TSDF
Time-Series Degradation Data Format for Semiconductor Reliability Data
...It aims to take a potentially large amount of reliability data and put it into a small number of files that are human readable. TSDF does this by separating metadata from raw data. With this separation, it is easy for a user to view or search through a set of TSDF files to get information needed to put the data in context (process, lot and wafer info, device types, failure mechanism, etc.)
Based on this data format, software tools such as conversion programs, database management tools, and data analysis tools will be developed and distributed to the user community. ...
