Features of the surface morphology of CaF2/Si(100) films obtained by solid-phase epitaxy
2016
The dielectric parameters of calcium fluoride films grown on the Si(100) surface by solid-phase epitaxy (group 2) and without it (group 1) are analyzed. It is established experimentally that the deposition mode of CaF2 films immediately after growth of the Si buffer layer at a substrate temperature of 530°C is not suitable for producing high-quality dielectric layers. The use of solid-phase epitaxy at the initial stage of the nucleation of CaF2 layers enables the production of single crystal uniformly thick films with high dielectric properties.
