HIGH-THROUGHPUT SILICON CARBIDE REACTOR

Methods and systems for growing silicon carbide epitaxial layers are described. In one example, a reactor system with multiple reactor modules may include a heating load/lock chamber and a cooling load/lock chamber. In another example, a reactor may be heated by separate sets of coils inductively he...

Beschreibung
Zusammenfassung:	Methods and systems for growing silicon carbide epitaxial layers are described. In one example, a reactor system with multiple reactor modules may include a heating load/lock chamber and a cooling load/lock chamber. In another example, a reactor may be heated by separate sets of coils inductively heating a susceptor, which heats graphite near one or more wafers. Multiple pyrometers may measure the temperature of the graphite walls at different locations. Based on temperature differences and/or temperature gradients, a temperature controller may adjust power provided to one or more sets of coils. In yet another example, separations between a wafer carrier and a wafer may be adjusted.
