WAFER SURFACE CONTAMINATION
COMPACT SPECTROMETER FOR UP TO 200 mm WAFERS
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 3800e can measure elements from S through U with a single-target, dual-beam X-ray system, and a new liquid nitrogen-free detector system.
The TXRF 3800e includes the Rigaku patent pending X-Y-θ 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" — out to zero edge exclusion.
These features are housed in a new, compact, and efficient design. Access for all maintenance work is through the front, and rear panels, so other cleanroom equipment may be placed next to the TXRF 3800e. This represents a significant savings expense for clean-room space.
