Claim:
1. A substrate handling apparatus for handling a flexible substrate, the substrate handling apparatus comprising: a substrate feeding device to feed the flexible substrate towards an exposure area for exposing the substrate to a beam of radiation; a substrate receiving device to receive the flexible substrate from the exposure area; a substrate stabilization device to maintain, at least in the exposure area, the flexible substrate substantially flat at an exposure height and/or tilt, the substrate stabilization device configured to create an essentially unidirectional flow of fluid that is located between a surface of the flexible substrate and a surface of the substrate stabilization device and that extends for a majority of the exposure area; and a control system configured to enable substantially contactless stabilization of the flexible substrate at least in the exposure area during a time of movement of the substrate relative to and across the substrate stabilization device.
