Managing and Cutting Down on Chemicals

Various chemical substances are used in the process of manufacturing semiconductors and storage products.
In the Group, efforts are naturally made to limit the use of harmful chemical substances as much as possible and to find alternative harmless chemical substances, and consumption of chemical substances is reduced (optimization of consumption) by improving productivity through improving the manufacturing process and yield. We are also working to minimize the impact on the global environment of chemical substances by reusing and recycling them after use and detoxifying by way of exhaust gas treatment and wastewater treatment.
As seen above, by working to reduce and improve both the use (input) and emission/disposal (output) of chemical substances, we are promoting the reduction of environmental risks in our business activities, as well as contributing to the protection of the global environment by taking the ecosystem into consideration.
