METHODS FOR FORMING SINGLE CRYSTAL SILICON INGOTS WITH REDUCED CARBON CONTAMINATION AND SUSCEPTORS FOR USE IN SUCH METHODS

A graphite susceptor for supporting a quartz crucible during a crystal growth process includes a body having an interior surface and a coating deposited onto the interior surface. The interior surface of the body defines a cavity, and the cavity has a size and shape complementary to an outer size an...

Beschreibung
Zusammenfassung:	A graphite susceptor for supporting a quartz crucible during a crystal growth process includes a body having an interior surface and a coating deposited onto the interior surface. The interior surface of the body defines a cavity, and the cavity has a size and shape complementary to an outer size and shape of the crucible. The coating includes boron nitride and a sintering additive. The sintering additive is configured to promote densification of the boron nitride.
