Ultrapure water for semiconductor and microelectronics manufacturing
We are specialists in the design, build, installation and maintenance of semiconductor-grade water treatment systems for the highly precise needs of the industry.
We create cost effective, customised solutions to ensure the highest level of water purity required at every stage of semiconductor production from the initial cleaning of wafers to the final fabrication of semiconductor and microelectronics components.
From consultation to commissioning: water management for the semiconductor industry
We are experts in water chemistry and process engineering and understand the unique demands and specifications of the semiconductor and microelectronics industry.
With over 40 years behind us, we have the knowledge and skills to tailor water systems to meet the stringent parameters of ultrapure water required in controlling contamination, facilitating chemical processes and preparing surfaces in semiconductor fabrication.
We have established ourselves as a turnkey partner in the sector, providing consultation, plant and distribution loop design, UK manufacture, installation and commissioning services.
Our solutions are supported by a nationwide team of specialist service engineers dedicated to maintenance, ensuring the integrity and reliability of your pure water supply. We also offer comprehensive service contracts.
Ultrapure water treatment solutions for the semiconductor and microelectronics industry
Semiconductor manufacturing demands ultrapure water – water with a resistivity of 18.2 megaohm-cm at 25°C, free of contaminants and impurities.
We employ advanced technologies such as reverse osmosis (RO), deionisation (DI), ultraviolet sterilisation (UV) and ultrafiltration (UF) to remove ions, particles, TOCs, TDS, oxidants and bacteria to meet the industries ever increasing water standards to prevent the costly rejection of components and manufacturing issues.
Our solutions provide gradations of purity according to ASTM D5127 Standard Guide for Ultrapure Water Used in the Electronics and Semiconductor Industries:
Type | Use |
---|---|
Type E-1 | For use in the production of devices having line widths between 0.5 and 1.0 μm. |
Type E-1.1 | For use in the production of devices having line widths between 0.25 and 0.35 μm. |
Type E-1.2 | For use in the production of devices having line widths between 0.09 and 0.18 μm. |
Type E-1.3 | For use in the production of devices having line widths between 0.065 and 0.032 μm. |
Type E-2 | For use in the production of devices that have dimensions between 1 and 5 μm. |
Type E-3 | For use in the production of devices having dimensions larger than 5 μm. This grade may be used to produce larger components and some small components not affected by trace amounts of impurities. |
Type E-4 | For use in the preparation of plating solutions and for other applications where the water being used can be of lesser quality. |
