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. M. Karilahti, Neural Net Analysis of Integrated Circuit Yield Dependence on CMOS Process Control Parameters, Microelectronics Reliability 43, 117-121 (2003). Yield is directly correlated to contamination, design margin, process, and equipment errors along with fab operators [ 11 ]. Made by Together Digital. The path forward involves a shift in mind-sets as well as deployment of advanced-analytics solutions. This ensures the maximum yield can be guaranteed and maintained. It is often observed that splitting attributes in the route node do not indicate the hypothesized causes of failure. 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. A Comprehensive Big-Data-Based Monitoring System for Yield Enhancement in Semiconductor Manufacturing Abstract: In this paper, we focus on yield analysis task where engineers identify the cause of failure from wafer failure map patterns and manufacturing histories.
