The Metal-Organic Chemical Vapor Deposition (MOCVD) process is widely used in the manufacture of LEDs, optical devices and other components. Liquid and solid precursors are delivered to the reaction chamber by controlling the temperature, pressure and the carrier gas flow rate (bubbling method). The in-line IR-300 Series measures and reports the precursor concentration in real time giving the user the following benefits:
Optimise process control to produce more high-grade devices
Improve device yield and reduce scrap
Improve reproducibility
Know when a bubbler will require exchanging
Extend MTTA
Reduce unplanned interventions
Reduce valuable precursor waste
Real-time monitoring
Fast response and excellent repeatability allow real time tracking of changes in vapor concentration
Multi-calibration Curve Function (Optional)
Allows for concentration measurement of up to 3 chemicals or ranges
Multi-display Function
The multi-display function on the top of the IR-300 unit gives the user onsite checking capability of concentration monitoring and precursor supply line status
Communications Function
Connectivity through DeviceNet™, RS485 and analog communications
Simple, Compact Design
With a face-to-face size of 124 mm, the unit’s compact and mount-orientation-free design allows for easy integration
A high optical intensity and long-life light source combined with high-speed signal processing enables the IR-300 Series to achieve faster, more repeatable responses to changes in precursor concentration. These features give the user a true understanding of the actual process though real-time inline concentration measurement.
