Description of the Invention: [Technical Field] The present invention provides a method of repairing pattern defects, and more particularly to a method for accurately repairing defects of a filter, a light pattern or a reticle pattern. [Prior Art] As the size of the glass substrate of the next generation of TFT-LCD panel is gradually enlarged, the development of the color filter pattern industry is also facing the problem of the expansion of the size of the glass substrate, because the color filter pattern immediately faces the pigment photoresist in the process. The difficulty of uniform coating once, and the technical obstacles to overcome in large-area high-speed coating technology; coupled with the enlargement of the substrate size, the production process parameters are complicated and the production yield is not easy to be improved. Therefore, the color filter pattern can increase the yield to effectively reduce the production cost. However, when a color filter pattern is formed on a substrate, a defect such as a defect in the color light pattern and a particulate stain is often caused by an unpredictable factor of the human or the process, and the color pattern and the light pattern are in accordance with the defect. There are different remedies than the severity of particulate contamination (iv). For example, if the color (four) pattern has too many particles or the defect is too large, the color filter pattern on the substrate may be removed and re-created (the process is repeated 1247200 to create a color filter pattern. If the color filter pattern is defective) Or if the number of particles is small, the partial repair method is generally used, for example, the color filter pattern is repaired by grinding or by using ink injection to avoid the large cost of re-manufacturing the process. Please refer to FIG. 1 and FIG. Fig. 1 and Fig. 2 are schematic views showing a conventional method of repairing a filter pattern by grinding. As shown in Fig. 1, a transparent substrate 1 comprising a plurality of filter patterns 12 arranged in an array is arranged (referred to as CF). a substrate, and a plurality of black matrix 14 disposed between the adjacent filter patterns 12, wherein the plurality of filter patterns 12 arranged in an array are red filter patterns and green filters The pattern and the blue filter pattern are composed. As described above, since the filter pattern 12 is prone to defects, if the defect is larger than the allowable size, such as the protrusion defect 16 alone. Then, a grinder 18 is used for grinding to remove a part of the protrusion defect 16. As shown in Fig. 2, the protrusion defect 16 is ground by the grinder 18 so that the protrusion height is aligned with the filter pattern 12 or lowered to a predetermined height. However, the above-mentioned technique of repairing the filter pattern by the grinding method has a problem that the height of the protrusion defect is ground to a certain height, so if the protrusion defect is too large, the entire repair process takes too long, which is disadvantageous. Cost, 1247200 In addition, since the protrusion defects are still on the filter pattern, it affects the color chromaticity or saturation of the color, etc. Please refer to Figures 3 to 5, and Figures 3 to 5 show the conventional use of injection ink. A schematic diagram of a method for repairing a filter pattern. As shown in FIG. 3, a transparent substrate 30 includes a plurality of filter patterns 32, and a plurality of black filter patterns 34 are disposed between adjacent filter patterns 32, wherein The filter patterns 32 are composed of a red filter pattern, a green filter pattern, and a blue filter pattern. When the filter pattern 32 has a protrusion defect 34, the laser beam 38 is used first to expose the protrusion defect 36. In addition, the filter pattern 32 is repaired. As shown in FIG. 4, when the protrusion defect (not shown) of the filter pattern 32 is removed, a notch 40 is formed, and a needle 42 is used to fit the color ink. 44 is dropped into the notch 40 on the filter pattern 32, and the notch 40 is filled. Finally, as shown in Fig. 5, a baking process is performed to cure the ink 44 in the notch 40, and finally the cleaning liquid is used to cover the notch 40. Part of the cleaning and removal. Due to the above-mentioned technique of repairing the filter pattern by the method of injecting ink, it is easy to cause the ink to diffuse to other filter patterns that do not need to be repaired, so that the filter pattern cannot be properly repaired, and it is necessary to use a suitable cleaning solution. Cleaning the ink that has spread to other filter patterns, and during this cleaning process, the filter pattern or the repaired filter pattern that is not repaired may be broken again in 1247,200 b, and the lion is close to two. More than one kind of light pattern, and only the water-like method also causes color mixing to cause chromaticity or color saturation, and the ink filter pattern is repaired. ",, to successfully integrate the above-mentioned conventional technique of repairing the filter pattern, since the entire process of repairing the light pattern takes too long, the protrusion cannot be surely removed, and the cleaning liquid is required, the production cannot be effectively reduced. The time and cost of the filter chart. [Review] In view of the above, it is an object of the present invention to provide a method for repairing the defects of the calender pattern to avoid the disadvantages of the conventional repair of the calender pattern. - The object is to provide a method of repairing defects of a reticle pattern to reduce