发明名称 Reduction of entrance and exit marks left by a substrate-processing meniscus
摘要 A proximity head for generating and maintaining a meniscus for processing a substrate is described. The proximity head includes a plurality of meniscus nozzles formed on a face of the proximity head, the nozzles being configured to supply liquid to the meniscus, a plurality of vacuum ports formed on the face of the proximity head, the vacuum ports being arranged to completely surround the plurality of meniscus nozzles, and a plurality of gas nozzles formed on the face of the proximity head, the gas nozzles at least partially surrounding the vacuum ports. The proximity head further includes means for reducing a size and frequency of entrance and/or exit marks at a leading edge and a trailing edge on the substrate by aiding and encouraging liquid from the meniscus to evacuate a gap between the substrate and the carrier.
