    摘要: A hollow graphite susceptor for supporting semiconductor substrates during processing in epitaxial reactor systems. The susceptor has reduced wall thickness to provide lower thermal mass for rapid heating and high wafer throughput. Early failure of this thin-walled susceptor is avoided by providing a raised reinforcing boss on its interior surface in alignment with each recess on the exterior surface.

    摘要: A susceptor carrying semiconductor wafers for processing is suspended from a compliant attachment at its upper end and is lowered into a reaction chamber for processing. At the completion of processing, the susceptor is withdrawn vertically to permit a robot to unload the processed wafers and load unprocessed wafers. In order to fix the position of the susceptor during the loading operations, a support carriage is moved into position to engage the lower end of the susceptor. Noxious and corrosive chloride vapors are simultaneously withdrawn from the reaction chamber by a vacuum line attached to the support carriage.
