Research Abstract

Single crystal silicon carbide (SiC) is one of the potential materials for the precise structures in severe environment, such as X-ray mirrors. But it is difficult to achieve high accuracy by using conventional cutting and/or grinding processes because of its high hardness. We have been applying molecular beam epitaxy (MBE), which is one of the crystal growth techniques in vacuum, to the surface finishing process in atomic level. We were extending this process from homo-epitaxy of silicon on silicon substrate to hetero-epitaxy of SiC on silicon substrate. The motivations of previous studies related to MBE were not the application to machining process but the interest in physical or electric property, thus, MBE has not been established as a surface smoothing process. This study tried to investigate the SiC hetero-epitaxial growth process on Si substrate experimentally, aiming to establish it as a smoothing process. However, the properties of the obtained SiC surface, such as chemical composition and roughness, are not satisfactory. In this study, the proper conditions were investigated to improve the surface properties in hetero-epitaxy of silicon carbide on silicon substrate. The substrate temperature during the process, which strongly affects the epitaxial growth process, was changed between 1023K and 1373K.It is found that the proper substrate temperature, 1073-1173K in this case, improves the roughness up to 1.4 nm Ra while keeping good crystal structure.
