I. Electron-beam lithography equipment: the core enabler of micro- and nanomanufacturing

Electron-beam lithography equipment is a core tool for nanoscale micro‑ and nano‑fabrication. It uses a focused, high‑energy electron beam to directly pattern fine features on photoresist without the need for a mask, offering high resolution and flexible patterning capabilities. Widely employed in advanced semiconductor process R&D, quantum devices, photonic chips, and the production of high‑end photomasks, it plays a pivotal role in direct‑write of nanoscale circuit patterns, process validation, and small‑batch customized manufacturing, serving as an essential platform for breakthroughs in cutting‑edge fabrication technologies.

II. The Extreme Demands of Electron-Beam Lithography Equipment: Why High-Precision Environmental Control Is Essential

The core precision of electron-beam lithography is extremely sensitive to environmental fluctuations; standard cleanrooms cannot meet its requirements for stable operation, making high‑precision environmental control systems an essential component. Variations in temperature and humidity, particulate contamination, and external vibrations can all disrupt electron‑beam transmission and focusing, degrading exposure accuracy and yield. Consequently, electron-beam lithography equipment must operate under stringent controls for temperature, humidity, cleanliness, and vibration, necessitating a dedicated, high‑precision environmental control system to establish a device‑level microenvironment.

III. Precise Adaptation: The Core Advantages of Jice’s Ultra-Precision Environmental Control System, UPECS

UPECS, the high-precision environmental control system independently developed by Jice (Nanjing) Technology Co., Ltd., is custom‑designed for electron-beam lithography tools. It transcends the limitations of conventional cleanrooms by delivering precise, equipment‑level microenvironment control, fully meeting the stringent requirements of such systems and ensuring reliable nanoscale process accuracy. Addressing the core environmental needs of electron-beam exposure equipment, UPECS achieves benchmark‑level performance: temperature stability as tight as ±0.002°C, humidity stability up to ±0.1%RH, cleanliness levels reaching ISO Class 1, and operating noise no greater than 45 dB. The system supports non‑standard customization, enabling precise alignment with all environmental control specifications of the equipment, while effectively suppressing thermal drift, minimizing particulate contamination, and isolating external vibrations—thereby safeguarding exposure precision and ensuring stable equipment operation. Furthermore, UPECS is built to serve a wide range of application scenarios, offering tailored solutions. Its modular, embedded architecture allows individual functional modules to be configured on demand.

The nanoscale processing precision of electron-beam lithography equipment hinges on the stable, controllable management of every environmental parameter; a high‑precision environmental control system serves as a critical enabler for reliable operation and breakthroughs in accuracy. The Jice High‑Precision Environmental Control System, UPECS, with its well‑defined core parameters, cutting‑edge technologies, and scenario‑specific customization capabilities, precisely meets the stringent environmental requirements of electron-beam lithography tools. Starting with device‑level microenvironment regulation, it provides dependable environmental support for advanced semiconductor process R&D and manufacturing, helping the industry push beyond conventional precision limits and driving the high‑quality development of the high‑end micro‑ and nano‑fabrication sector.
