Semiconductor yield models are traditionally based on the analysis of the “critical area”. It offers a very detailed statistical root cause analysis in just a couple of clicks. Let’s Connect Legal Yield Optimisation. Yield-management software or Semiconductor data-analysis software comes in really handy in these cases; such software is able to collect data from test sites as well as the operation floor, map the data to a standardized format, and then perform complex analysis to find the root-cause of failures and defects. Get more out of your data with enterprise resource planning All of this procedure of semiconductor engineering data analysis can be quite daunting if conducted manually. In this case study approach, predictive failure analytics is used to optimize critical components of integrated circuits and handle massive amounts of data arising from the monitoring and modeling of the manufacturing process. The most important goal for any semiconductor fab is to improve the final product yields [ 4 ]. Also Yield improvement is the most critical goal of all semiconductor operations as it reflects the amount of product that can be sold rela-tive to the amount that is started. yieldHUB combines semiconductor expertise with the latest cloud technologies. This type of categorization does not take into consideration organized yield problems associated with design errors rather it only focusses on the yield loss issues caused by arbitrary events in the manufacturing process. Integrated circuit process control monitoring (PCM) data and wafer yield analyzed by using synchrotron X-ray topographic measurements. yieldHUB helps you to increase yield and reduce scrap. The conflicts or disturbances causing die yield loss can be further categorized in to two types, namely local and global disturbances. at a high mix semiconductor equipment manufacturing facility was the motivation for this project. Effectively selecting the right devices for failure analysis is a challenge. In yield analysis for semiconductor manufacturing it is observed that the primary source that results in loss of yield happens during the wafer fabrication stage, while some of the rest of the loss in yield that appears in later stages can be attributed to the issues related to wafer handling. The data analysis required to monitor and enhance yield is a huge challenge, especially as data volumes grow large and diverse with shrinking technology nodes.
