激光输出调整装置及方法技术领域 本发明涉及一种激光输出调整装置及方法。 Laser output adjusting device and method Technical Field  The present invention relates to an apparatus and method for adjusting the laser output. 具体为，通过由第一测定部和第二测定部对在激光部生成的激光光束进行测定，可容易地对照射在基板上的激光光束的输出能量进行调整的激光输出调整装置及方法。 Specifically, by adjusting the laser output measuring apparatus and method for a first portion and a second portion for measuring the laser beam generated by the laser measuring unit, the output energy can be easily irradiated with laser beam on a substrate for adjusting. 背景技术 近年来，随着平板显示器装置，尤其是在液晶显示器（LCD)的需求的增加和大型化的趋势，其应用程度、尺寸增大及分辨率增加的速度也在加快，且为提高生产效率并实现价格的低廉化，在简化制造工艺和提高收益率方面付出了很多努力。  In recent years, a flat panel display device, in particular an increase in the demand trends and large liquid crystal display (LCD), the extent of the application, and the size is increased to increase the resolution also accelerating the speed, and in order to improve production efficiency and a cost reduction of price, in terms of simplifying the manufacturing process and improve the yield paid a lot of effort. 液晶显示器的基本结构， 由形成有黑色矩阵、彩色滤光膜和共同电极的上部基板，及形成有像素区域、像素电极、开关元件和线路的下部基板，以及填充于所述上部基板和下述基板之间的液晶所构成。 The basic structure of a liquid crystal display, the black matrix is formed, the upper substrate color filter and a common electrode, and a pixel region is formed, a lower substrate having a pixel electrode, a switching element and wiring, and the upper substrate and filled in the following a liquid crystal between the substrates formed.  这种在下部基板上形成的结构组成成分，导致在制造工艺中出现线路的断线或短路等不良现象，且随图像元件显示面积的大型化，这种缺陷也越来越多，因此，为提高液晶显示器的质量和稳定性，需要可消除这些缺陷的修补（R印air)技术。  This structure is formed on the lower substrate composition, resulting in a disconnection or short circuit and the like undesirable phenomenon in the manufacturing process, and the display element with the image size of the area, more and more of such defect, Therefore, to improve the quality and stability of the liquid crystal display, a need to eliminate these drawbacks repair (R AIR printing) technology.  一直备受瞩目的修补技术是，具备修补用的备用线路，在发生缺陷时，连接备用线路对断线进行修补的方法，但若修补线路过长时，信号水平会因线路电阻值而降低，从而对液晶面板的动作特性产生不利影响。  been highly anticipated repair technique is provided for repairing a backup line, when the defect occurs, the spare line pair connected to a method of repairing the disconnection, but if the line is too long repair time, the signal level due to line resistance value It is reduced, thereby adversely affecting the operation characteristics of the liquid crystal panel.  因此，最近较受欢迎的是使用激光化学气相沉积法的修补线路法。  Therefore, recently more popular method is to use a laser repair line chemical vapor deposition method. 即，基本上是采用在发现缺陷时，利用激光来切断缺陷部位的某一部位，并通过化学气相沉积法来沉积修补线路并形成图案的方法，或是在线路断线时，通过激光化学气相沉积法（Laser CVD)沉积金属，从而使断开的线路电连接的方式，进而完成修补作业。 That is, which is basically a defect is found at the site, using a laser to cut the defect site, and repair line deposited by chemical vapor deposition and a method for forming a pattern, or when the line disconnection by laser chemical vapor depositing a metal deposition method (Laser CVD), thereby electrically disconnecting the line connections, thereby completing the repair work. 这种激光化学气相沉积法修补方法的优点在于，断线时可立即在断线部位按所期望的形状生长金属线路，其修补工艺简单，且可进行包括光栅线路和数据线路在内的各种修补作业。 The advantage of this method of repairing a laser chemical vapor deposition in that immediately shape as desired growth of the metal lines, in which the process is simple repair broken when disconnected portion, and may include a variety of raster and data lines, including repair work. 而且，激光化学气相沉积法不仅可修补基板的缺陷，还可用于微细线路的沉积工艺。 Further, the laser chemical vapor deposition of a substrate not only to remedy defects, may also be used in fine-line deposition process.  参照图1，现有的激光化学气相沉积法装置中，在激光部100生成的激光光束10经过光学部200，在从加工部300照射到基板20的过程中，由加工部测定器310对其输出值进行测定。  Referring to FIG. 1, a conventional laser chemical

