Clean Enclosure System Escorts Qianghua Co., Ltd. Lingang Base, building a solid clean line of defense for China's "core" manufacturing

Recently, the Qianghua Co., Ltd. Integrated Circuit Core Equipment New Materials Production Base Project located in the Shanghai Lingang Industrial Zone was successfully completed, marking a crucial step in the process of independent controllability of key domestic semiconductor materials. As the core supplier of the clean workshop for this project, the Metal Clean Enclosure System Overall Solution, with its excellent performance and in-depth customization capabilities, has successfully built a high-standard clean barrier for this high-end semiconductor factory. Its core products, handcrafted panels and clean panels, have played a key role, becoming a solid "clean armor" guarding China's "core" manufacturing.

"Lifeline" of Semiconductor Manufacturing: Extreme Demands on Clean Environment

Integrated circuit manufacturing is hailed as the "jewel in the crown" of modern industry, with its process precision reaching the nanometer level. The stability and control of the clean environment directly determine product yield and core precision. During the chip production process, tiny dust, particles or microbial contamination may lead to wafer scrapping, circuit failure, and huge losses. Therefore, semiconductor clean workshops must not only maintain ISO Class 1-5 ultra-high cleanliness, but also meet strict indicators in dimensions such as constant temperature and humidity, stable pressure difference, antibacterial and dust-proof, fire and heat insulation, and low dust generation rate. This places top industry requirements on the materials, processes, sealing performance and stability of core products of the enclosure system such as clean panels and handcrafted panels.

As a leading enterprise in China's semiconductor quartz component industry and a national-level "Specialized, Refined, Characteristic and Innovative" small giant enterprise, Qianghua Co., Ltd. is deeply engaged in the R&D and production of high-purity quartz material products. Its products are indispensable core consumables for key equipment in the entire chip manufacturing process, serving leading enterprises such as SMIC and NAURA. The newly completed Lingang Base covers an area of 32 mu, with a construction area of about 46,700 square meters and a total investment of 550 million yuan. It focuses on the production of 8-12 inch high-purity and high-precision quartz devices and silicon-based devices. As a major strategic emerging industry project in Shanghai, it undertakes the core mission of independent controllability of key semiconductor materials. The construction of its clean workshop must match the production standards of advanced processes of 28nm and below, posing extremely high challenges to the professionalism and reliability of clean panels and handcrafted panels.

Customized Clean Solution: Core Strength Solves Industry Difficulties

With years of technical accumulation in the clean enclosure field and experience in serving semiconductor projects, the team has deeply participated in the planning and design of the clean workshop of Qianghua Co., Ltd. Lingang Base. Combining the special needs of the semiconductor production scenario, it provides a full-process customized overall solution, with high-quality handcrafted panels and clean panels as the core, covering all categories of products such as clean wall panels, ceilings, steel clean doors, full-body anti-fog observation windows, and sealing and closing systems, realizing "integrated design, integrated production and integrated construction" of the enclosure system.

Top-level Materials, Performance Benchmark: The core adopts double glass magnesium rock wool handcrafted clean panels (i.e., high-end handcrafted panels), which are high-quality products among clean panels. They have the characteristics of Class A fire resistance, high-efficiency antibacterial, low dust generation, acid and alkali corrosion resistance, etc. The core material and panel are compounded by ECCP hot-pressing process, with high adhesion and excellent flatness, effectively inhibiting the generation of particles and ensuring the clean environment from the source; at the same time, they have excellent thermal insulation and sound insulation performance, helping to stably control the temperature and humidity of the workshop and reduce energy consumption.

Precise Sealing, Preventing Contamination: Based on customized clean panels and handcrafted panels, the concave-convex insertion connection + Chinese character aluminum sealing structure is adopted for modular assembly, with tight joints without dead ends. Combined with special sealing strips, it achieves "zero gap" enclosure, effectively blocking the invasion of external dust and microorganisms, and preventing the leakage of internal clean air, ensuring the stable pressure difference of the workshop and meeting the requirements of unidirectional air flow in the semiconductor workshop.

In-depth Customization, Adapting to Scenarios: Aiming at the needs of large span, high cleanliness and high load-bearing of the semiconductor workshop, customized ultra-long specifications of clean panels, handcrafted panels and reinforced keel structures are designed to improve the overall strength and stability; it is equipped with low dew point anti-fog full-body observation windows, which are highly transparent and free of condensation, taking into account production visualization and clean sealing; the steel clean door adopts an integrated molding process, with tight sealing and silent opening and closing, adapting to high-frequency use scenarios.

Efficient Delivery, Controllable Quality: Relying on the automated production lines of the two intelligent manufacturing bases in Shandong and Anhui, the standardized and large-scale production of clean panels, handcrafted panels and other products is realized, ensuring the consistency of delivery cycle and quality; it is equipped with a CNAS national recognized laboratory, and all batches of handcrafted panels, clean panels and other products have passed strict performance tests, complying with the clean standards of the semiconductor industry, providing a solid guarantee for the high-quality landing of the project.

Empowering Industrial Independent Controllability, Co-building the Future of China's "Core"

From design and R&D to production and construction, the team has strictly controlled every detail and promoted the project landing with a "zero defect" standard. Its high-quality handcrafted panels, clean panels and overall enclosure system have performed excellently, and finally successfully completed the construction of the clean workshop enclosure system. All indicators have met or exceeded the design requirements, winning high recognition from Qianghua Co., Ltd. The smooth delivery of this project is not only another benchmark case in the high-end semiconductor clean field, but also demonstrates the major breakthroughs of domestic clean panels, handcrafted panels and clean enclosure systems in core technologies, customization capabilities and quality reliability, breaking the monopoly of overseas brands in the high-end market and helping the upgrading of independent controllability of the semiconductor industry chain.

At present, China's integrated circuit industry is accelerating the breakthrough of key core technologies, striding forward towards high-end processes and independent controllability. As the "infrastructure" of semiconductor manufacturing, the clean enclosure system, among which core products such as clean panels and handcrafted panels are the key links to ensure chip yield and improve production efficiency. In the future, we will continue to deepen the R&D of clean technologies, focus on high-end fields such as semiconductors, biomedicine and precision manufacturing, constantly iterate the performance of clean panels and handcrafted panels, optimize solutions, and empower more semiconductor benchmark projects with more core technologies, better products and more professional services, continuously build a solid clean line of defense for China's "core" manufacturing, and contribute to the high-quality development of China's integrated circuit industry.
