TXRF-V310
TXRF Spectrometer with Integrated VPD
High-speed metal contamination mapping
Highest sensitivity with VPD
Total reflection X-ray fluorescence (TXRF) analysis can gauge contamination in all fab processes, including cleaning, litho, etch, ashing, films, etc. The TXRF-V310 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-V310 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.
TXRF-V310 Overview
Integrated vapor phase decomposition (VPD) capability enables automatic VPD preparation of one wafer while a TXRF measurement is made on another wafer for the highest sensitivity and high throughput. VPD-TXRF eliminates the operator variability that may occur with ICP-MS, and VPD-TXRF can be completely controlled via factory automation. VPD recovery from selected areas, including the bevel area, is available.
Detection Limit of typical elements (LLD）
| Detection limit LLD (E10 atoms/cm²) | Al | Fe | Ni | Cu |
| TXRF | 25 | 0.10 | 0.10 | 0.15 |
| VPD-TXRF | 0.1 | 0.001 | 0.001 | 0.002 |
Measurement time: 1000 sec
Options
- 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.
- ZEE-TXRF capability overcomes the historical 15 mm edge exclusion of original TXRF designs, enabling measurements to be made with zero edge exclusion.
- BAC-TXRF capability enables fully-automated front-side and back-side TXRF measurements of 300 mm wafers with non-contacting wafer flipping.