processing unit measuring instrument 310 measured value of its output. 但激光光束10输出能量减少的现象发生时，则很难判断造成激光光束10输出能量减少的部位。 However, when the laser beam 10 to reduce the output power of the phenomenon, it is difficult to cause the laser beam 10 is determined to reduce the energy output portion. 另外，还存在难以将减少的激光光束的输出能量重新调整所需强度的难题。 Further, it is difficult to reduce the output power of the laser beam to re-adjust the desired intensity problems.  另外，除了激光化学气相沉积法装置之外，对切断发生短路的不良线路对缺陷进行修补的一般激光装置，及用激光照射显示器的缺陷像素使其暗点化后对缺陷进行修补的高像素修补（HPR)装置等来说，准确保持使用者所期望的激光输出强度，在确保工艺可再现性和稳定性方面，尤为重要。  Further, in addition to the laser chemical vapor deposition apparatus, disconnection of short-circuit failure occurred the defect of conventional laser repair apparatus, so that the dark pixel and the defect repairing attunement laser irradiation defect of the display high-resolution devices patch (the HPR), the accuracy desired by the user holding the laser output intensity, to ensure process reproducibility and stability, is particularly important. 发明内容 因此，本发明旨在解决上述现有技术存在的各种问题，目的在于提供一种在激光的沉积和修补工艺中，使激光光束的输出能量始终保持一致的激光输出调整装置及方法。  Accordingly, the present invention aims to solve the various problems of the

deposited in a fine-line portion of the laser irradiation of light.  第一测定部400设置于激光部100与光学部200之间。  The first measurement portion 400 is disposed between the laser unit 100 and the optical portion 200. 第一测定部400可对生成在激光部100且照射到光学部200上的激光光束的输出能量进行测定，其可包括将光能变换成电能的光电变换元件中的一种，即光电二极管（photo diode)。 The first measuring section 400 to be generated in the laser irradiated portion and the laser beam 100 on the

第二测定部500可设置于光学部200的内部。  The second measuring section 500 may be provided inside the optical unit 200. 第二测定部500对经过光学部200 并照射到加工部300上的激光光束10的输出能量进行测定，和第一测定部400同样，还可包括光电二极管。 The second elapsed measuring section 500 and the optical portion 200 to the output energy of the laser beam is irradiated on the workpiece 10 is measured 300, and a first measuring section 400 similarly also comprises a photodiode.  控制部600接收第一测定部400和第二测定部500测定的激光光束10的输出信号，对接收的输出信号进行分析，从而为调整在激光部100生成的激光光束10的输出能量而向激光部100发送信号。  The control unit 600 receives a first signal measurement unit 400 and outputs a second measurement portion 500 measures the laser beam 10, the received output signal is analyzed, so as to adjust the energy output of the laser beam generated by the laser 100 10 It transmits a signal to the laser unit 100.  控制部600还包括显示部(无图示)，其可对从第一测定部400和第二测定部500接收到的激光光束的输出信号，和向激光部100发送的信号进行数值化处理并予以显示。  The control unit 600 further includes a display unit (not shown), the output signal may be

图3为本发明的实施例所示的在第一测定部400上对激光光束11的输出能量进行测定的示意图。 Measuring the laser output energy : Example  FIG. 3 is a schematic view of the present invention will be measured on the output energy of the laser beam 11 is shown in the first measurement section 400.  本发明的一实施例所示的第一测定部400，在生成于激光部100的激光光束10照射到光学部200之前，可直接对激光光束10的输出能量进行测定。 Measuring a first embodiment of a portion  of the present invention illustrated embodiment 400, prior to generating the laser irradiation unit 10 of the laser beam 100 to the optical unit 200 may output energy of the laser beam 10 is measured directly.  一方面，依照其他实施例所示，激光光束10的输出能量可在第一测定部400间接测试。  In one aspect, in accordance with other embodiments, the output energy of the laser beam 10 a first measurement portion 400 may be in an indirect test. 图3所示的是，激光光束10的输出能量被射束分离器（beam splitter) 410和覆盖板420反射，而间接地在第一测定部400测定的示意图。 Shown in FIG. 3, the output energy of the laser beam 10 is a beam splitter (beam splitter) 420, and a reflective cover plate 410, 400 in a schematic view of indirectly measuring the first measurement portion.  