Overview
Kurita Water Industries is headquartered in Tokyo. Its semiconductor business centres on systems that produce ultrapure water, which is used to rinse wafers between process steps.
It also designs wastewater treatment systems, so it can handle a fab's water treatment as a whole.
Business: Ultrapure water systems and wastewater treatment
Why it matters
- A fab uses large volumes of ultrapure water, and its purity requirements tighten with each process node.
- Water supply and recycling are often a deciding factor when a site is chosen for a new fab.
