CMP slurry dispersibility analysis

Particle dispersion analysis in slurry stock solution

For quality control of CMP slurry, we were able to quickly distinguish between OK products with a size of 100 nm or less and coarse particles (NG products) with a size of around a few μm.

Laser diffraction/scattering particle size distribution measuring analyzer Partica LA-960V2

  • Compatible with particle sizes from 10 nm to 5000 μm
  • Guaranteed high accuracy of ±0.6% against NIST traceable standard samples
  • Particle size distribution under high concentration conditions can be measured using a high concentration cell.
