As the core pillar of high-end manufacturing, the semiconductor industry relies on clean environments as the lifeline of product quality. Even minuscule airborne particles can trigger abnormal chip performance and lower production yields, imposing extremely stringent standards for cleanliness monitoring in manufacturing workshops. Recently, Shaanxi Yuanjie Semiconductor Technology Co., Ltd. (“Yuanjie Semiconductor”) officially purchased the KQET-5108LM Laser Particle Counter from Suzhou Kangqi Environmental Technology Co., Ltd. (“Kangqi Environmental”). The professional monitoring equipment reinforces cleanroom supervision within its semiconductor production lines, enabling precise detection to drive product quality upgrades.

A high-tech enterprise focused on the R&D, design and manufacturing of high-speed semiconductor chips, Yuanjie Semiconductor has specialized in indium phosphide laser chips since its establishment in 2013. Its full product portfolio ranges from 2.5G to 50G devices, widely deployed in fiber access networks, 4G/5G mobile communication infrastructure, data centers and other critical sectors. Backed by cutting-edge technology and stable performance, the company holds a leading position across the industry. Guided by its mission of delivering technologically advanced, high-quality optoelectronic semiconductor chips, Yuanjie Semiconductor maintains stringent production standards with a particular focus on building controlled clean manufacturing environments. The procurement of Kangqi Environmental’s KQET-5108LM Laser Particle Counter stands as tangible proof of its rigorous product quality control standards.

The KQET-5108LM Laser Particle Counter selected by Yuanjie Semiconductor is a high-performance testing instrument engineered exclusively for cleanroom monitoring, whose outstanding performance fully meets the exacting requirements of the semiconductor sector. Centered on light scattering technology, the device adopts photoelectric sensing to accurately detect and count airborne particles by size. With a sampling flow rate of 28.3 L/min, it delivers vastly superior detection precision and efficiency compared to traditional low-flow particle counters, perfectly matching the demand for high-accuracy cleanliness monitoring in semiconductor fabs.

Beyond core performance, the KQET-5108LM boasts multiple tailored advantages for semiconductor manufacturing: Equipped with high-precision sensors that deliver accurate counting compliant with JJF1190-2008, it continuously tracks particle counts at 0.5 μm and 5.0 μm, with expandable support for six particle size channels to fully cover all cleanliness monitoring demands of semiconductor production. A 2.4-inch intelligent touchscreen enables intuitive human-machine interaction and real-time data display, alongside audio-visual alarm functions that alert operators promptly when particle concentrations exceed preset thresholds to contain contamination risks before they escalate. Furthermore, the device supports RS485 communication and the Modbus RTU protocol to enable intelligent IoT connectivity and remote startup. It can also connect to external sensors for temperature, humidity and wind speed, creating a comprehensive cleanroom monitoring system that furnishes objective data to support Yuanjie Semiconductor’s production management.

After deployment, the KQET-5108LM Laser Particle Counter has delivered remarkable operational benefits and tangible improvements to product quality. More advanced semiconductor process nodes demand stricter cleanliness criteria. For Yuanjie Semiconductor’s high-precision laser chips, tiny dust particles can cause device failure or performance degradation in critical processes including gate oxide layer formation and photolithography patterning. Leveraging its 28.3 L/min high-flow sampling and high-precision detection capabilities, the KQET-5108LM tracks real-time particle fluctuations across the workshop and identifies potential contamination hazards early. This allows operators to rapidly troubleshoot issues and adjust environmental parameters, maintaining consistent, standard-compliant clean conditions throughout production. The equipment effectively reduces defect rates caused by substandard cleanliness, stabilizes chip manufacturing consistency and reliability, and guarantees uniform, premium-quality output.

Meanwhile, the device’s intelligent, user-friendly design has significantly boosted Yuanjie Semiconductor’s operational efficiency. Its built-in data storage retains monitoring records for over one month, with USB export functionality for post-process analysis, review and environmental traceability to inform continuous production optimization. A calibration reminder function alerts staff to scheduled equipment calibration, ensuring long-term data reliability while cutting manual maintenance labor and management overhead for simpler, more efficient cleanroom supervision.

This strategic partnership between Yuanjie Semiconductor and Kangqi Environmental represents a mutually beneficial collaboration built on complementary strengths. Yuanjie Semiconductor draws on its deep expertise in semiconductor chips and unwavering commitment to premium manufacturing, while Kangqi Environmental safeguards semiconductor production with professional cleanroom monitoring instruments. The cooperation not only strengthens Yuanjie Semiconductor’s quality assurance barriers but also sets a valuable industry benchmark for clean production monitoring in the semiconductor sector.

Looking ahead, Yuanjie Semiconductor will uphold its pursuit of manufacturing excellence. Supported by the professional monitoring capabilities of the KQET-5108LM Laser Particle Counter from Kangqi Environmental, the company will continuously optimize production environments, deepen its focus on semiconductor chip development and launch more competitive products. It also aims to deepen ties with high-caliber partners such as Kangqi Environmental to jointly advance high-quality development of the semiconductor industry and fuel the rise of China’s high-end manufacturing sector.
