Retrieving and Integrating IC (Integrated Circuits) Fabrication Data from Dissimilar Databases.

摘要

Factory personnel need to access data from many aspects of the fabrication environment. Many IC fabrication facilities store manufacturing data in distributed, heterogeneous database networks. Retrieval and integration of data can be a cumbersome task due to this configuration. The ideal solution to these problems is to standardize a data model, storing the manufacturing data in a single database. However, since such a standardization is not likely to occur in the near future, a more immediate solution is needed. This article discusses a system addressing these problems: DRIFS - A Data Retrieval Interface for Integrated Circuit Fabrication Systems. A uniform query interface and data model is defined for heterogeneous, distributed fabrication databases. A DRIFS prototype is described and evaluated. (RH)
