Dissolved Carbon Dioxide (DI-CO2) Ultrapure Water Delivery System
Overview
The DI-CO2 is used in single substrate cleaning tools for rinsing steps to prevent ESD effects and/or corrosion by creating UPW (ultrapure water) with precisely defined conductivity. It is a compact system for tool integration, providing conductive DI-CO2 water (Carbon Dioxide) with closed loop controlled conductivity. The conductivity is kept at a constant value under changing flow conditions by control of the CO2 concentration in the DI-CO2 water.
- Closed-loop conductivity control
- Small, compact module for integration
- Low cost of ownership, no CO2 and no UPW consumption at process pauses
- Maximum conductivity at physical limits
- Highest accuracy
- Flow is allowed to change between 0.5 - 90 L/min to keep conductivity stable
