Synchrotron-based total-reflection x-ray fluorescence (SR-TXRF) has been developed as a leading technique for measuring wafer cleanliness. It holds advantages over other techniques in that it is non-destructive and allows mapping of the surface. The highest sensitivity observed thus far is 3 {times} 10{sup 8} atoms/cm{sup 2} ({approx} 3fg) for 1,000 second count time. Several applications of SR-TXRF are presented which take advantage of the energy tunability of the synchrotron source or the mapping capability.
