SEMI M24 - Specification for Polished Monocrystalline Silicon Premium Wafers
This standard was technically approved by the global Silicon Wafer Committee. This edition was approved for publication by the global Audits & Reviews Subcommittee on November 21, 2006. It was available at www.semi.org in February 2007. Originally published in 1994; previously published November 2005.
This document specifies requirements for virgin silicon premium wafers with nominal diameter from 150–300 mm used for particle counting, metal contamination monitoring, and measuring pattern resolution in the photolithography process in semiconductor manufacturing. The premium wafer has tighter specification values in some specific items for the specific usage, and looser or equal specification values in other items than a prime wafer has.
