Calculation of Depth Distribution Functions for Characteristic and for Continuous Radiation,n 5% when compared with those given by the model of Pouchou and Pichoir. The calculation of depth distribution curves for continuous radiation reveals that the differences between characteristic and continuous curves are larger than commonly expected. These differences depend on the overvoltage and on the atomic number.

Automatic Analysis of Soft X-Ray Emission Spectra Obtained by EPMA,the SRIP-method is applied in the iterative procedure until convergence is attained. While observing the residuals, the next peak is added to the previous model and the procedure continues. The results are illustrated by examples of oxygen soft X-ray emission spectra deconvolution for periclase, korund, and quartz.

It is demonstrated that when these effects are properly accounted for and a good matrix correction program in conjunction with consistent mass absorption coefficients is used good quantitative results can be obtained.

In the present paper first simulations are discussed with the aim of comparing backscattered electron and secondary electron profiles of wall and trench structures. Special attention is given to the influence of the shape of the target surface topography on the electron backscattering and secondary emission.
