Abstract

To meet the semiconductor industry's demands for accurate measurements, we have developed a method to characterize the nonlinear response of 193 nm excimer laser detectors. This system is complimentary to our other excimer laser power and energy calibration services and provides a quantitative measurement of a detector's response over a large energy/power range. Detectors are typically used over a larger energy/power range than that covered by a single calibration point. Measurement uncertainty can be introduced if the nonlinear response is not quantified. Range discontinuity, e.g., due to change in detector amplification, can also introduce additional measurement uncertainty. Experimental results revealed nonlinearity of some UV detectors as high as 8%.
