Numerous books and articles provide the basic concepts and benefits of the six sigma method. The challenges and realities in implementing the six sigma method successfully are immense. The purpose of this research is to reduce the percent defective of Polyimide by six sigma management. The most popular approach of six sigma management is definition (D), measurement (M), analysis (A), improve (I) and control (C). Several tools including SIPOC diagram, cause and effect diagram, failure mode and effects analysis (FMEA) are utilized in this project. The results show that the average defect counts of the Polyimide reduced from 20.3 pieces to 4.2 pieces per maintain cycle. Thus, the internal failure cost of rework decreased 72%. The total saving is 1,812,480 per year. In conclusion, DMAIC is an effective way for continuous improvement.
