Abstract
The physical and chemical prerequisites of ion implantation and their translation into a Monte Carlo calculation simulating the implantation process of high energy ions (300 keV) are described; calculations are extended to high dose implantation (up to 1×1018 ions cm−2) taking into consideration various effects such as matrix change during implantation, cascade mixing, sputter erosion and relaxation of the target material.
To check the suitability of such calculations for a characterization of implanted samples, the results of the calculations are compared with those obtained experimentally from implanted samples. As an example,P + is implanted into polycrystalline Al at various doses (1⋯10×1017 p + cm−2), and depth profiles are taken by AES/Ar+-sputtering.
The calculated and measured results agree better than 10% for both the depth and the concentration scale.
