WAFER SUPPORT SYSTEM, WAFER SUPPORT DEVICE, SYSTEM COMPRISING A WAFER AND A WAFER SUPPORT DEVICE AS WELL AS MASK ALIGNER
A wafer support system has a wafer support device and a dicing frame, wherein the wafer support device has a bottom plate and a top plate. The top plate has a support surface for supporting the wafer, and the bottom plate has a maximum diameter being larger than the maximum diameter of the top plate so that the bottom plate forms a repository for the dicing frame. The dicing frame has a plate-like shape defining a center hole, wherein the minimum diameter of the center hole is larger than the maximum diameter of the top plate so that the dicing frame sinks below the upper surface of the wafer and/or the support surface. Further, a wafer support device, a wafer support system and a mask aligner are provided.
EXPOSURE APPARATUS AND METHOD FOR EXPOSURE OF TRANSPARENT SUBSTRATE
An exposure apparatus includes a carrying device and a UV light generation device that irradiate a transparent substrate positioned on the carrying device.

MICROSTRUCTURE PATTERNS
In one aspect, there is provided a method of creating a microstructure pattern on an exterior surface of an aircraft, boat, automobile or other vehicle is disclosed. A layer of photopolymer (44) is applied to the top coat or substrate (43) by nozzles (45). The photopolymer is selectively irradiated to activate its photoinitiator and the unirradiated polymer is removed. The irradiation can be via a mask (49) which does not come into contact with the polymer, or via a beam splitting arrangement (63, 64) or a diffraction grating (71). The pattern can be formed by either leaving the exposed photopolymer in situ, or using the exposed photopolymer to mask the substrate, etching the substrate, and then removing the exposed photopolymer. In another aspect, there is provided a method 1100 comprising the step 1102 of applying a layer of photocurable material to the exterior surface, the step 1104 of irradiating the photocurable material with radiation including a predetermined irradiation intensity profile, and the step 1106 of removing uncured photocurable material to form the microstructure pattern. The radiation initiates curing of the irradiated photocurable material, causing a curing depth profile across the layer of the photocurable material corresponding to the selected intensity pro file.
