摘要

日益增長的全球競爭及面對客戶選擇更多元的衝擊下，要在如此競爭激烈又嚴峻的市場中能站有一席，獲得穩定的客源與訂單，唯有卓越產品質以及研究開發新產品，才能使得公司永續經營。為了因應全球環境強大的竸爭，迫使公司需尋求持續改進，藉由消除流程中的報廢之浪費，降低產品生產成本，並且持續改善品質，提升產品競爭力，進而增強企業之競爭力。
本研究以面板線缺陷瑕疵問題點之自動光學檢測能力為議題，並以面板模組維修部門為案例，運用六標準差之觀念及改善手法DMAIC為主軸進行製程專案改善，藉由定義、量測、分析、改善和控制六標準差系統方法，針對自動光學檢測相關硬體設備與參數設定進行改善，並經由實證得知其結果能有效提升線缺陷問題點的檢出率。

Under the impact of increasing global competition and facing more requirements from customers, it is necessary to have excellent product quality and outstanding development of new products to obtain stable customers and orders; therefore, the company may have a position in such a highly competitive and severe market. In order to make the company sustainable and to cope with the strong global environment, the company is forced to seek continuous improvement, to eliminate the waste in the process, to reduce the production cost, to enhance the competitiveness of the product, and thus enhance the enterprise strength.
In this study, a TFT-LCD panel module maintenance department planned to enhance capability of an automatic optical inspection machine to correctly detect the panel line defect problem. The six-sigma methodology and DMAIC improvement process were used to find the root causes and main control factors. The method of the six-sigma system was applied to improve the hardware equipment and to set parameter values of the inspection process. The findings were validated by implementing those values in the shop floor and it showed the detection rate of line defects was effectively improved.
