The TXRF-450 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 15mm edge exclusion of original TXRF designs, enabling measurements to be made with zero edge exclusion.
Optional BAC-TXRF capability enables fully-automated front-side and back-side TXRF measurements of 450mm wafers with non-contacting wafer flipping.
- Quick contamination inspection for semiconductor processes
- Accepts 450 mm and 300 mm wafers
- Wide range of analytical elements (Na~U)
- Light-element sensitivity (for Na, Mg, and Al)
- Single target 3-beam method and XYθ stage are unique to Rigaku, enabling highly accurate ultra trace analysis over the entire wafer surface
- Import measurement coordinates from defect inspection tools for follow-up analysis
