Restore water and air to their natural state

Production processes require water. They also can pollute the atmosphere. We need to work on two fronts: one, saving water, and two, developing technologies to reduce air and water pollutants.

We are reducing the amount of new water withdrawal by maximizing the reuse of water in production processes. Due to the expansion of semiconductor lines, the daily water withdrawal requirement at semiconductor business sites will more than double between 2022 and 2030. However, we have decided to keep the level from 2021 by increasing the reuse of water.

Starting in 2040, we will apply innovative technologies that treat air and water pollutants from semiconductor manufacturing process to a natural state to minimize the impact on the environment.

Reducing the use of
hazardous substances
for the health of our
customers and
employees

We strive to minimize any potential adverse effects on the health of our
customers, employees, or to the environment that may arise from
products containing hazardous substances or chemicals used at our
manufacturing sites. We have established and stringently manage
internal regulations that incorporate global environmental standards
such as the EU Directive on the RoHS (Restriction of Hazardous
Substances) and EU REACH (Registration, Evaluation, Authorisation and
Restriction of Chemicals). We will continue to monitor and
systematically respond to new regulatory standards, such as authorized
uses of PFAS (Per- and Polyfluoroalkyl Substances).
