1. An apparatus comprising:
- a conditioning device configured to condition a substrate on a support surface;
a float device configured to provide an air bed above the support surface, wherein the float device is configured to float the substrate on the air bed during conditioning of the substrate;
a displacing device configured to displace the substrate, during the conditioning, from one conditioning position to one or more other conditioning positions;
a pattern generating device having an emissive portion configured to produce a patterned beam; and
a projection system configured to project the patterned beam onto a target portion of the conditioned substrate.

Abstract
An apparatus, method, and system is provided to condition a substrate. The apparatus can include a substrate handler, an array of diodes, and a projection system. The substrate handler can include a conditioning device, a float device, and a displacing device. The array of diodes can be configured to provide a patterned radiation beam, where the projection system projects the patterned radiation beam onto a target portion of a conditioned substrate.