参照图3,激光部100和光学部200之间设置有第一射束分离器410。  Referring to FIG 3, the laser unit is provided with a first beam splitter 100 and the optical portion 410 between the 200.  第一射束分离器410可对经过第一射束分离器410的激光光束10进行分离。  The first beam splitter 410 may be a laser beam 410 passes through the first beam splitter 10 is separated. 即激光光束10的一部分通过第一射束分离器410被反射，其余部分则按原来的路径而照射到光学部200。 That portion of the laser beam 10 through the first beam splitter 410 is reflected, the rest of the press original irradiated to the optical path portion 200. 若经第一射束分离器410分离并被反射的激光光束11的输出能量过大，则工艺上所使用的激光光束10的输出能量就会过小，达不到本发明保持激光光束10始终一致的目的，若经分离并反射的激光光束11的输出能量过小，则在第一测定器400上对激光光束11进行测定时，误差范围会变大，因此，经分离并反射的激光光束11的输出能量占全部输出能量的1%至2%时为最佳。 If the output of the laser beam 11 is separated by the first beam splitter 410 and reflected too much energy, the output energy of the laser beam 10 used in the process will be too small, not always up to 10 of the present invention keep the laser beam the same purpose, if the output energy and the separated reflected laser beam 11 is too small, when the laser beam 11 is measured, the error becomes larger in a first range measurement device 400, therefore, separated and the reflected laser beam optimum energy output 11 accounts of all 1-2% of the output energy.  另外，在激光部100和光学部200之间，除了第一测定部400和第一射束分离器410外，还可能包括覆盖板420。  Further, between the laser unit 100 and the optical portion 200, in addition to the first measurement section 400 and a first beam splitter 410, but it may also include a cover plate 420. 覆盖板420使经第一射束分离器410分离并反射的激光光束11再次反射到第一测定部400上，进而使第一测定部400对激光光束11的输出能量测定变得容易。 That the cover plate 420 through the first beam splitter 410 and separated again reflected laser beam 11 reflected on the first measurement portion 400, and thus the output energy of the laser beam 11 in the first measurement section 400 can be easily measured. 覆盖板420的材质只要是可以反射激光光束11的材质，即可不加限制地使用。 Cover plate 420 as long as the material can reflect a laser beam 11 of a material can be used without limitation. 图3中为更好地进行说明，图示了覆盖板420只覆盖开放侧面的一部分，但覆盖的面积可根据发明的利用形态而不同。 FIG 3 will be described for better illustrating the cover portion 420 covers the open sides of the plate, but the area can be covered according to the invention using different forms.  图4为本发明的实施例所示的在第二测定部500上对激光光束12的输出能量进行测定的示意图。 A schematic view of a second measurement in the measuring section 500 on the output energy of the laser beam 12 in the embodiment shown in  FIG. 4 of the present invention.  如图4所示，本发明一实施例的第二测定部500可直接对从激光部100照射到光学部200并经过光学部200的激光光束10的输出能量进行测定。  As shown in FIG 4, the present invention is a second embodiment of the measurement portion 500 may be measured directly and through the output portion of the optical energy of the laser beam 200 of laser beam 10 is irradiated to the optical portion 100 from portion 200.  另外，根据其他实施例，激光光束10的输出能量可由第二测定部500来间接测定。  Further, according to other embodiments, the output energy of the laser beam 10 may be an indirect measurement of the second measurement section 500. 图4显示的是，激光光束10的输出经第二射束分离器510反射后，经过散射器520并在第二测定部500进行间接测定的示意图。 FIG. 4 shows, the 510 reflection of the laser beam output by the second beam splitter 10, passing through the diffuser 520 and schematic measured indirectly in the second measurement portion 500.  参照图4，光学部200内设有第二射束分离器510。  Referring to FIG 4, the optical unit 200 equipped with a second beam splitter 510.  第二射束分离器510可对通过第二射束分离器510的激光光束10进行分离。  The second beam splitter 510 may be separated by the laser beam of the second beam splitter 510 10. 即， 部分激光光束10被第二射束分离器510反射，其余部分按原来的路径经过光学部200而照射到加工部300上。 