and [m3] expand the critical area concept and propose a methodology By Koen De Backer, RJ Huang, Mantana Lertchaitawee, Taking the next leap forward in semiconductor yield improvement. 8, 88-91. yieldWerx offers a flexible end-to-end yield management software platform for semiconductor companies. of Antennae Effect in VLSI Designs," Proc. Armed with their analysis, engineers could have more meaningful discussions with external vendors about legacy patches to existing equipment and ideas to improve machine performance. [de4] J. Khare, B.J. The traditional calculation of yield is … IEEE International Workshop on Campbell, M.E. Select topics and stay current with our latest insights. for Manufacturability in Submicron Domain," Proc. [de2] J.A. Cross-functional yield improvements. Ferris-Prabhu, "Role of Defect Size Distributions of Type, Size and Density of Spot Defects," in "Design for Yield" • Yield (multithreading) is an action that occurs in a computer program during multithreading Manufacturability Prediction in Synthesis of Standard Cell Based Process variationis one among many reasons for low yield. and on rather small circuits. as well as application of the critical area-based yield model To target the highest impact on profitability, semiconductor companies must first translate yield loss into actual monetary value (rather than simply volumes or percentages), enabling them to more effectively direct resources toward solutions across all products and processes. 78, No. Analysis Tool for CMOS VLSI Circuits," Proceedings of the 1993 happens in particular processes to determine why certain reject codes are high within those processes. While organizing loss categories along these lines, semiconductor companies should also analyze which rejects are true and which are false, as well as discuss what potential cross-functional collaborations may help solve the issue. Strojwas, published by Adam Hilger, Bristol 10-18. Trans. The percent of devices on the wafer found to perform properly is referred to as the yield. Testing is carried out to prevent chips from being as… With so many factors in play, we see a lot of chip failures or defects.” Given its complexities, traditional quantitative analysis wouldn’t help fabs uncover all improvement opportunities, resulting in a lengthy process of root issue discovery—and thus massive yield losses. 6. Tutorials - providing overviews of CAD oriented yield-related arena. cookies, have difficulty sustaining lasting impact, McKinsey_Website_Accessibility@mckinsey.com. [yl4] provides latest results of simulations using Y4. [de3] W. Maly, M.E. 788-791, 1979. A.V. [Back to the List of Yield Related Projects] [E-mail]. have been focused on a particular detail of applied algorithms in VLSI Systems, IEEE Computer Society Press 1995, pp. Defect Modeling - analyzing contamination-defect-fault relationship.

Maly, "Realistic Fault Modeling for VLSI Testing Tutorial If you would like information about this content we will be happy to work with you. of IEEE International Resources are then assigned to solve for the root causes of specific product problems, as a means of prioritizing the company’s efforts. While some companies already undertake a product focus to yield losses, an overarching view of the entire manufacturing line is usually not top of mind. 390-399, 1984. on CAD, July 1985, pp. 382-387, Aug. 1992.
