Beyond Lithography Tools: Extreme Measurement and High-Precision Environmental Control Support the Stable Operation of China’s Semiconductor Equipment
Release time:
2026-04-21
Jice’s ultra-high-precision environmental control systems support chip manufacturing and enhance the stability of high-end equipment.
While public discourse is constantly abuzz with the question of whether a single lithography machine can serve as a “chokepoint,” China’s semiconductor industry has long since moved beyond isolated breakthroughs in individual pieces of equipment; the real path to breakthrough lies in a sustained, marathon-like effort to strengthen the entire industrial value chain—from design and EDA tools to process technology, materials, manufacturing, and verification. Only when every link in the chain fits together precisely and collaborates seamlessly can the industry truly develop self-sustaining, “blood-producing” capabilities. And in this invisible battle of systems, Jice High-Precision Environmental Control Product Series is emerging as a critical enabler for the stable operation of high-end equipment and for solidifying the industry’s closed-loop ecosystem, demonstrating through its unparalleled precision at the sub-millimeter level the core principle that “chip manufacturing is not about isolated breakthroughs—it is about systemic symbiosis.”
I. Chip manufacturing is a precision system that tolerates absolutely no deviation.
The public often simplifies the chip industry’s predicament as “lacking a single lithography machine,” but it is easy to overlook this: no matter how advanced the equipment, without an ultra-stable microenvironment to support it, its full performance cannot be realized. Core semiconductor tools such as lithography machines, interferometers, bonding equipment, and metrology systems each impose extremely stringent environmental requirements—temperature, humidity, cleanliness, micro-vibration control, and magnetic shielding. Even the slightest deviation in any of these parameters can be magnified at the nanoscale, thereby affecting yield, product quality, and the stable implementation of manufacturing processes.
II. Ultra-precise ±0.002°C millikelvin-level environmental control, enabling high-end equipment to perform reliably
High-Precision Environmental Control System UPECS: Precise Control of the Entire Microenvironment
The system delivers 24-hour, zone-wide temperature stability of ±0.002°C (±2 mK), humidity control within ±0.1% RH, and cleanliness to ISO Class 1—outperforming the industry-standard ±0.01°C specification. It features a vertical unidirectional airflow design optimized through CFD airflow simulation to effectively minimize eddy currents and stagnant zones. Paired with multi-stage temperature-control patent technology and localized air-bath modules (ABM), it precisely targets and covers equipment’s heat-generating areas. Comprehensive 100% HEPA/ULPA filtration further reduces particulate contamination at the source, creating a highly stable, clean, and interference-free working environment ideal for critical processes such as lithography, bonding, and metrology.
High-Precision Chiller: Equipment Temperature-Controlled Cooling
Leveraging our proprietary high-precision temperature-control technology, the outlet water temperature stability can reach as high as ±0.002°C, accommodating a wide operating temperature range of 5–35°C. Equipped with a dedicated high-precision PID algorithm and a precision data-acquisition module, the system delivers rapid temperature-response and minimal fluctuations, effectively mitigating process and equipment-performance deviations caused by localized overcooling or overheating, thereby ensuring 24-hour uninterrupted and stable operation.
High-Precision Gas Temperature Controller ACU: Precise Adjustment of Process Gas Temperature
Specifically designed for process gases such as compressed air and nitrogen, this solution delivers temperature control accuracy of ±0.01°C, enabling precise gas temperature regulation and minimizing the impact of gas temperature differentials on process stability and instrument measurement accuracy. It supports custom non-standard configurations to meet diverse flow and pressure requirements, playing a critical regulatory role in the gas delivery stages of semiconductor manufacturing processes.
III. Jice Helps the Chinese Chip Industry Grow Steadily
Adapt equipment to facilitate process implementation.
Precisely match the environmental parameters for high-end equipment such as lithography machines, interferometers, and bonders, striving to address the critical challenge of “equipment delivered but processes not yet optimized,” thereby enabling core equipment to fully realize its design performance, accelerating process integration, and steadily improving yield.
Support iteration and drive long-term development
Our comprehensive, non-standard customization capabilities can be tailored to meet the specific, personalized requirements of diverse processes, equipment, and application scenarios. Combined with automated data recording and traceability analytics, these capabilities provide robust data support for process optimization, equipment upgrades, and customer validation.
From making individual components “usable” to ensuring the entire industrial chain is “easy to use, reliably operational, and sustainably viable,” China’s chip industry has never relied on a single “surprise strike.” Instead, it has been built step by step through the relentless technological deep-dive, meticulous product refinement, and seamless system integration achieved by countless core supporting enterprises like Jice—each contributing to solidifying the foundations of industrial development and driving the steady progress of China’s semiconductor sector.
