Wafer support system

An apparatus for processing a substrate comprises a susceptor for supporting the substrate, an upper heat source spaced above the susceptor, a lower heat source spaced below the susceptor, and a controller. The controller provides power to the heat sources at a selected ratio between the sources. Th...

Beschreibung
Zusammenfassung:	An apparatus for processing a substrate comprises a susceptor for supporting the substrate, an upper heat source spaced above the susceptor, a lower heat source spaced below the susceptor, and a controller. The controller provides power to the heat sources at a selected ratio between the sources. The controller is configured to vary the ratio during a high temperature processing cycle of a substrate to thereby vary the ratio of the heat provided by the heat sources during the cycle.
