    • A vertical rapid thermal processing system includes a processing chamber and an elevator structure providing for vertical movement of a workpiece within the processing chamber. The elevator structure includes a workpiece support for supporting the workpiece and an elevator shaft coupled to the workpiece support and extending externally from the processing chamber. An end portion of the elevator shaft, external to the processing chamber, has a selected magnetic polarity. The elevator structure also includes moveable carriage coupled to the shaft to provide vertical movement of the workpiece within the processing chamber. The carriage includes a shaft support having the selected polarity. The shaft support is positioned adjacent the polarized end portion of the elevator shaft such that repulsive magnetic forces maintain a gap between the end portion of the elevator shaft and the shaft support as the shaft support and elevator shaft move vertically along a path of travel.
    • 垂直快速热处理系统包括处理室和提供工件在处理室内的垂直移动的升降机结构。 电梯结构包括用于支撑工件的工件支撑件和联接到工件支撑件并从处理室外部延伸的升降机轴。 电梯井的在处理室外部的端部具有选定的磁极性。 电梯结构还包括联接到轴的可移动的托架,以提供工件在处理室内的垂直移动。 托架包括具有所选极性的轴支撑件。 轴支撑件邻近电梯井的极化端部定位,使得当轴支撑件和电梯井沿行进路径垂直移动时,排斥磁力在电梯井的端部与轴支撑件之间保持间隙。
