To cope with the high level standard and to struggle for the market, the panel plants all over the world strive for the market by utilizing diversified technologies such as TFT-LED, LTPS, OLED, AHVA, and Multi-Domain Vertical Alignment (MVA). Nevertheless, whether these technologies are able to improve yields and qualities, or enhance profits, are still the greatest concerns for each panel plant. The research is based upon the issue of automatic clean stocker particle, and the analysis of this problem is constructed within the techniques of define, measure, analyze, improve, and control in Lean Six Sigma. When the products of panel plants become diversified, old automatic clean stockers (STK) may produce particles and eventually affect the products themselves; the research is attempting to find out the optimal strategy through the design of experiment (DOE). Conclusively, the results reveal that the particles of automatic clean stocker declines from 0.1 particle per hour to 0.005 particle per hour after utilizing the Lean Six Sigma; additionally, by using Lean Six Sigma, the quality of TFT-LCD, LTPS and OLED are also improved, and the estimated ameliorative beneficial results are saved for near 1.2 million New Taiwan Dollar of cost of production. The research confirms that the Lean Six Sigma effective can ameliorate the problem of automatic clean stocker particle. Key Words: Lean Six Sigma、, DMAIC, Clean Stocker, Particle , TFT-LCD
