### The Client

In 2005, STMicroelectronics Pte Ltd awarded Veolia Water Solutions & Technologies (Veolia) the project to build the ultra-pure water (UPW) purification treatment plant - AMK6E (loop 5) in Singapore with a production capacity of 160m³/hr. STMicroelectronics is a global leader in developing and delivering System-on-Chip (SoC) and semiconductor solutions across the spectrum of microelectronics.

As one of the world’s top ten semiconductor suppliers since 1999, STMicroelectronics has leading-edge manufacturing facilities on four continents, including a 200mm wafer fab in Singapore, where proper microelectronics water treatment is essential to maintain production quality.



 

 

 



### The Client’s Needs

To meet the growing demand of the semiconductor industry, STMicroelectronics Pte Ltd was seeking a reliable Ultra Pure Water (UPW) partner capable of delivering purified water treatment projects on a very fast track (4 months from award to water certification).

The company required a system that could consistently provide high-quality water purification while meeting the strict technical specifications necessary for a 200mm wafer fab. The solution had to ensure long-term reliability and compliance with industry standards for microelectronics water treatment.

### Veolia's Solution - Microelectronic Water Purification

To reach the TOC and Resistivity criteria, the raw water is treated in the Primary Make-Up system using advanced water-purification technologies such as UV, Membrane Degasifier, and Continuous De-ionization (CEDI) – tailored for [semiconductor water treatments](https://www.asia.veoliawatertechnologies.com/en/core-markets/electronics-and-photovoltaics).

The Continuous De-ionization (CEDI) process ensures consistent purified water treatment with a high percentage of feed water ion removal. CEDI systems operate without chemicals, 24 hours a day, 7 days a week, eliminating regeneration downtime.

Ultrafiltration membranes are used in the polishing loop to guarantee continuous high-quality water at the point of use.

Thanks to intelligent engineering design, Veolia successfully incorporated these new water purification systems into the existing plant without requiring shutdown.