the cost of fabricating a reticle pattern. To achieve the above object, the present invention provides a method of repairing defects in a enamel pattern and a reticle pattern. - Repair the dry film (4) Also (4) Kiss film) Place the (4) light pattern or reticle pattern, and repair the dry film to cover the filter pattern or reticle pattern and defects, and then carry out a transfer process, 1247200 will be located on the defect The repaired dry film is transferred into the defect, and finally the repaired dry film that has not been transferred into the defect is removed. [Embodiment] Please refer to Fig. 6 to Fig. 9 6 to 9 are schematic views showing a method of repairing defects of a filter pattern according to a preferred embodiment of the present invention. As shown in FIG. 6, a transparent substrate 110 includes a plurality of filter patterns 112, and a plurality of The black filter pattern 114 is disposed between the adjacent filter patterns 112, wherein each of the filter patterns 112 is composed of a red filter pattern, a green filter pattern, and a blue filter pattern. When the filter pattern 112 appears When the defect 116 is protruded, the protrusion defect 116 is first removed using the laser beam 118, and the filter pattern 112 is repaired. Next, as shown in Fig. 7, after the protrusion defect (not shown) on the surface of the filter pattern 112 is removed A gap 120 is formed on the surface of the filter pattern 112. At this time, a repair dry film 122 is used to cover the gap 120 and the filter pattern 112, and a pre-pressing process is performed, for example, using a laminator or using air pressure. The repaired dry film 122 is adhered to the filter pattern 112. The repair dry film 122 includes a base film 124 and a repair pigment layer 126, and the repair dry film 122 uses red depending on the filter pattern 112 to be repaired. Dry film, green repair dry film or blue repair dry film. 1247200 Next, as shown in Fig. 8, a micro-hot stamping head 128 is used for hot pressing on the notch 120, and the high temperature of the micro-heating head 128 is located in the gap. The repaired dry film 122 on the 12th layer is melted, whereby the repaired dry film 122 is transferred into the notch 2〇, and the notch 120 is filled, so that the dry film 122 can be repaired and adhered to the notch 120 without falling off. The shape and size of the opening and the size of the micro-calendering head 128 are matched with the shape and size of the notch 12 最后. Finally, as shown in Fig. 9, the repairing dry film 122 is peeled off, that is, the repair of the filter pattern 112 is completed. It should be noted that if there are no defects such as protrusion defects 116 or foreign matter on the filter pattern 112, but defects including recesses are included, the steps of removing the protrusion defects 116 or foreign matters by the laser beam Π 8 may be omitted. It can be directly implemented from Fig. 7 to Fig. 9. Referring to Fig. 10 and Fig. 11, FIG. 1 and FIG. 11 are schematic views showing a method of repairing a defect of a filter pattern according to another preferred embodiment of the present invention. The difference from the above embodiment is that the present embodiment uses a light beam to repair the dry film transfer action, such as laser light, ultraviolet light (UV light) and other light sources of different wavelength forms, thereby removing the protrusion of the filter pattern. The steps of the defect are the same as those shown in the sixth to seventh embodiments of the above embodiment, and will not be further described herein. 11 1247200 As shown in FIG. 10, after the filter pattern 212 forms a notch 220, the notch 22〇 of the filter pattern 212 is irradiated by a light beam 228 to heat the repaired dry film 222 located on the notch 220 to repair the dry film. 222 is transferred into the gap 220 and the notch 220 is filled. The repaired dry film 222 includes a base film 224 and a repair pigment layer 226, and the repair dry film 222 is modified according to the filter pattern; the red repair dry film, the green repair dry film or the blue repair dry membrane. Finally, as shown in Fig. 11, the repaired sweet film 222 is peeled off, that is, the repair of the filter pattern 212 is completed. In the above embodiments, the color filter pattern is taken as an example to illustrate the method of the present invention. However, the method of the present invention is not limited to repairing the color of the light-passing pattern, and may be utilized if the black filter pattern is defective. The method of the present invention is combined with a black repair dry film to repair black filter and light patterns. In addition to this, the method of the present invention can also be applied to the defect of repairing the mask pattern. As shown in Fig. 12, a reticle substrate 230 is provided which includes a plurality of reticle patterns 232 whereby the reticle substrate 230 forms an opaque region. The mask substrate 230 is made of a light-transmitting material such as glass or quartz, and the mask pattern 232 is made of an opaque material such as chromium and a compound thereof. In the manufacturing process or in the transportation process 12 1247200, the reticle pattern 232 may be damaged due to environmental or other unpredictable factors, so that the reticle pattern 232 is transparent. The method of the method of I and the month and the method of repairing the defect of the reticle pattern by the opaque material (for example, black repair dry film) is the same as the steps shown in the seventh embodiment to the ninth embodiment of the above embodiment, and is not here. More than enough.
