The QUALI-DOSE®: A System for Automatic Chemical Replenishment System

ECI Technology’s dosing experience of more than 15 years enables the QUALI-DOSE® systems to provide the most novel and comprehensive solutions for handling chemistries in existing Advanced Packaging applications.

The QUALI-DOSE system combines with QUALI-FILL® analyzers from ECI Technology to create a comprehensive online chemical management system—the most robust tool available for facilitating stringent chemical process control.

The QUALI-DOSE system uses smart, versatile algorithms and modes to make up, replenish, or bleed and feed the tank. Powered by quick, efficient dosing, the QUALI-DOSE systems generate no waste and avoid the need for regular maintenance.

Thanks to a system that can offer precise dosing with verification of all the critical components, users can enjoy an unparalleled level of convenience and reliability for running their plating process.

Key Features

  • Flexible dosing options are available based on:
    • Wafer count
    • Analysis results
    • Tank level
    • Amp/minute
    • Concentration levels of target or other components
    • Time-based
  • All crucial components can be dosed:
    • DI water
    • Inorganics
    • Organics
    • Feed and bleed (optional)
    • Virgin makeup solution (VMS)
  • Automatic standard generation (ASG)*
    • Avoids frequent chemical handling and mixing
    • Avoids the need to buy high cost standard
    • Minimizes CoO, labor and maintenance
  • Automatic validation—positive feedback with confirmation of each delivery
  • Works in compliance with the industry safety standards: CE SEMI and S2/S8
  • Supports multiple tanks, plating tools, and chemistries
  • Manual mode for any component
