TXRF 310Fab

High-speed metal contamination mapping for up to 300 mm wafers

Measurement of trace elemental surface contamination

Total reflection X-ray fluorescence (TXRF) analysis can gauge contamination in all fab processes, including cleaning, litho, etch, ashing, films, etc. The TXRF 310Fab can measure elements from Na through U with a single-target, 3-beam X-ray system and a liquid nitrogen-free detector system.

TXRF 310Fab system for wafer surface contamination metrology by TXRF

TXRF 310Fab Overview

The TXRF 310Fab includes Rigaku's patented XYθ sample stage system, an in-vacuum wafer robotic transfer system, and new user-friendly windows software. These contribute to higher throughput, 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.

Options

  • 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.
