International Standard
71.040.40 Chemical analysis
ISO 14706:2014 specifies a TXRF method for the measurement of the atomic surface density of elemental contamination on chemomechanically polished or epitaxial silicon wafer surfaces. The method is applicable to the following: elements of atomic number from 16 (S) to 92 (U); contamination elements with atomic surface densities from 1 × 1010 atoms/cm2 to 1 × 1014 atoms/cm2; contamination elements with atomic surface densities from 5 × 108 atoms/cm2 to 5 × 1012 atoms/cm2 using a VPD (vapour-phase decomposition) specimen preparation method.
