Abstract:
1. An apparatus for curing a plurality of wafers, the apparatus comprising: a chamber housing having a plurality of stationary semiconductor processing stations, wherein every one of the semiconductor processing stations is associated with a different, non-overlapping UV exposure area located sequentially along a nominally circular path; a plurality of wafer supports, a plurality of ultraviolet (UV) light sources, each of which is associated with one and only one of the UV exposure areas, wherein each UV exposure area is configured to be illuminated by one and only one UV light source of the plurality of UV light sources when the UV light sources are powered, and at least one of the UV light sources includes a cold mirror that is configured to reflect light from the at least one of the UV light sources onto the corresponding UV exposure area; a rotational mechanism with an axis of rotation, the rotational mechanism configured to move the wafer supports along the nominally circular path.
