Tool Fault Analysis with Decision Tree Induction and Sequence Mining
Abstract:
Tool fault analysis is a common task for process engineers in modern industries to maintain high yields of the final products. Statistical process control is a monitoring method normally adopted by most engineers. Recently, there has been enormous awareness among industrial and manufacturing engineers that intelligent techniques from the data mining and machine learning fields can be applied to discover subtle patterns from the manufacturing process data. In this paper, we present the two data mining techniques, i.e. decision tree induction and sequence mining, to discover frequently occurred patterns of the low performance wafer lots in the semiconductor manufacturing industries. The comparative analysis results of both techniques are presented through experimentation over the standard data set for the purpose of re-experimentation.
