MANUFACTURING METHOD HIGH INTEGRATED CAPACITIVE TOUCH SENSOR

摘要

The present invention relates to a manufacturing method of a capacitive touch sensor, comprising a step of preparing original plate glass; a step of reinforcing the original plate glass; a step of forming a touch sensor layer on the lower part of the reinforced original plate glass; a step of forming a mask layer in a cell unit on the upper and lower parts of the reinforced original plate glass with the touch sensor layer; a step of half-etching the reinforced original plate glass except for the mask layer region; a step of forming a glass substrate in the cell unit by cutting the reinforced original plate glass in the cell unit; a step of separating the glass substrate in the cell unit, cutting an edge part of the glass substrate in the cell unit by ion-beam etching and microblast processes, and forming a chamfering unit; and a step of chemically etching the edge part of the glass substrate in the cell unit and removing the mask layer. Accordingly, the present invention improves productivity and yield through the increase in the number of cells for the same original plate glass by forming a narrow cell gap less than or equal to 0.5 mm with a process of full-cutting the original plate glass after half-etching the original glass plate.
