and second conductive plating films so as to form predetermined patterns for a sensing area and a wire area; a yellow light process being performed on the substrate; a layer of light resistor thin film being formed on a surfaces of the wire area; and wherein the yellow light process further including the following steps: a layer of light resistor thin film being coated upon a surface of the conductive plating film; locating the high transparent substrate in a furnace; hot wind of 60° C.˜90° C. being blown to the light resistor thin film about 100 to 140 seconds; then the temperature is reduced gradually to be about 25° C.; exposing the light resistor thin film by using an ultraviolet light source with an energy of 150˜250 MJ/cm2; a light mask being installed between the light resistor thin film on the wire area and the light source being retained with a distance of 30 μm˜80μm; and the light resistor thin film being exposed; and a wire pattern on the light mask being transferred to the light resistor thin film; and a developing agent with a pressure of 0.5 Kg/cm2 being applied to the light resistor thin film for solidifying the exposure area of the light resistor thin film; then a cleaning agent of 0.5 Kg/cm2 being used to clean the un-exposing part of the light resistor thin film so as to remove the light resistor on the un-exposing area of the light resistor thin film to form as a layer of solidified light resistor thin film on the wire area of the substrate; and etching the first conductive plating film in the sensing area; by above steps, the predetermined pattern in the sensing area being formed in the second conductive plating film; and the first and second conductive plating films being existed in the wire area with a predetermined pattern.
