Process Particles Suspensions
Process Particles™ Suspensions are used as particle material standards. They represent real-world contaminant particles encountered in semiconductor device fabrication processing. Deposition of these particles on wafers and reticles enables characterization of the material-dependent response of a surface inspection system when accurate particle size or particle sphericity are of secondary importance. They consist of broad size distributions of irregularly shaped solid particles suspended in ultra-pure water (UPW). Each bottle contains a suspension volume of 100 mL.
