Creative Problem-Solving QC Story Based on Systematic Innovation TRIZ

In this study, a ＂creative problem-solving quality control story (CPS-QC story)＂ has been proposed to improve the traditional quality control process. By combining traditional quality control processes and systematic innovation (TRIZ), the concepts of problem solving, innovation tools and methodologies of TRIZ are integrated with the quality control (QC) story tomitigate the lack of problem-solving techniques intraditional QC stories. TRIZ, whichis the core of the CPS-QC story, provides systematic and logical procedures for solving problems. In an actual case study, a mask company in Taiwan uses the CPS-QC story to improve the environmental control systems of mask exposure machines. The level of quality of the improvement is equivalent to the level of quality in a traditional program,whereas the cost and delivery of the improvement is only one-third of the cost and delivery in a traditional program. The results of the study indicate that the CPS-QC story will be beneficial to the photomask industry.
