Abstract:
1. An ultraviolet (UV) curing chamber for curing a dielectric material disposed on a substrate, comprising: a body defining a process region where the substrate is supported; a lid coupled to a top of the body that covers and seals a top of the process region; a housing coupled to the lid and disposed above the process region; a first UV bulb within the housing, wherein a first spectral distribution of the first UV bulb is selected for curing the dielectric material; and a second UV bulb having a second spectral distribution different from the first spectral distribution and selected to generate ozone, wherein the first UV bulb is adapted to provide light that is focused on the substrate while the dielectric material is being cured and the second UV bulb provides, relative to the first UV bulb, light that is directed to the entire process region.
