Semiconducting testing is essential to guarantee the quality of products sold to customers. Complex devices require a comprehensive test plan to collect crucial measurement data to evaluate the silicon performance for meeting all the requirements according to specification. This kind of test flow is typically implemented through multiple test insertions of test solution but with higher complexity. Thus, there is an incentive to create a scalable data system for provisioning test data from one insertion to the next one(s) at run-time to drive better test efficiency. One of the main challenges in Data Feed Forward (DFF) systems is to provide unit level traceability to connected test data from various data sources through lot genealogy and exact data association. Once full unit level traceability is realized under the boundary conditions, the DFF data can precisely be streamlined on various platforms of test tools such as wafer prober and Automated Test Equipment (ATE) handler. After the DFF data are collected at a test insertion, the dataset must be verified to confirm no issue of missing or duplicated data. The dataset needs to be checked again upon retrieval from the data sources before consumption at a later test insertion. There must be minimal test time overhead when the DFF data is generated or consumed at run time to avoid any offset of the DFF benefits. Another important aspect of the DFF system is factory automation and standard methodology such that the DFF flow can be executed seamlessly in production without human support or intervention. At the end, the DFF infrastructure must ensure data integrity to provide complete, accurate, clean, and consistent data that is repeatable and reproducible over time. This requires a robust and rigorous validation plan to ascertain DFF capability, manufacturability, and sustainability to support the various business use cases and applications. There are many benefits and impacts by DFF that include better product performance, enhanced process control, package drift analysis and compensation enhancement, temperature curative correction, etc., resulting in new market opportunity and improved test throughput.
