Release time:
2025-11-06
The application of this system provides localized, high-cleanliness environmental solutions for China's advanced manufacturing industries, such as semiconductors and microelectronics, thereby supporting the ongoing advancement of our country's drive toward independent development of cutting-edge equipment.
Jice (Nanjing) Technology Co., Ltd., whose core technological achievement is the independently developed
High-Precision Environmental Control Equipment
, it has steadily achieved ISO Class 1 cleanroom standards. As one of the domestic enterprises mastering cleanroom environment control technologies at this level, it provides core technical support for the long-term environmental protection of critical equipment in China's high-end manufacturing sector.
The ISO Class 1 cleanliness standard is an internationally recognized, exceptionally high-grade of cleanliness, requiring no more than 10 particles with a diameter ≥0.1 μm per cubic meter of air. It imposes stringent requirements on core technical parameters such as airflow control, filtration accuracy, and precise temperature regulation across different zones—making it widely used in cutting-edge equipment fields like semiconductor lithography machines and coating/developing systems, where environmental cleanliness is critically sensitive. At Extreme Measurement (Nanjing), we ensure the long-term, stable operation of this rigorous standard through multi-dimensional technological innovation.
In its airflow control design, the system employs a vertical unidirectional flow architecture, ensuring that clean airflows evenly cover the controlled area. At the same time, it incorporates computational fluid dynamics (CFD) airflow simulation technology to refine and optimize the airflow distribution pathways. This approach effectively eliminates the vortex dead zones commonly found in conventional systems, thereby minimizing particle retention risks at the source and guaranteeing the uniformity and stability of the cleanroom environment.
To meet the personalized needs of high-end equipment, Jice (Nanjing) has further implemented precise, customized key temperature-control zones within critical devices such as lithography machines and coating/developing systems. By integrating tailored temperature-control algorithms with advanced high-precision sensing technology, the company has achieved temperature control accuracy as fine as ±2 mK (±0.002°C) in these vital areas. This not only satisfies the stringent ISO Class 1 cleanliness standards but also ensures stable, consistent temperatures essential for the reliable operation of the equipment’s core components—effectively addressing the industry challenge of simultaneously achieving "ultra-clean" conditions and "high-precision temperature control."
According to the technical head of Jice (Nanjing), the company's high-precision environmental control equipment and clean filtration system have consistently met the ISO Class 1 cleanliness standard, reflecting years of technological expertise accumulated by the enterprise in this field. The system's application provides localized, ultra-clean environment solutions for China's advanced manufacturing industries, such as semiconductors and microelectronics, thereby supporting the ongoing advancement of China's drive toward self-reliant development of high-end equipment. Looking ahead, the company will continue to deepen its R&D efforts, injecting new momentum into the industry's high-quality growth.
