Motorola’s Engineering Data Analysis System: 10 Years of Analytical Excellence

In an effort to improve semiconductor product yields, an engineering data analysis application was developed in 1989 for engineers at Motorola’s Advanced Products Research and Development Laboratory (APRDL). This application was called EDAS – the Engineering Data Analysis System. What began as a small text-based tool providing a handful of statistical reports used in one laboratory has grown to a large graphical system providing over 55 different analytical tools, used globally in Motorola’s wafer fabrication plants and final manufacturing sites. The SAS system has been used as the basis of the EDAS system throughout its ten-year history. Whenever SAS Institute releases a new version of the SAS system, EDAS is upgraded to take advantage of those new features. Currently, the Analysis & Reporting Tools team is evaluating SAS version 8 to determine which new features can be utilized in the next major release of EDAS. SAS products discussed in this paper include SAS/AF, QC, GRAPH, STAT, and others. The intended audience is anyone interested in semiconductor data analysis.
