In the field of semiconductor manufacturing, where precision is pursued, even the smallest deviation in any process can affect chip yield and performance. Solenoid valves, as the invisible core of process fluid and gas control, support critical operations throughout the entire process, from the precise delivery of process gases and reliable distribution of chemical liquids to the stable maintenance of vacuum environments—they act like the neural switches of semiconductor production lines, ensuring every step of the process operates within controllable parameters.

 

As semiconductor processes advance to sub-10 nanometer and even more advanced nodes, the industry has imposed higher requirements on solenoid valve performance: faster response speed, more precise control accuracy, stronger media compatibility, stricter cleanliness standards, and ultra-long service life to withstand long-term high-frequency operation. After all, in chip manufacturing, even the tiniest particle shedding or fluid leakage can lead to the scrapping of an entire batch of wafers, making the reliability and cleanliness of solenoid valves core considerations.

 

 

As a world-leading manufacturer of high-quality valves and control devices, Bray International has developed a field-proven high-purity valve solution for the demanding scenarios of semiconductor fabs, focusing on three core principles—cleanliness, reliability, and adaptation to advanced processes—to safeguard critical stages of semiconductor manufacturing.

 

 

1. Reverse Osmosis Systems: The First Line of Defense in High-Purity Water Preparation  

Semiconductor fabs consume millions of gallons of water daily, covering everything from wafer cleaning to facility utilities, and the preparation of high-purity water is the foundation of all processes. Reverse osmosis, as the core process for high-purity water preparation, first pretreats raw water to remove solid impurities, then uses reverse osmosis membranes to remove organic compounds, with the resulting high-purity water stored and distributed throughout the fab. Bray's valve solutions are compatible with the entire reverse osmosis system, ensuring stable operation of raw water pretreatment and reverse osmosis processes; they also support wastewater recycling—purifying wastewater through reverse osmosis technology before discharge or reuse, helping fabs optimize water resource management.

 

 

2. Ultrapure Water (UPW) Preparation and Polishing: Cleanliness Assurance for Advanced Processes  

Ultrapure water (UPW) is one of the most demanding media in semiconductor manufacturing, requiring absolute cleanliness in every step from wafer cleaning and wet etching to chemical mechanical planarization (CMP). Bray's PFA-lined valves are specifically designed for corrosive and ultra-pure applications, supporting bidirectional shutoff and adapting to all scenarios of UPW polishing, storage, and distribution. They ensure no impurities are introduced during UPW transmission, perfectly meeting the zero contamination requirements of sub-10 nanometer chip manufacturing.

 

 

3. Water Recovery and Wastewater Treatment: Closed-Loop Support for Green Manufacturing  

Semiconductor manufacturing generates large volumes of wastewater. Effectively treating and recycling wastewater is not only key to cost control but also an inevitable trend in green manufacturing. Bray's butterfly valve solutions are designed for wastewater isolation, treatment, and reuse scenarios, with field-proven reliability in handling the entire process of wastewater recovery, treatment, and discharge. They help fabs achieve closed-loop water resource utilization and reduce environmental impact.

 

 

From high-purity water preparation to wastewater recovery, Bray's high-purity valve solutions span the core water process stages of semiconductor manufacturing. With their clean and reliable characteristics, they provide solid support for stable production and yield improvement in semiconductor fabs. In today's era of advancing semiconductor processes, solenoid valves and valves are no longer just control tools but enablers of advanced processes—and Bray's solutions, with their application-specific design and field-verified reliability, have become the preferred partner for semiconductor fabs tackling advanced process challenges.  

 

 

In the semiconductor manufacturing field, where success or failure is determined by millimeters, choosing the right valve solution means ensuring chip yield and production stability. Bray's high-purity valves, with their in-depth understanding of semiconductor processes, are safeguarding advanced chip manufacturing.
