Uncompromising Quality
From raw material sourcing to finished substrate delivery, AXT maintains rigorous quality standards that meet the exacting requirements of the global semiconductor industry.
Quality Philosophy
Quality is foundational to everything AXT produces. Compound semiconductor substrates demand exceptional crystalline perfection, surface quality, and dimensional accuracy — tolerances measured in atomic layers. Our quality management systems are designed to ensure consistency and reliability across every wafer we ship, supported by advanced metrology equipment, statistical process control, and ongoing investment in employee training.
Internationally Recognized
Quality Management Systems
Automotive Quality Management
These certifications reflect our commitment to systematic quality control, continuous improvement, and customer satisfaction across all product lines and manufacturing sites.
Quality Assurance
Raw Material Qualification
Incoming materials — including those from our vertically integrated supply chain — are tested to verify purity, composition, and conformance to specification before entering production.
Crystal Growth Monitoring
Our proprietary VGF crystal growth process incorporates real-time monitoring and control systems to ensure consistent crystal quality, low defect density, and uniform electrical and optical properties.
Wafer Inspection and Testing
Every substrate undergoes rigorous inspection and characterization, including surface quality and flatness measurement, crystallographic orientation verification, electrical property characterization, and visual and automated defect inspection.
Traceability
Full lot traceability from raw material through finished product enables rapid root cause analysis and continuous process improvement.
Continuous Improvement
AXT is committed to continuous improvement across all quality dimensions. We regularly review process performance data, customer feedback, and industry benchmarks to identify opportunities to raise our standards and deliver greater value.
