Products Description
MKS Instruments AX8400 0190-26 Ozone Generator

Technical Specifications
Model:AX8400 0190-26 Brand:MKS Instruments Product Type: SEMOZON AX8400 series ultra-clean ozone generator
Module Feature
MKS AX8400 is compact high-concentration ozone generator adopting patented silent discharge cell technology. It converts high purity oxygen feed gas into ozone, requires trace dopant nitrogen, extremely low NOx byproduct. Fully welded all-metal wetted components, low outgassing, integrated ozone concentration monitoring and safety interlock system. Widely used for semiconductor TEOS/Ozone CVD, oxide deposition, photoresist stripping and wafer surface treatment.
Working principle: High purity oxygen passes through discharge cell, silent electrical discharge breaks oxygen molecules and recombines into ozone gas, integrated sensor monitors real-time ozone concentration Onboard components: Ozone discharge cell, gas flow control assembly, concentration detector, control PCB, stainless steel gas manifold, gas inlet/outlet metal fittings, multi-pin power & communication connector
LED indicatorsPower, ready, fault and ozone status LED indicators on front panel
Hardware self-diagnosis
Visual inspection, gas leak tightness test, ozone concentration calibration, interlock function test, gas flow verification
Programming software
MKS SEMOZON configuration software for ozone concentration setpoint, gas recipe setup and fault log reading
Electrical & Process Parameters
Power supply:200-240V AC Feed gas:High purity oxygen with trace nitrogen dopant Wetted material:316L stainless steel Control interface:Analog I/O + serial communication Safety function:Ozone destruct & emergency shut-off interlock
Mechanical & Structure
Mounting:Equipment rack mounting Protection class:IP40
Environmental
Operating temperature:10℃ ~ +40℃ Ambient humidity:5~95% non-condensing Certification:CE, SEMI compliant Status:MKS SEMOZON AX8400 ozone generator
System compatibility
Matched with MKS MFC and Baratron gauge, integrated into semiconductor CVD and wafer cleaning gas delivery system.
Function
AX8400 ozone generator manufactured by MKS Instruments. It produces ultra-high purity ozone on demand for semiconductor thin film process. All welded metal manifold reduces contamination. Discharge cell aging, gas leakage or interlock fault will cause unstable ozone concentration and safety alarm. It is critical reactive gas source for oxide deposition and wafer treatment.
Installation
Follow lockout/tagout safety procedure before installation. Cut off gas and power supply. Mount unit on equipment rack. Connect oxygen inlet and ozone outlet metal gas fittings. Wire AC power and control signal cable. Complete gas leak test, ozone concentration calibration before production startup.
Interface
Metal seal gas inlet and gas outlet fittings, multi-pin connector for AC power, analog and serial communication, status LED indicators on housing of AX8400 0190-26.
Diagnostic
Ozone concentration low: Discharge cell degradation or oxygen feed pressure abnormal. Gas leakage: Fitting loose or manifold weld defect. System fault alarm: Interlock triggered or communication loss. No ozone output: Feed gas shut-off or power failure.
