  • Method of forming double-sided patterns in a touch panel circuit
    Patent number: 8414783
    Abstract: A method of forming double-sided patterns in a touch panel circuit is disclosed. A first conductive layer and a second conductive layer are respectively formed on both sides of a substrate. A blocking layer is formed on a top surface of the first conductive layer for blocking ultraviolet (UV) light. A first photoresist layer is formed on a top surface of the blocking layer, and a second photoresist layer is formed on a bottom surface of the second conductive layer. Accordingly, two sides of the substrate may be exposed, developed and etched at the same time, thereby substantially simplifying the process of manufacturing the touch panel circuit.
    Type: Grant
