Patent ID: 8137465

Claim:
An apparatus for curing a plurality of wafers, the apparatus comprising: a) a chamber housing; b) one or more wafer supports; c) a plurality of non-overlapping UV exposure areas; d) a plurality of UV light sources, each of which is associated with one and only one of the UV exposure areas, wherein each UV exposure area is illuminated by one and only one UV light source of the plurality of UV light sources; and e) a rotational mechanism configured to: 1) sequentially expose each wafer to each of the plurality of UV light sources, wherein each wafer is uniquely within the associated UV exposure area during exposure to a particular UV light source, 2) concurrently expose multiple wafers to light from separate UV light sources, and 3) concurrently transfer multiple wafers between sequential UV exposure areas, wherein each of the concurrently transferred wafers is transferred from a different UV exposure area than from which any of the other concurrently transferred wafers are transferred, and wherein each of the concurrently transferred wafers is transferred to a different UV exposure area than to which any of the other concurrently transferred wafers are transferred.
