Claim:
1. A method of making a touch screen panel, comprising: providing a substrate assembly comprising a substrate, first sensing electrodes formed over the substrate and arranged in rows extending along a first direction, and second sensing electrodes formed over the substrate and arranged in columns extending along a second direction intersecting with the first direction, the first sensing electrodes arranged in each of the rows being connected to each other; providing a multi-layered film comprising a first conductive photosensitive layer, a second conductive photosensitive layer, and an insulation photosensitive layer having a light sensitivity different from that of at least one of the first and second conductive photosensitive layers; forming insulators by exposing and developing the insulation photosensitive layer; forming bridges and insulators by exposing and developing the second conductive photosensitive layer; and assembling the substrate assembly and the multi-layered film comprising the insulators and the bridges such that each bridge connects two immediately neighboring second sensing electrodes and each insulator insulates one of the bridges and the first sensing electrodes.
