This standard was technically approved by the global Silicon Wafer Committee. This edition was approved for publication by the global Audits & Reviews Subcommittee on April 30, 2010. Initially available at www.semi.org in June 2010.
The developmental wafers covered by this specification are intended for use in research and development of process and metrology equipment and fabrication processes required for manufacturing high-density integrated circuits on 450 mm diameter single crystal silicon wafers. They can also be used to establish the techniques and metrology necessary to support a dimensional specification for 450 mm diameter circuit-quality (prime) wafers.
This specification covers dimensional and crystallographic orientation requirements for 450 mm diameter, polished single crystal silicon wafers needed in development. This document should be superseded by dimensional specification and technology-specific guidelines for circuit-quality wafers.
A complete purchase specification requires that additional physical properties be specified along with test methods for determining their magnitude. If a test instrument is not available, the acceptance criteria should be agreed upon between supplier and customer.
This specification also contains guidance to assist equipment manufacturers and others to specify wafers for use in developing selected process equipment and unit processes.
The specification for 450 mm diameter mechanical handling wafers used in development of 450 mm semiconductor equipment such as 450 mm wafers carriers, load ports, Automated Materials Handling System (AMHS), and robotics has already been published as SEMI M74.
This specification is not intended to be a product wafer specification.
For referee purposes, SI (System International, commonly called metric) units shall be used.
