Surface contamination metrology
Measure elemental contamination at discrete points or with full wafer maps
TXRF analysis can gauge contamination in all fab processes, including cleaning, litho, etch, ashing, films, etc. The TXRF 3760 can measure elements from Na through U with a single-target, 3-beam X-ray system and a liquid nitrogen-free detector system.
The TXRF 3760 includes Rigaku's patented XYθ sample stage system, an in-vacuum wafer robotic transfer system, and new user-friendly windows software. All of these contribute to higher throughput, higher accuracy and precision, and easy routine operation.
Optional Sweeping TXRF software enables mapping of the contaminant distribution over the wafer surface to identify "hot spots" that can be automatically re-measured at higher precision. Optional ZEE-TXRF capability overcomes the historical 15 mm edge exclusion of original TXRF designs, enabling measurements to be made with zero edge exclusion.
