How has ultrapure water (UPW) treatment changed in the microelectronics industry the last 20 years?

In answering that question, Brad Herbert, a principal engineer—facilities with ON Semiconductor in Gresham, OR, offers this observation: “In our business, the emphasis has shifted more toward water conservation and cost savings.” He further observes that tightening wastewater regulations around the world are driving new treatment and management strategies involving water use at microelectronics facilities. Mr. Herbert made these comments as part of an interview with GWI | Ultrapure.

In His Words

GWI | Ultrapure: In your work, how do you get involved with water treatment? Do you work at a single facility, or do you provide services to several ON Semiconductor fabs? Also, do you get involved in making buying decisions?

Mr. Herbert: “In my current position, I am responsible for engineering and operations support for all ultrapure water and wastewater treatment on the Gresham, OR, site. This includes strategic planning, capital expansions, project management, day-to-day operations support, troubleshooting, and coordination with factory operations. I also provide engineering support as needed for all of the ON Semiconductor sites, including the United States, Asia, and Europe. I am involved in all buying decisions at the Gresham site, including capital equipment purchases, consumables, and operations support contracts. I also support equipment and service purchases at other sites as needed.”
