A wafer support system comprising a segmented susceptor having top and bottom sections and gas flow passages therethrough. A plurality of spacers projecting from a recess formed in the top section of the susceptor support a wafer in spaced relationship with respect to the recess. A sweep gas is introduced to the bottom section of the segmented susceptor and travels through the gas flow passages to exit in at least one circular array of outlets in the recess and underneath the spaced wafer. The sweep gas travels radially outward between the susceptor and wafer to prevent back-side contamination of the wafer. The gas is delivered through a hollow drive shaft and into a multi-armed susceptor support underneath the susceptor. The support arms conduct the sweep gas from the drive shaft to the gas passages in the segmented susceptor. The gas passages are arranged to heat the sweep gas prior to delivery underneath the wafer.

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.

Abstract:
A method is provided for treating wafers on a low mass support. The method includes mounting a temperature sensor in proximity to the wafer, which is supported on the low mass support, such that the sensor is only loosely thermally coupled to the wafer. A temperature controller is programmed to critically tune the wafer temperature in a temperature ramp, though the controller directly controls the sensor temperature. A wafer treatment, such as epitaxial silicon deposition, is started before the sensor temperature has stabilized. Accordingly, significant time is saved for the treatment process, and wafer throughput improved.
