This International Standard 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 5×1012atoms/cm2 using a VPD (vapour-phase decomposition) specimen preparation method (see 3.4).
