Semiconductors

Bray's Comprehensive line of valves, actuators and accessories are engineered, and field proven for demanding applications in semiconductor wafer fabs, where crevice free surface finishes up to 5 RA, guaranteed passivation of wetted surfaces, and reliability are mission-critical to the chip manufacturing process. Bray's specialized PFA Lined isolation and control valves are ideally suited for wet process fluid, and reduced particle shedding in manufacturing the next-generation of sub-10 nm microchips.

As lithography shrinks below 10nm the requirement for ultrapure water becomes extremely critical to the wafer fabrication process. Ultrapure water (UPW) is water that has been purified to extremely stringent specifications to establish specific composition and properties. Ultrapure water is generated by processing high purity water though a "polish system" using ultrahigh purity piping, also known as pvdf piping, to removing contaminants, minerals, microorganisms, and trace organic and nonorganic chemicals and output specification-grade water for use in the Wafer FAB. As defined by SEMI F63 for the UPW Grade used in Semiconductor manufacturing, the Bray product portfolio is designed to meet or exceed the most stringent industry requirements as required in SEMI F104 & SEMI F54. Bray Semiconductor valves are cleaned, bagged, and tagged in Bray's clean rooms, ensuring valves meet these stringent requirements.  Bray valves are found in UPW Polishing solutions, storage and distribution systems including wafer cleaning, rinsing, surface conditioning, wet etch, solvent process and Chemical Mechanical Planarization.

Deionization ("DI Water" or "Demineralization") simply means the removal of ions. Deionized water (DI water, DIW or de-ionized water), often synonymous with demineralized water / DM water, is water that has had almost all of its mineral ions removed, such as cations like sodium, calcium, iron, and copper, and anions such as chloride and sulfate. Deionized water is water that has had 99% of all of its mineral ions removed, resulting in a bacteria-free purified water. Deionized water is typically produced using an electrically charged ion exchange process such as an ion exchange resin tank also called a Mixed Deionize Tank or an Ion Exchange Resin tank system.  It takes more than 6000 gallons of deionized water (DI) to process a single 300mm wafer in a semiconductor manufacturing fab. It takes 4-6 gallons of raw city water to generate each gallon of Deionized water.

Water Management is essential to the Semiconductor Industry. In semiconductor manufacturing, facilities rely on Ultra-Pure Water (UPW) for wafer processing. After use, the UPW water is discharged from the system as effluent. Discharge effluent typically contains hazardous chemicals and metal ions such as cyanide, pyrazole, piranha acid, peroxymonosulfuric acid and other toxic compounds. Due to the toxicity of effluent water, it must be treated and reused or discharged from the wafer fab as pure clean water. Bray valves for water reclamation, effluent treatment, recycling, and discharge are field proven.
