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 intake by increasing the reuse rate of water used in production processes. Due to the expansion of semiconductor lines, the daily water intake 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 rate of water.

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

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

We are reducing the use of harmful substances at production sites that could negatively impact the environment and/or human health. We have established and strictly follow in-house rules that reflect global environmental standards, such as RoHS (Guidelines for Restricting the Use of Hazardous Substances in Electrical and Electronic Products) and REACH (EU Chemicals Registration, Evaluation, Permission, Restriction System).
