Jewellok Technology Sets New Benchmark for Semiconductor Purity with Launch of Advanced Chemical VMB Systems

[James Yuan]

SHENZHEN, CHINA  – Shenzhen Jewellok Technology Co., Ltd., a global leader in ultra-high purity (UHP) fluid control, today announced the commercial release of its next-generation Chemical Valve Manifold Box (VMB) Distribution System. This launch marks a pivotal advancement in chemical delivery infrastructure, specifically engineered to support the rigorous yield requirements of 5nm and 3nm semiconductor fabrication nodes.

As global chip manufacturing transitions to increasingly complex architectures, the "last mile" of chemical delivery—the transition from bulk storage to the process tool—has become a critical bottleneck for contamination control. Jewellok’s new VMB solution addresses this by utilizing proprietary 316L electropolished stainless steel components, achieving an internal surface roughness of 5Ra. This mirror-finish prevents the microscopic "trapping" of particles, ensuring that chemicals reach the wafer at parts-per-trillion (ppt) purity levels.

"The integrity of a fab's chemical supply is its lifeblood," said a senior technical director at Jewellok Technology. "Our new VMB system isn't just an enclosure; it is a smart, reactive environment. By combining our high-precision diaphragm valves with real-time PLC monitoring, we provide fab operators with the microscopic control necessary to prevent even a single metallic ion from compromising a production run."

Technological Innovation and Safety Excellence
The Jewellok Chemical VMB system is designed with a "Safety-First" architecture that meets and exceeds international SEMI S2 and SEMI S8 standards. Key technical highlights include:

• Zero-Leak Integrity: Every manifold is helium leak tested to a stringent $1.0 \times 10^{-9}$ atm-cc/sec standard, providing a vacuum-tight seal that protects personnel from hazardous, corrosive, or pyrophoric materials.
• Intelligent Automation: The system features a fully integrated 15-inch HMI touchscreen powered by advanced PLC logic. This allows for automated, multi-step Nitrogen ($N_2$) purging cycles and real-time pressure decay testing, significantly reducing maintenance downtime.
• Redundant Leak Detection: Equipped with high-sensitivity optical and conductivity leak sensors, the system triggers an instantaneous "All-Stop" and isolates the supply line in the event of a breach, preventing cleanroom contamination.
• Modular Scalability: The "Plug-and-Play" stick design allows fabs to expand from 4 to 24 distribution points without the need for extensive facility re-piping, offering unmatched flexibility for evolving production lines.

A Global Solution for High-Tech Industries
While primarily focused on the semiconductor sector, the Jewellok VMB is also optimized for the Photovoltaic (PV) and EV Battery industries. In these sectors, the demand for high-flow, consistent chemical delivery is essential for increasing cell efficiency and battery longevity. Jewellok’s systems are manufactured in state-of-the-art Class 100 cleanrooms, ensuring that every unit is delivered "process-ready" for immediate installation.

With this launch, Jewellok Technology reaffirms its commitment to the global semiconductor supply chain, offering localized technical support and custom engineering services to Tier-1 manufacturers across Asia, Europe, and North America.