That is, part 10 is reflected by the second beam splitter 510 a laser beam, the rest of the unit 200 through the optical path by the original is irradiated on the processing unit 300. 若被第二射束分离器510分离并反射的激光光束12的输出能量过大， 工艺上所使用的激光光束10的输出能量就会过小，这样达不到本发明的保持激光光束11 始终一致的目的，若经分离并反射的激光光束12的输出能量过小，则在第一测定器500上对激光光束进行测定时，误差范围会变大，因此，优选被分离并反射的激光光束12的输出能量占全部输出能量的1%至2%。 If they are separated from the second beam splitter 510 and the reflected laser beam output 12 becomes excessive, the output energy of the laser beam 10 on the process used will be too small, so that 11 of the present invention can not always keep the laser beam the same purpose, if the output energy and the separated reflected laser beam 12 is too small, when the laser beam was measured, the error becomes larger in a first range measurement device 500, therefore, it is preferably separated and reflected laser beam output energy accounts for 12% to 2% of the total. 1 output energy.  另外，在第二测定部500和第二射束分离器510之间，即在第二测定器500的侧面可安装散射器（diffuser) 520。  Further, between the second measurement portion 500 and a second beam splitter 510, i.e. the side of the second measuring device 500 may be installed diffuser (diffuser) 520. 光学部200的内部可设置有电荷耦合器（CCD :charge coupled device)530，为防止从第二射束分离器510分离到第二测定部500的激光光束12 反射到第二测定部500的表面而被射到电荷耦合器530，安装散射器520。 Inside the optical portion 200 may be provided with a charge coupled device (CCD: charge coupled device) 530, 510 to prevent the separation from the second beam splitter 12 reflects the laser beam to a second measurement portion 500 to the surface 500 of the second measurement unit is incident on CCD 530, the diffuser 520 is mounted. 另外，散射器520 的作用在于，可更精密地测定激光光束12的输出能量。 In addition, the role of the diffuser 520 is that the output energy of the laser beam can be determined more precisely 12. 图5为本发明一实施例的在散射器上的激光光束扩散的示意图。  FIG. 5 is a schematic example of a laser beam on the diffuser, a diffusion of the embodiment of the present invention.  参照图5，被第二射束分离器510分离并反射的激光光束12在经过散射器520时， 在散射器520内部充分扩散12'后，照射到第二测定部500的表面上。 After  Referring to Figure 5, separated by the second beam splitter 510 and the reflected laser beam passing through the diffuser 12 at 520, 520 in a sufficiently diffused inside the diffuser 12 'is irradiated onto the measurement surface of the second portion 500 of the . 因激光光束10被第二分离器510分离和反射，因此，激光光束12具有较小的输出能量，有可能出现测定误差， 但经过散射器520的激光光束12'广泛地分布在第二测定部500的表面上，从而可提高测定的准确度。 10 are separated by 510 and the laser beam reflected by the second splitter, and therefore, the laser beam 12 having a small output power, measurement errors may occur, but after the laser beam 12 of the diffuser 520 'are widely distributed in the second measurement portion upper surface 500, thereby improving measurement accuracy.  散射器520的尺寸优选根据第二测定部500的大小而制作，以完全覆盖第二测定部500的侧面。  The size of the diffuser 520 is preferably produced according to the size of the second measurement section 500, so as to completely cover the side surface portion 500 of the second measurement. 另外，散射器520的材质可为熔融石英（fused silica，FS)。 Further, the diffuser 520 may be made of fused silica (fused silica, FS). 熔融石英具有优异的光学性质及抗激光损伤性，因此，作为基于激光的光学系统中的光学构件而被广泛使用。 Fused silica has excellent optical properties and resistance to laser damage resistance, and therefore, as an optical member of the laser-based optical systems are widely used. 将散射器520的一面或两面可加工成每Imm有240沙（grit)，这样在使用时，对激光光束12的扩散效果会更加明显。 The diffuser 520 can be processed into one or both surfaces of each sand Imm 240 (Grit), so that in use, will become more apparent diffusion effect of the laser beam 12.  另外，优选散射器520被安装成与第二测定部500的侧面呈规定角度A倾斜。  Further, the diffuser 520 is preferably mounted to the side surface 500 of the second measurement unit A is inclined a predetermined angle. 