01-03-2005
12-01-2013
Suppliers recognizing the importance of impurity content of gases in the manufacture of semiconductors, responded by introducing products with improved analytical characterization, notably for trace impurities. The following criteria was considered when determining the defined analytical method: Ease of Use; Accuracy; Maintenance; Precision; Sensitivity; Versatility; Reliability; and Availability of Equipment. Specification is specific to Hydrogen (H2), in Cylinders 99.9995% Quality - used in the processing and manufacture of semiconductors etc. Gas complying with the specifications will commonly contain more of the major component than the minimum permissible limit or contain less of an impurity (or several impurities) than the SEMI C3 maximum permissible limit.
