THE ETCHING METHOD AND DEVICE FOR MAKING PATTERN OF THE ELECTRIC CAPACITY TYPE TOUCH SCREEN USING EXCIMER LASER

摘要

PURPOSE: A pattern etching method for an electrostatic capacity touch screen and a device thereof are provided to apply an excimer laser to a pattern mask through an optical lens to form a pattern. CONSTITUTION: An excimer laser beam is transformed into a band form through an optical lens(200). The transformed excimer laser beam transformed into the band form is applied to a pattern mask(300). An ITO film(400) is located on the lower part of the pattern mask. A pattern is formed in the ITO film using the excimer laser beam which transmits the pattern mask. In a process where a laser oscillator(100) returns to an original position after a transfer, the ITO film is transferred by a conveyor(500) in which a plurality of ITO films are placed.
