Abstract
This work deals with the localized epitaxial growth of SiC on (100) diamond substrate using the Vapour-Liquid-Solid (VLS) transport. An epitaxial relationship of grown SiC with the seed was succesfully achieved when inserting a silicidation step before the VLS growth. This silicidation consists in the formation of a SiC intermediate layer on the diamond substrate by solid-state reaction with a silicon layer deposited at 1000 or 1350 °C. On the 1350°C formed SiC buffer layer, p-doped 3C-SiC(100) islands elongated in the <110> directions were obtained after VLS growth. For the 1000°C buffer layer, the SiC deposit after VLS growth is much denser but mostly polycrystalline. Interfacial reactivity and diffusion are considered to explain the obtained results.
