Shanghai Chengwei Semiconductor Equipment Co., Ltd provide ultra-high purity gas & chemical systems for semiconductors, displays & advanced manufacturing.

SHANGHAI, CHINA, August 27, 2026 /EINPresswire.com/ -- Shanghai Chengwei Semiconductor Equipment Co., Ltd. (CWSC), a newly established provider of critical process system equipment, today announced its formal operations as an integrated supplier of ultra-high purity (UHP) gas and chemical delivery solutions. Founded in September 2025 with a registered capital of 10 million RMB, the company is based in Shanghai’s Songjiang District and operates a state-of-the-art 4,000-square-meter facility. This includes a 2,500-square-meter ultra-clean production area featuring a 500-square-meter Class 100 cleanroom, enabling the highest standards of contamination control.

Driven by its core values of Win-Win, Collaboration, and Innovation, CWSC specializes in the design, manufacturing, and system integration of high-purity fluid and gas delivery equipment. The company serves premium manufacturing sectors that demand strict contamination control and precise chemical dosing, including semiconductors and PCB circuit boards, flat panel displays and LEDs, solar energy and photovoltaics, and optical fibers.

“In modern semiconductor fabs and related high-tech industries, reliable ultra-high purity delivery systems are essential for yield, safety, and process efficiency,” said a company spokesperson. “Our mission is to provide complete, high-performance solutions that eliminate manual handling risks, ensure consistent impurity control, and support continuous, on-demand chemical and gas supply.”

CWSC’s core product portfolio covers three main areas. Chemical Delivery System includes Automatic Chemical Delivery Modules for acids, alkalis, and organic solvents, featuring dual-drum automatic switching, PFA piping, and sub-micron filtration. Additional offerings encompass Chemical Charging Boxes for tanker unloading, high-precision mixing and dilution systems achieving accuracy of ±0.001 percent, specialized 24-hour continuous-circulation Slurry Delivery Systems for CMP processes using magnetic levitation pumps, and Valve Manifold Boxes for safe multi-channel distribution.

In Ultra-High Purity Bulk Gas Delivery Systems, the company supplies Gas Cabinets and Gas Racks equipped with multi-stage safety interlocks, nitrogen and vacuum purging for handling toxic, flammable, and corrosive gases. The portfolio also includes bulk specialty gas systems, high-precision gas mixing systems, and liquid/vapor delivery setups for precursors such as TEOS, TMA, and DEZ. Automation and smart control solutions feature Chemical Management Systems for real-time level tracking, leak detection, and data logging, along with factory-wide gas detection networks with rapid-response alarms and emergency shut-offs. Complementary Gas Scrubber Systems further support exhaust treatment needs.

All critical manufacturing steps—including tube cutting, facing, orbital welding, piping assembly, and system integration—are performed inside cleanrooms to minimize particle contamination. Supported by automated CAD and SolidWorks 3D fluid modeling, CWSC maintains robust monthly production capacities of approximately 60 Gas Cabinets and 120 Valve Manifold Boxes for gas systems, plus 20 Chemical Delivery Modules, 20 slurry systems, and 200 chemical Valve Manifold Boxes.

Stringent quality assurance underpins every shipment. Systems undergo rigorous testing, including pressure holding tests (≤1 percent drop over 24 hours), helium leak tests (≤1.0×10⁻⁹ mbar·L/s), particle counts (≤1 particle at 0.1 µm), and moisture/oxygen increments (≤1 ppb). A four-tier quality management system, covering raw material inspection, first-article confirmation, and functional debugging, combined with a responsive PDCA customer care model, ensures compliance with next-generation semiconductor fabrication standards.

By enabling bulk chemical delivery with pre-distribution filtration, CWSC’s systems help customers reduce production costs, improve process efficiency and yield, decrease chemical spillages, and enhance operational safety. These solutions support key semiconductor processes such as CVD, ALD, etching, cleaning, and CMP, while also serving broader applications in displays, PCBs, and new energy sectors.

As a specialized Chinese supplier focused on domestic advanced manufacturing needs, CWSC is positioned to contribute to the growing demand for reliable, high-purity process infrastructure. The company offers design, manufacturing, retrofitting, and servicing capabilities, inviting industry partners to collaborate on customized UHP delivery solutions.
