WOFLY Unveils High-Safety Silane Valve Manifold Box (VMB) to Empower Semiconductor and PV Manufacturing

Shenzhen Wofly Technology Co., Ltd. (WOFLY), a premier provider of ultra-high purity gas delivery systems, has officially launched its specialized Silane Valve Manifold Box (VMB). Engineered specifically for the distribution of hazardous specialty gases, this new system provides a dual guarantee of safety and precision for mission-critical processes in the semiconductor, photovoltaic, and optoelectronics industries.

Silane (SiH₄) is a cornerstone of modern electronics manufacturing but presents extreme risks due to its pyrophoric and explosive nature. WOFLY’s new VMB series addresses these challenges through a combination of structural innovation and intelligent safety controls.

Advanced Distribution & Independent Control

The WOFLY VMB is designed to split a single upstream gas source into multiple independent distribution branches, supplying gas to several process tools simultaneously. Each branch features independent shut-off valves and pressure monitoring units, allowing for isolated maintenance and troubleshooting without interrupting the operation of other production lines.

Core Safety Features & Technical Excellence

1. Inert Purge & Displacement System

Equipped with built-in high-purity Nitrogen (PN2) purge and vacuum lines. This ensures thorough removal of residual silane before maintenance or equipment changes, strictly following safety standards to prevent spontaneous combustion upon air contact.

2. Real-time Monitoring & Interlock Alarms

Integrated high-precision pressure sensors and gauges provide millisecond-level response. The system is linked to pneumatic emergency shut-off valves and facility control centers, triggering immediate isolation if pressure anomalies or leaks are detected.

3. Negative Pressure Enclosure

The fully enclosed 316L stainless steel cabinet maintains a stable negative pressure. Any trace leaks are confined and safely extracted through a centralized exhaust system to an abatement unit, eliminating risks to the workshop environment.

4. Electronic Grade Purity

All wetted components are made of SS316L EP (Electropolished) grade stainless steel. Utilizing automatic orbital welding, the system ensures a clean, particle-free environment with a helium leak rate of ≤ 1×10⁻⁹ atm·cc/s, preserving the integrity of high-purity gas.

Wide-ranging Industry Applications

The versatility and robust design of the WOFLY Silane VMB make it the standard configuration for:

- Semiconductor Wafer Fab: Essential for thin-film deposition processes such as PECVD, LPCVD, and ALD.

- Photovoltaic Cell Production: Widely used in high-efficiency cell lines like TOPCon and HJT for silicon-based film deposition.

- Advanced Display Manufacturing: Supporting TFT-LCD, AMOLED, and Mini/Micro LED production.

- Research & Labs: Providing small-scale, precise distribution for material R&D and process verification.

"Safety and purity are non-negotiable in specialty gas handling," said the Technical Director at WOFLY. "Our new Silane VMB isn't just a distribution box; it's a comprehensive safety shield that allows our clients to scale their production with absolute confidence."
