Abstract:
1. A system for curing a workpiece, comprising: a chamber housing; a substrate support in the chamber housing for supporting a workpiece; a radiation source operable to direct radiation onto a workpiece supported on the substrate support in order to cure the workpiece; and a pump liner including a ring-shaped element having a central opening shaped to fit around a periphery of the workpiece, the ring-shaped element having a gas inlet plenum and a gas outlet plenum for receiving a flow of purge gas into a first channel in the ring-shaped element and exhausting the flow of purge gas from a second channel in the ring-shaped element, the pump liner having a plurality of injection slits positioned near the central opening and operable to direct a substantially laminar flow of purge gas across a surface of the workpiece being cured by the radiation, the pump liner further having a plurality of receiving slits positioned near the central opening and opposite the plurality of injection slits operable to receive the flow of gas directed across the wafer, the receiving slits being further operable to receive any species outgassed from the workpiece during the curing process.
