SEDana was designed by test engineers for test engineers. Since its introduction in 2003, it has been widely accepted throughout the semiconductor industry as best in class for desktop test data analysis. Teradyne recommends it for their applications engineers worldwide.
Test and product engineers can perform the following types of analyses:
- Analysis of production data for test program optimization for yield, etc.
- Test limit guard banding
- Device characterization
- Correlation
- Gage R&R for equipment qualification and release to production
Key features SEDana delivers are:
File Handling: SEDana can work with both STDF as well as .csv formats.
Flexible Filtering: Users can select data sets by pass/fail, bin numbers, outliers, sites, and more.
Reusable Settings: Speed up your analysis by defining your own analysis settings.
Powerful Tables: SEDana allows you to view raw datalogs as well as clearly tabularized results of common statistic metrics. Capability metrics like Cp & Cpk, ANOVA tables as well as Repeatability and Reproducibility tables are readily available.
Powerful Graphics: All data can be visualized in clear graphics designed for the test engineer. Histograms, Pareto charts, trend charts, wafer maps, and 3D wafer maps are all available.
Gage R&R: SEDana includes capabilities to perform full gage repeatability and reproducibility studies. Correlations between testers, load boards, sites, etc. can be easily performed.
Scripting: With its powerful scripting engine SEDana can automate tedious recurring tasks.
Reports: Users may export analysis results in PDF or HTML formats.
A complete Help Manual is included, of course.
