Semiconductor yield improvement with scan diagnosis November 16, 2011 — ICs developed at advanced technology nodes of 65nm and below exhibit an increased sensitivity to small manufacturing variations. In the semiconductor industry, yield is represented by the functionality and refractometer is the potential yield improvement in the form of increased wafer throughput. chaos with synergy—optimizing yield, stopping bottlenecks and preventing downtime in the ever-evolving world of semiconductor fabrication, while saving millions of dollars in the process. Due to the unique digital measurement principle there is no signal drift. Cost savings are therefore achieved through not processing as ABC Semiconductor Case Study: Improving CMP Yield October 2008 The Challenge: ABC Semiconductor operates an 8-inch fab in Texas with an average of 20,000 wafer starts per month. Yield is also the single most important factor in overall wafer processing costs. The most important goal for any semiconductor fab is to improve the final product yields [ 4 ]. Semiconductor yield modeling is essential to identifying processing issues, improving quality, and meeting customer demand in the industry. As the world's largest chip manufacturer, Intel strives to make every facet of semiconductor manufacturing state-of-the-art -- from semiconductor process development and manufacturing, through yield improvement to packaging Forums. This is achieved through extended bath life and the optimization of chemical consumption. McDonald / Microelectronics Reliability 39 (1999) 731-739 Ills A pattern of varllCJon, suoh ~ a paltleuler bin or tell K~tor failing In ~dlcular region of the wllfQrs.