在第二测定部500的侧面上，直接安装散射器520的情况(规定角度A为0°时)下，激光光束12在散射器520表面上轻微反射并被传到电荷耦合器530上。 On the side portion 500 of the second measurement, the scattering is directly mounted 520 (when the predetermined angle A is 0 °), the laser beam 12 reflected and transmitted light on the CCD 530 on the surface of the diffuser 520. 为防止这种现象的发生，散射器520优选被安装成与第二测定部500侧面呈大于0°且小于45°的角度A倾斜，更优选倾斜20°。 To prevent this phenomenon, the diffuser 520 is preferably mounted to the second side surface shape measurement portion 500 and greater than 0 ° and smaller than the inclination angle A of 45 °, more preferably inclined 20 °. 散射器520若以超过45°的角度A安装，经过散射器520且在第二测定部500 测定的激光光束12的输出能量有可能会减少。 In terms of scattering than 520 A mounting angle of 45 °, passing through the diffuser 520 and it is possible in the output energy of the laser beam 500 measured by the second measurement unit 12 is reduced.  激光输出能量的调整： 以下，对本发明所提供的激光输出装置实时调整激光输出能量的过程加以说明。  adjusting the laser output energy is:  Hereinafter, the laser output device of the present invention provides real-time adjustment of output energy of the laser process will be described.  激光输出调整装置的使用者可在控制部600的数据输入部(无图示)上，输入将要照射到基板20上的激光光束10的输出值。  User device may adjust the laser output to the data input unit (not shown) of the control unit 600, the input to the output value of the laser beam irradiated to the substrate 20 on 10. 在激光部100上生成并照射与使用者输入的输出值一致的激光光束10。 Generating the laser irradiation part 100 and the user input coincides with the output value of the laser beam 10.  在激光光束10照射到光学部200之前，可由第一测定部400对输出能量进行测定。 Before  In the laser beam 10 is irradiated to the optical unit 200, the first measuring section 400 may output energy was measured. 这时，若由第一测定部测定的激光光束11的输出能量小于使用者输入的激光光束10的输出能量，即没有生成与在激光光束100上设定的激光光束的输出能量相当的激光光速， 进而可确定激光部100出现了问题。 At this time, if the output energy of the laser beam measured by the first measuring portion 11 is smaller than the laser beam 10 output energy input by the user, i.e., does not generate the laser beam on the laser beam 100 set laser output energy corresponding to the speed of light and further the laser unit 100 may determine there is a problem. 因此，控制部600对第一测定部400上所测定的激光光束11的输出能量与预先设定(使用者输入的）激光光束10的输出能量进行比较后，若激光光束11的输出能量小于激光光束10的输出能量，在控制部600的显不部(无图不）显不激光部100存在异常的同时，提高在激光部100生成的激光光束10的输出能量，以调整至第一测定部400上测定的激光光束11的输出能量与预先设定的激光光束10的输出能量一致。 Thus, the control unit 600 on the output energy of the laser beam 400 measured by the first measurement unit 11 after the laser beam with a predetermined output power (user input) 10 compares the output energy of the laser beam when the laser 11 is less than output energy beam 10, while no significant abnormality in section 600 of the control unit (FIG no no) laser portion 100 is not significant, increase in the output energy of the laser beam generated by the laser unit 10 is 100 to adjust to the first measurement section the output energy of the laser beam 11 is measured with the laser beam 400 on a predetermined uniform output energy 10. 一方面，若进一步设有第一射束分离器410，激光光束10的输出能量的1%至2%会反射到第一测定部400上，因此，控制部600应考虑这一点，再做运算。 In one aspect, if further provided with a first beam splitter 410, the output energy of the laser beam 10 is 1 to 2% will be reflected on the first measuring section 400, therefore, the control unit 600 should take this into account, do arithmetic .  举一例说明，使用者输入的是激光光束10输出100J的能量，但在第一测定部400 上测定的是激光光束11只具备90J的能量，控制部600在显示部(无图示）上显示激光部100存在异常的同时，向激光部100传送信号，使激光光束10输出IlOJ的能量，并进行调整使第一测定部400上测定的激光光束11具备100J的能量。  give one example, the user input is the output 10 of the laser beam energy of 100J, but measured in the first measuring section 400 is provided with the laser beam 11 the energy of 90J, the display unit 600 (not shown control unit on the display) while there is an abnormality of the laser unit 100, 100 transmits a signal to the laser unit, the laser beam 10 IlOJ energy output, and adjust the laser beam 11 having the energy of 100J measured in the first measurement section 400.  