Optimization of the Silicidation and Growth Processes for 3C-SiC Heteroepitaxy on Diamond Substrate

Article Preview

Abstract:

This work reports on the CVD heteroepitaxial growth of 3C-SiC layers on diamond (100) substrates. To obtain good layer quality, the growth procedure involves a “silicidation” step consisting in depositing a silicon layer by CVD on the diamond substrate, in order to elaborate a very thin SiC buffer layer. 3C-SiC growth is then performed on this SiC seeding layer. Silicidation and growth parameters have been studied in order to improve the quality and the morphology uniformity of the heteroepitaxial layer. The study points out the role of liquid silicon during the growth process.
