Data Analysis for Yield Improvement • The ideal goal of the semiconductor manufacturing processes is to make each individual integrated circuit perform to specification • However, physical defects induced during processing and variation in processing causes some individual integrated circuits to fail to perform to specification • The ratio of individual integrated circuits that perform to … As a result, every step in the manufacturing process needs to be completed in less time while maintaining a high level of control and quality. The database design is massively scalable from a few gigabytes of data to terabytes. Process monitoring and profile analysis are crucial in detecting various abnormal events in semiconductor manufacturing, which consists of highly complex, interrelated, and lengthy wafer fabrication processes for yield enhancement and quality control. In modern process of yield management in semiconductor manufacturing throughput yield loss is typically very low as most of the stages are automated and there is very less chance of human errors. After repeated analysis of causes for yield loss in the wafer fabrication process, it is found out that the causes can be categorized into following categories as shown in the diagram below. Scan diagnosis leverages existing design-for-test structures in the design and is based on automatic test pattern generation (ATPG) technology. Semiconductor yield improvement with scan diagnosis.
