S&S Tech was established in 2001 to be the first company to develop and produce blank masks, a key raw material in the semiconductor and display manufacturing process.

As the importance of blank masks has become more prominent due to the trend toward miniaturization and advancement of semiconductor and display processes, our company has focused on developing high value-added products through bold R&D investments, patent applications, and registrations, and is now a leading producer of world-class blank masks. It has established itself as a company. As the difficulty of microprocessing increases, we are also investing to become a leader in technological competition, and are also preparing to expand into EUV (extreme ultraviolet exposure process) products, which are the core of this.
