Abstract: A semiconductor processing apparatus includes a reaction chamber (202, 302, 402), a movable susceptor (208, 308, 408, 508, 808), a movement element (210, 310, 810), and a control system (211, 811). The reaction chamber (202, 302, 402) includes a baseplate (212, 312, 412, 512, 812). The baseplate (212, 312, 412, 512, 812) includes an opening (250, 350, 450, 550). The movable susceptor (208, 308, 408, 508, 808) is configured to hold a workpiece (W). The movable element (210, 310, 810) is configured to move a workpiece (W) held on the susceptor (208, 308, 408, 508, 808) towards the opening (250, 350, 450, 550) of the baseplate (212, 312, 412, 512, 812). The control system (211, 811) is configured to space the susceptor (208, 308, 408, 508, 808) from the baseplate (212, 312, 412, 512, 812) by an unsealed gap (216, 316, 416, 516, 816) during processing of a workpiece (W) in the reaction chamber (202, 302, 402). Purge gases may flow through the gap (216, 316, 416, 516, 816) into the reaction chamber (202, 302, 402). Methods of maintaining the gap (216, 316, 416, 516, 816) during processing include calibrating the height of pads (520, 530) and capacitance measurements when the susceptor (208, 308, 408, 508, 808) is spaced from the baseplate (212, 312, 412, 512, 812).
