Nowadays, the problems of increasing the effectiveness of the students studying the complex microelectronic processes in the light of a competent approach to education, enhancing the role of self-education and distant learning are urgent. The process and equipment of the single crystal growing by the Czochralski method has been described. The necessity of taking into account the dynamic links in the examination of the control channels has been substantiated. The scheme and formulas, which allow using the theory of random processes for time tracking and quantifying all smooth changes in the diameter of a growing crystal, as well as the interference effect, have been presented. The development tools for virtual laboratory and visualization functions using the multimedia elements and color dynamics have been described. The application of the development environment Excel + VBA, the connection of functions of the Windows operating system API, special data structures, the use of modeling and animation permit to show the crystal and crucible rotation, the crystal growth dynamics, as well as preparatory procedures of the whole process. The developed program can be used in the students’ preparation for work in a real laboratory as well as for distant training.
