PREPARING METHOD OF STAMPER FOR PRODUCING LIGHT GUIDE PLATE

The present invention provides a manufacturing method of template. The present invention is related to the template for manufacturing a light guide plate and is used to replace the triangular protuberance parallel type, in which the lenticular lens shape formed through the use of the vertical and the horizontal lens shapes is used as the pattern mold shape of the template. The characteristic of the present invention comprises: a cleaning step for cleaning a plate-shaped glass; the coating step for coating a photo-sensitive film on the cleaned glass in a spin-coating method; a thermal treatment step to perform thermal treatment (soft bake) onto the coated photo-sensitive film; an exposure step, in which exposure is performed after the pattern mask of the vertical and the horizontal forms are loaded; a development step to perform development process onto the photo-sensitive film that is completed with the exposure step; a manufacturing step of lens shape, in which thermal treatment (hard bake) is performed onto a part where the light-sensitive film is removed to form the lens shape of the vertical and the horizontal forms; an deposition step to deposit an conductive film (such as Cu, Ni, and so on) on the manufactured of the finished shape; a manufacturing step of a female mold, in which nickel is plated on the finished patterned metal (Cu, Ni and son on) surface to manufacture the female mold; and a manufacturing step of a template, in which a mold releasing process is performed onto the female mold and electroplating process is used to manufacture the template.
