A hybrid induction-resistive heating system for processing semiconductor substrates includes a single induction coil surrounding a cylindrical susceptor and at least two resistive heaters disposed within the susceptor. The susceptor provides electromagnetic shielding to isolate the coil from the resistive heaters. A controller independently regulates heater output in response to temperature measurements within the heater to equalize temperatures across multiple zones of the susceptor. In operation, the coil provides rapid bulk heating while the resistive heaters supply localized spot heat, resulting in uniform thermal conditions along the length of the heater. The system achieves temperatures up to 2300° C. suitable for heat treating silicon carbide substrates in batch processes.
