Rule-based root cause and alias analysis for semiconductor manufacturing
The present invention includes a computing system determining a best alias rule in a semiconductor manufacturing process. The computing system obtains an original rule and candidate alias rules based on sampled data from the semiconductor manufacturing process. The computing system compares the original rule to the candidate alias rules. The computing system ranks the candidate alias rules according to the comparison. The computing system filters the ranked candidate alias rules. A user selects one rule among the filtered candidate alias rules based on knowledge of the semiconductor manufacturing process.
