| dc.description.abstract | 本研究以液晶製程中半成品耗損個案，利用六標準差專案管理的方式以DMAIC為架構進行專案改善，進行製程參數改善。利用SIPOC圖與特性要因圖找出產品品質發生異常的品質特性。收集數據並加以分析找出關鍵零組件或製程參數改善。最後比較專案前後的成果。專案流程可作為相關業界實行六標準差專案的範例。
本研究係採用質性及部分生產數據的量性研究方式，研究個案公司的液晶生產製程，其研究結果可適用範圍:
TFT-LCD面板液晶製造商。
液晶或性質（流程）相似化學品製造業。
液晶單體的成品配調製程。

| dc.description.abstract | This research is a case study which focuses on Ullage Reduction in the manufacturing process of Liquid Crystal by six sigma methodology.
Ullage is the Semi-Finished Goods（SFG）generated along with LC mixture production process. 1568 Kg, 2.6% of the total yield, Ullage was turned out in 2008; total 72.46 Kg of Ullage was scrapped for 2007 and 2008.
Ullage quantity from 2009/12 to 2010/04 was reduced to 0.57%, 78% of Ullage was saved, after the last Ullage improvement item implemented in 2009/11. And 136,806 Euro of financial benefit is expected in 2010.
Six Sigma has been proven both theoretically and practically to be one of the most fundamental method in manufacture process improvement. In this case, the project team improves the manufacturing process through DMAIC stages, and analyzes the critical factors and sources with relevant statistical tools. The methodology here is to experiment on the products quality and Ullage generation in the manufacturing process first, then find the countermeasures via experiment and ＂pilot run＂ process.
This study can be referred in 3 areas for six sigma related projects:
Liquid Crystal manufacturer.
Chemicals which produced with the process similar to Liquid Crystal in this study.
Process of ＂Single＂ material for Liquid Crystal.
