Front End CMP Slurries - Overview

Available Front End CMP Slurries

• FSL1600C
  • Next-generation Poly Open Polish (POP) slurry for gate last/ replacement metal gate (RMG) integrations for Logic & Memory
  • Baseline of non-selective removal of nitride, oxide, and good stop on poly-silicon
  • All 3 dielectrics’ rates and selectivities are tunable
  • High purity colloidal silica and ultra-pure chemicals for ultra-low defectivity
  • Concentrated formulation for attractive cost of ownership
• FSL1531C
  • Poly-silicon slurry with stop on various dielectrics and metals
  • Very high and intermediate poly-silicon rates possible. High Ti/ TiN liner rates
  • TMAH-free EHS benign chemistry & high purity colloidal silica deliver ultra-low defectivity
  • Highly dilutable slurry offerings for attractive cost of ownership
• FSL1700C 
  • Silicon Oxide slurry with stop on silicon nitride
