Manufacturing in TFT-LCD panel seeks a way for yield improvement. However, due to the complex manufacturing process of color filter, the manufacturer usually employs the design of experiments as well as engineering experience for process monitoring and quality control. This study aims to develop a three-stage framework to identify the variables significantly affecting yield in color filter manufacturing. An empirical study of was conducted to validate the proposed framework. That result shows that the proposed framework greatly enhances the effectiveness and efficiency on identifying the key factors for yield improvement in color filter manufacturing and saves the labor resource for trouble-shooting.
