SEMI E146 - Test Method for the Determination of Particulate Contamination from Minienvironments used for Storage and Transport of Silicon Wafers
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 defines a test method for the determination of particulate contamination from minienvironments used for storage and transport of silicon wafers in semiconductor manufacturing.
The particulate contamination performance of a minienvironment used for storage and transport of silicon wafers is measured in terms of the number of added particles within fixed ranges of size on the surface of silicon wafers exposed to those minienvironments under variable storage, transport, or environmental conditions.
Both user and supplier of the minienvironment shall agree upon all important parameters defined in this Test Method; for example,
• the minienvironment used to store and transport the silicon wafers,
• the silicon wafers exposed to the minienvironment,
• the test equipment used for variable storage, transport, or environmental tests of the minienvironment,
• the analytical equipment used for particulate contamination measurements on the surface of the silicon wafers,
• the environmental conditions around the test equipment and the analytical equipment, and
• the statistical evaluation of the particulate contamination measurement results from the analytical equipment.
These definitions ensure that communication between the user and the supplier of the minienvironment takes place on the same level when specifying these parameters.
