台灣近幾年來政府一直大力推動「兩兆雙星」產業發展,在2010年光電產業合計產值規模已達新台幣2.2兆元。未來國內業者皆全力研發與製造,以配合政府的既定政策來達到應有的目標;在光電面板TFT-LCD(Thin-Film Transistor–Liquid Crystal Display)產業中,各面板大廠都積極在製程技術、垂直整合、品質控管與擴廠增產,來達到更低的成本、更好的利潤,使其更有競爭優勢。
本文以TFT-LCD製程上探討LCD 半成品-CF(Color Filter)彩色濾光片製程 感光性間隔材PS(Photo Spacer)製程的品質特性最佳化之研究,因Photo Spacer製程品質水準一直無法達到穩定之規格中心值,因此本論文研究以田口方法中的直交表及變異數分析方法找出控制因子、水準、最佳參數組合及調整因子後以二階段最佳化來克服Photo Spacer製程品質特性膜厚、關鍵尺寸(Critical Dimension)之變異,達到降低Photo Spacer製程在生產過程中因品質特性不穩定而產生的品質異常成品,以提昇製程能力及良率及降低不必要之調整時間。
運用上述最佳參數在生產線驗證,改善Photo Spacer製程能力指標PS Top Side C.D.改善前 Cp=1.19 ,Cpk=0.43,改善後Cp=2.01, Cpk=1.81。PS Bottom Side C.D. 改善前 Cp=1.12,Cpk=0.98,改善後Cp=1.37,Cpk=1.31。PS Thickness (Hm) 改善前 Cp=1.02,Cpk=0.47,改善後Cp=1.02,Cpk=0.98。
For the past years, the government has been exerting great efforts to set the “Two Trillion Twin Stars” industry development into action; in 2006, the Optoelectronics Industry has reached an output value scope of NT$220,000,000,000.00 in total. The future local industries are exerting all efforts in research and manufacturing, to cooperate with the government’s established strategy in order to achieve the deserved target;in the optoelectronics panel TFT-LCD industry, each panel manufacturers are active on the manufacturing technology, vertical integration, quality control, expansion and production increase,, to achieve lower capital, greater profit and larger competition advantage.
This paper aims to improvement on quality characteristic of Color Filter manufacturing process, the PS (Photo Spacer) process to perform analysis and research. The Taguchi Method by ANOVA and Orthogonal array was used perform the experiment, to find the key factor, standard level, most ideal parameter group and adjustment factor to overcome Photo Spacer process variation of quality characteristic in order to decreasing out of specification production , and increasing the manufacturing capability and efficiency.
With the application of the above-mentioned ideal parameters on the production line for testing and verification, the original process capability of PS Top C.D. Cp=1.19,Cpk=0.43 .Then, after using the adjustment factor, the process capability of PS Top C.D. has reached Cp=2.01,Cpk=1.81, Bottom C.D. before improvement : Cp=1.12,Cpk=0.98,after improvement : Cp=1.37,Cpk=1.31, PS Hm before improvement : Cp=1.02,Cpk=0.47,after improvement : Cp=1.02,Cpk=0.98.
