CS-100F1 Series

Fiber Optic Type Chemical Solution Concentration Monitor

An inline, real-time optical fiber-based chemical concentration monitor that enables measurements of chemicals used in semiconductor manufacturing processes such as cleaning and etching.

Inline real-time measurements can be obtained. A single concentration monitor is capable of simultaneously measuring up to four types (chemicals or ranges), making it suitable for measurements in single wafer cleaning.

Multi-monitoring
Measurements of up to four different substances (chemicals or ranges) are possible with a single concentration monitor.

Short measurement cycles and fast response time
Supports concentration management for 300mm processes with a measurement cycle of approximately 3 seconds. Precise concentration management for both multi-bath and single-bath/sheet-type cleaning equipment are supported.

One of two types can be chosen
The option is available to choose between two types: the inline cell type, which is directly integrated into the main piping and prioritizes real-time concentration tracking, or the cell unit type, which emphasizes stability and allows for feedback control using monitor outputs.
