    摘要: An ultraviolet (UV) cure chamber enables curing a dielectric material disposed on a substrate and in situ cleaning thereof. A tandem process chamber provides two separate and adjacent process regions defined by a body covered with a lid having windows aligned respectively above each process region. One or more UV bulbs per process region that are covered by housings coupled to the lid emit UV light directed through the windows onto substrates located within the process regions. The UV bulbs can be an array of light emitting diodes or bulbs utilizing a source such as microwave or radio frequency. The UV light can be pulsed during a cure process. Using oxygen radical/ozone generated remotely and/or in-situ accomplishes cleaning of the chamber. Use of lamp arrays, relative motion of the substrate and lamp head, and real-time modification of lamp reflector shape and/or position can enhance uniformity of substrate illumination.

    摘要: The present invention generally relates to methods of controlling UV lamp output to increase irradiance uniformity. The methods generally include determining a baseline irradiance within a chamber, determining the relative irradiance on a substrate corresponding to a first lamp and a second lamp, and determining correction or compensation factors based on the relative irradiances and the baseline irradiance. The lamps are then adjusted via closed loop control using the correction or compensation factors to individually adjust the lamps to the desired output. The lamps may optionally be adjusted to equal irradiances prior to adjusting the lamps to the desired output. The closed loop control ensures process uniformity from substrate to substrate. The irradiance measurement and the correction or compensation factors allow for adjustment of lamp set points due to chamber component degradation, chamber component replacement, or chamber cleaning.
