To achive fluorescent SiC with a thickness of approximately 200 µm, the feasibility of achieving growth-rate maintenance while stabilizing the B supply by RF coil position control was investigated. By suppressing the sublimation rate of BN powder through RF coil position control, a useful guideline for stabilizing the B supply during long-term growth was obtained. On the other hand, a decrease in the growth rate was identified as a new challenge. Further stabilization of the B supply during long-term growth while maintaining a high growth rate is required for the achievement of thick-film fluorescent SiC.
