Patent ID: 8568599

Claim:
A method of fabricating a touch panel, comprising the steps of: forming a first conductive layer, a second conductive layer and a first photo-resist layer on a substrate sequentially; applying a first gray-level mask to pattern the first photo-resist layer; using the patterned first photo-resist layer to etch the first conductive layer and the second conductive layer so as to define a plurality of first sensing electrodes of the touch panel; forming a first insulation layer on the substrate and the first sensing electrodes; applying a second gray-level mask to pattern the first insulation layer so as to form a patterned first insulation layer having different thicknesses, wherein the patterned first insulation layer over the first sensing electrodes has the largest thickness; forming a third conductive layer on the patterned first insulation layer; forming a second photo-resist layer on the third conductive layer; patterning the second photo-resist layer to expose partial the third conductive layer; and using the patterned second photo-resist layer to etch the third conductive layer so as to define a plurality of second sensing electrodes of the touch panel.
