半导体制造数据分析的数据工程

Data Engineering for the Analysis of Semiconductor Manufacturing Data

Peter D. Turney

摘要:

我们使用称为Q-YIELD的决策树归纳软件分析了来自几个不同半导体制造厂的制造数据。该软件生成规则,用于预测给定产品何时应该被拒绝。这些规则旨在帮助工艺工程师通过帮助他们发现拒收的原因来提高产品的产量。Q-YIELD的经验告诉我们数据工程的重要性--预处理数据以启用或促进决策树归纳。本文讨论了我们在半导体制造数据方面遇到的一些数据工程问题。本文涉及两大类问题:工程的特征向量表示和工程的目标概念(类)的定义的功能。制造过程数据对特征工程提出了特殊的问题,因为数据具有多个粒度级别(细节,分辨率)。设计目标概念很重要,因为我们专注于了解过去,而不是在机器学习中更常见的关注预测未来。

英文摘要:

We have analyzed manufacturing data from several different semiconductor manufacturing plants, using decision tree induction software called Q-YIELD. The software generates rules for predicting when a given product should be rejected. The rules are intended to help the process engineers improve the yield of the product, by helping them to discover the causes of rejection. Experience with Q-YIELD has taught us the importance of data engineering -- preprocessing the data to enable or facilitate decision tree induction. This paper discusses some of the data engineering problems we have encountered with semiconductor manufacturing data. The paper deals with two broad classes of problems: engineering the features in a feature vector representation and engineering the definition of the target concept (the classes). Manufacturing process data present special problems for feature engineering, since the data have multiple levels of granularity (detail, resolution). Engineering the target concept is important, due to our focus on understanding the past, as opposed to the more common focus in machine learning on predicting the future.
