Comptek Solutions

Kontrox™ is Comptek Solutions’ patented advanced passivation technology engineered to overcome native oxidation and surface defect challenges in compound semiconductors. By transforming semiconductor surfaces into a stable native crystalline oxide structure, Kontrox™ eliminates up to 98% of surface defects and creates a robust, contamination-resistant interface that significantly improves device performance and long-term reliability.

Surface and interface defects are among the key limitations in III–V and wide-bandgap semiconductors, where rapid native oxidation generates electrically active defect states that degrade efficiency, stability, and yield. Kontrox™ directly addresses this bottleneck through precise surface preparation and controlled nanoengineering of the native oxide, enabling semiconductor interfaces with unprecedented stability and electronic quality.

Kontrox™ delivers substantial performance benefits across both optoelectronic and power devices. In microLEDs, it has demonstrated over 250% efficiency improvement and up to 90× lower power consumption, while enabling dramatic chip-size reduction without sacrificing performance. This allows manufacturers to place significantly more devices per wafer, cutting material usage, cost, and environmental impact.

For GaN power devices, Kontrox™ provides a clear advantage over conventional thin-film passivation (ALD or PECVD) by delivering a stable native oxide interface that improves channel stability and electron transport, enabling higher efficiency, lower losses, improved reliability, and increased manufacturing yield.

Kontrox™ is compatible with a wide range of III–V materials, including GaAs, GaN, InGaAs, GaSb, InP, InAs, and InSb, and supports applications spanning lasers, microLEDs, IR detectors, VCSELs, RF devices, and power electronics. The technology is designed to complement or replace conventional passivation approaches with a lower total cost of ownership, improved scalability, and superior device stability.

Kontrox™ enables a new level of performance, sustainability, and manufacturing economics for next-generation compound semiconductor devices.

Kontrox™ LASE 16 is the first market-ready turnkey system specifically designed and optimized for the passivation of edge-emitting laser bar facets. It combines advanced plasma surface conditioning with Comptek Solutions’ patented Kontrox™ nanoengineering to deliver stable, high-performance facet protection in a fully integrated production tool.

Key capabilities include:

• High-precision plasma surface preparation to remove contaminants and activate the facet for optimal passivation
• Kontrox™ native crystalline oxide formation, creating a stable, contamination-resistant barrier with long-term reliability
• Integrated multi-process flow combining cleaning, passivation, and sealing in a single ultra-clean vacuum environment
• High throughput for volume manufacturing, supporting up to ~1,800 laser bars per day with multi-stacking jigs
• Excellent facet stability, enabling greater flexibility in downstream mirror coating and processing
• Compact UHV chamber and PLC-based automation for stable, reproducible, and production-ready operation
• Custom process recipes, developed using advanced characterization tailored to each customer’s device design

Kontrox™ LASE 16 is designed for seamless integration into industrial production lines, delivering significantly improved manufacturing yield, enhanced laser performance, and reduced total process cost compared with conventional passivation approaches.

By replacing conventional thin-film passivation with a stable native oxide barrier, Kontrox™ LASE 16 enables long-term optical stability, higher device reliability, and improved lifetime performance, making it ideal for high-power laser diodes, VCSELs, and other demanding III–V laser applications.

Kontrox™ LASE 16 provides premium industrial-grade passivation in a cost-effective, scalable platform—setting a new benchmark for laser facet protection.
