六標準差法應用在改善彩色濾光片之破片
The six sigma approach in improving broken ratio during the color filter processes
摘要
近年來於顯示器(Display)產業中之竸爭激烈，當中以薄膜電晶體液晶平面顯示器(Thin Film Transistor-Liquid Crystal Display)為最。在TFT-LCD之零組件中以彩色濾光片(Color Filter)為成本比重較高者，其成本約佔TFT-LCD材料成本比率30-40%，故彩色濾光片之生產品質將大為影響TFT-LCD產品的品質與成本。而本研究運用六標準差專案手法的DMAIC流程步驟，進行彩色濾光片關鍵製程的改善。首先找出關鍵破片特性值(Define)，衡量量測系統之準確性(Accuracy)，歸納出影響製程的關鍵因子，再利用實驗設計的方法進行實驗測試，找出最佳的機台製程參數組合(Analyze)，進行最佳參數製程能力的驗證，以降低製程不良率 (Improve)，並將最佳參數標準化列為管制項目(Control)。 以DMAIC六標準差專案管理的流程進行改善，其結果顯示彩色濾光片的關鍵製程有明顯改善，且最佳條件組合使破片降低，以達到品質和製程能力提升，且使製程更穩定。

六標準差法並列摘要
In recent years, due to the intense competition in the display industry, the Thin Film Transistor-Liquid Crystal Display is the most. The cost of the Color Filter in TFT-LCD components is the highest, and the cost is about 30~40% of TFT-LCD material, so the quality of Color Filter will fully affect the cost and quality of TFT-LCD product. This research use the practices of Six Sigma project DMAIC process steps to improve key process of Color Filter. First, to find out the characteristic values in glass broken, and to measure the accuracy of measurement system. Summarized the key factor of Process, and use the method of experimental design to do experiment. To find out the best parameter combination of the process, and to improve the best factor of process ability, and to reduce fail rate. Finally, Standardization of the best factor is the key control item. Using Six Sigma project DMAIC process steps to improve process can make the key process of Color filter much better. The best factor combination can make glass scrap rate lower, and achieve high quality and process ability.
