Classification: CPC H  B  F | IPC B  H

Claim 7:
8. An ultraviolet (UV) curing apparatus for curing a semiconductor wafer, the UV apparatus comprising:
a process chamber in which a semiconductor wafer is loaded for UV curing, said process chamber including a mounting assembly arranged to support the semiconductor wafer within the process chamber; and
a UV light source including at least one UV lamp assembly, said UV lamp assembly comprising:
a UV lamp which emits UV light;
a first reflector arranged proximate to a first side of said UV lamp, said first reflector including a first surface facing said UV lamp from which UV light emitted by said UV lamp is at least partially reflected into the process chamber; and
a UV reflective coating partially coating said first surface of the first reflector;

wherein a plurality of areas of the first surface of the first reflector remain uncoated with the UV reflective coating, the plurality of areas uncoated are located within a first zone encompassing the first surface, and the plurality of areas uncoated are each separated by said UV reflective coating partially coating said first surface of the first reflector.
