INLINE CONCENTRATION MONITOR provides real-time measurement in critical processes of semiconductor wet chemical applications. The instrument integration to process environments and control systems with industrial standard communication protocols is flexible with stand-alone refractometer setups, as well as optional modular connection units and external displays.

Our semiconductor fab chemical monitor is ideal for a variety of applications, including:

  • Chemical blend checksum of SC-1 and SC-2
  • Hard mask etching with NH3 water mixes
  • Silicon wet etch with 50% KOH
  • Titanium etch with H2SO4:HNO3:H3PO4 mixes
  • Back side poly etch with HF:HNO3 mixtures
  • Post-CMP cleans with various mixtures

Our technology is capable of monitoring a wide range of critical semiconductor chemicals, including but not limited to:

  • Hydrogen peroxide (H2O2)
  • Ammonium hydroxide (NH3 water)
  • Dilute hydrofluoric acid (HF)
  • Phosphoric acid (H3PO4)
