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.
