Crystal site location of dopants in semiconductors using a 100-keV electron probe

Abstract
The channeling effect on electron induced characteristic x‐ray emission has been used to study the site occupancy of As in submicron regions of Si (3×1019 As atoms cm3). We report here the first absolute intensity measurements of the crystallographic orientation dependence of characteristic x‐ray production by kilovolt electrons in order to determine quantitatively the crystal site occupancy of an impurity.
