We investigate the processes of heteroboundary formation during epitaxial growth. Theoretical analysis and computer simulation of elementary processes of the crystal surface growth by molecular-beam epitaxy (MBE) are carried out. Time evolution equations for 2D islands and "holes" on a surface during growth and its interruption are obtained. The function of 2D island size distribution is found to keep the "memory" of its initial shape during MBE. A program for computer stimulation (by Monte-Carlo method) of island formation, growth and coalescence in the epitaxial growth of the vicinal surfaces close to (100) has been devised, having regard to anisotropy of adatom diffusion and directionality of chemical bonds.
