This Standard was technically approved by the global Silicon Wafer Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on February 21, 2012. Available at www.semiviews.org and www.semi.org in April 2012; originally published November 2001; previously published October 2011.


This Guide provides recommendations for specifying measurement systems for geometry and flatness of silicon wafers of the 130, 90, 65, 45, 32 and 22 nm technology generation as anticipated by the International Technology Roadmap for Semiconductors (ITRS) and in the forecasts of the major manufacturers of semiconductor devices. Wafer parameters as defined by SEMI M1, SEMI M8, SEMI M11, SEMI M24, or SEMI M38 are specified by customers of silicon wafer suppliers and are usually part of Certificates of Compliance. Suppliers of silicon wafers and their customers might measure these parameters using equipment provided by different manufacturers of such equipment or using different generations of equipment of one supplier. Agreement on basic features and capability of such measurement systems improves data exchange and interpretation of data as well as procurement of appropriate measurement systems.
