NOTICE: This Standard or Safety Guideline has an Inactive Status because the conditions to maintain Current Status have not been met. Inactive Standards or Safety Guidelines are available from SEMI and continue to be valid for use.


This Standard specifies the cassettes used to transport and store 300 mm wafers in an IC manufacturing facility. This includes both manual and auto-transport use as well as high-speed extraction of the wafers in processing equipment.

This Standard is intended to set an appropriate level of specification that places minimal limits on innovation while ensuring modularity and interchangeability at all mechanical interfaces. Most of the requirements given in this Specification are in the form of maximum or minimum dimensions with very few required surfaces. Only the mechanical interfaces for cassettes are specified; no materials requirements or micro-contamination limits are given. However, this Standard has been written so that both metal and injection-molded plastic cassettes can be manufactured in conformance with it.