接下来，经过光学部200的激光光束10在通过加工部300照射至基板20之前，通过第二测定部500对输出能量进行测定。  Next, the optical portion 200 by laser beam 10 prior to processing by the irradiation unit 300 to the substrate 20, measured by the second measuring section 500 output energy. 这时，如果在第二测定部500上测定的激光光束12的输出能量小于使用者所输入的激光光束10，则认为是激光光束10在经过光学部200 时输出能量减少，可确定光学部200内部的激光光束路径出现了问题。 At this time, if the output energy of the laser beam on the measurement of the second measurement unit 500 is smaller than the laser beam 12 input by the user 10, the laser beam 10 is considered to be when passing through the optical unit 200 outputs the energy reduction, the optical portion 200 may be determined the laser beam path inside there is a problem. 即控制部600接收第一测定部400和第二测定部500的信号，当在第一测定器400上测定的激光光束11的输出能量与预先设定的激光光束10的输出能量一致，而第二测定部500上测定的激光光束12 的输出能量小于预先设定的激光光束10的输出能量时，应是激光部100不存在异常，而光学部200有异常，因此，在控制部600的显示部(无图示）上显示光学部200存在异常的同时，提高在激光部100生成的激光光束10的输出能量，并调整至在第二测定器500上测定的激光光束12的输出能量与预先设定的激光光束10的输出能量一致。 I.e., control unit 600 receives the signal from the first measurement and the second measurement portion 400 of portion 500, when the same output energy of the laser beam measured in the first measurement device 400 and the laser beam 11 is preset energy 10, while the first measuring the output energy of the laser beam 500 on the two measuring portion 12 is less than the output energy of the laser beam 10 is set in advance, the laser portion 100 should be no abnormality exists, and the optical portion 200 is abnormal, and therefore, the display control unit 600 there is an abnormality of the optical portion 200 on the display unit (not shown) while increasing the output energy of the laser beam 100 generated by the laser unit 10, and adjusted to the laser beam in a second measuring device 500 measures the output energy of advance 12 consistent output of the laser beam 10 set energy. 另外，若进一步设有第二射束分离器510，因激光光束10的输出能量中仅有1%至2%反射到第二测定部500 上，控制部600需考虑这一点再做运算。 Further, when further provided with a second beam splitter 510, due to the output energy of the laser beam 10 is only 1-2% is reflected onto the second measuring section 500, the control unit 600 to consider that do arithmetic.  举一例说明，使用者输入的是激光光束10输出100J的能量，但在第一测定部400 上测定的是激光光束11具备100J的能量，而第二测定部500上测定的激光光束12只具备90J的能量，则控制部600在显示部(无图示）上显示激光部100无异常而光学部200有异常的同时，向激光部100传送信号，使激光光束10输出IlOJ的能量，从而调整至第二测定部500上测定的激光光束12具备100J的能量。  give one example, the user input is the output 10 of the laser beam energy of 100J, but measured in the first measuring section 400 is provided with the laser beam 11 100J of energy, measured on the second measurement section 500 of the laser beam 90J 12 includes energy, the control unit 600 display unit 100 of the laser 200 without abnormal abnormal while the optical portion 100 transmits a signal to the laser unit, the laser beam 10 IlOJ energy output on a display unit (not shown) , to adjust to the laser beam 500 measured on the second measurement unit 12 includes 100J of energy.  如上所述，本发明在使用激光的工艺上，可实时测定激光输出能量，使所期望的激光光束输出能量始终保持一致，且更加容易地确定出导致问题发生的激光装置组成部分， 并自动调整激光光束的输出能量，有效加强工艺的可靠性和稳定性。  As described above, in the process of the present invention using a laser, the laser output energy can be determined in real time, so that a desired output power of the laser beam is always consistent, and easier to determine the part of the laser device causing the problem occurs, and automatically adjust the energy output of the laser beam, effective to enhance the reliability and stability of the process.
