Abstract
The use of Decision Trees to analyze data is discussed as an approach to solving problems of Yield excursions in semiconductor manufacturing. The relation to equipment commonality is discussed along with some of the pitfalls of incautious use of general probability estimates. The paper introduces a Mixing Diagram to help visualize commonality issues, it introduces work around methods for resolving ambiguities in the commonality, it reviews Decision Trees algorithms, and it ends with a discussion of current limitations of the method along with recommendations for future research.
