    摘要: A trap system adapted to trap polyimide or other vapors exiting from a process chamber. The vapors are routed from the process chamber through a heated exit line at low pressure and then cooled, resulting in condensation at a selected location. The condensed vapors accumulate in a liquid trap. A method of condensing polymer vapors in vacuum exit lines of process chambers, where the flow which may have vaporized polymer vapor is cooled to enhance condensation at a chosen location. The liquid trap can be emptied and replaced, resulting in the removal of the condensed liquid. The chamber exit lines are protected from condensation build up.

    摘要: A device and method for alignment of substrates on a substrate support, such as a heated chuck. An alignment ring may be placed over the substrate support to maintain placement and alignment during processing, such as plasma processing. The aligned substrate may then be accessed by a robotic arm, as it is in a pre-determined location. Alignment rings of different interior diameters may be used for different substrate sizes. The alignment rings may be inserted onto and removed from the process oven containing the substrate support through the substrate access port, without the need to fully open the process chamber.
