Increased tool utilization/reduction in mwbc for UV curing chamber
ActiveUS20070298362A1Avoid collectingHigh emissivitySemiconductor/solid-state device manufacturingCharge manipulationUV curingInjection port
A pump liner is used to direct a laminar flow of purge gas across a workpiece to remove contaminants or species outgassed or otherwise produced by the workpiece during processing. The pump liner can take the form of a ring having a plurality of injection ports, such as slits of a variety of shapes and / or sizes, opposite a plurality of receiving ports in order to provide the laminar flow. The flow of purge gas is sufficient to carry a contaminant or outgassed species from the processing chamber in order to prevent the collection of the contaminants on components of the chamber. The pump liner can be heated, via conduction and irradiation from a radiation source, for example, in order to prevent the condensation of species on the liner. The pump liner also can be anodized or otherwise processed in order to increase the emissivity of the liner.
