The employees, rather than the chairman, president or executives, are the main manufacturers and sellers of our silicon wafers. All employees of the SUMCO Group share the SUMCO Vision, maintain an awareness of profit and cost, and work to identify and solve issues. To cultivate this awareness among employees, CEO & Chairman of the Board regularly holds management briefings to all employees in order to share the management issues facing the Group in the current business environment change.

We also recognize that without high levels of employee motivation, we will be unable to realize the SUMCO Vision of becoming "World's Best in Technology" and "Stable Profitability Even during Economic Downturns." The SUMCO Group works to boost employee motivation by establishing a variety of award systems to appropriately recognize and reward employees' efforts and achievements.
Moreover, SUMCO actively promotes the creation of a comfortable working environment for our employees by offering a diverse range of work options and working support measures that can be tailored to the stage of each individual's life. In addition, we are advancing initiatives to support the balance between work and childcare, such as establishing an on-site nursery school at our largest facility, the Kyushu Factory (Imari), and providing a childcare support allowance as a subsidy for childcare expenses.
