Clean Surface Technology Co. was established on April, 1977 as the first mask blanks maker in Japan and was able to reach its 37th anniversary in this April.
We deeply appreciated your support, guidance and encouragement.
The company has expanded the business scope from small size mask blanks for semiconductors to large size mask blanks for FPD, and the Half-Tone film, ahead of its time.
In addition, in response to demand from our customers for quality improvement, we developed new mask blanks corresponding to the high definition mask.
We will make every possible effort to develop higher quality products in response to the needs of our customers.
And as a good corporate citizen, we will strive to achieve social responsibility as a member of the local and the global community for the creation of a sustainable society.
We would like to ask your continued support in the years to come.
Clean Surface Technology Co.
President & CEO Hiromi Hidaka
