Aggregating materials: blank film products have passed mass production validation by domestic and foreign semiconductor customers such as SK Hynix, and have achieved mass production sales.

JUHO material announced on June 26th on the interactive platform that currently, the company's blank mask products have been mass-produced and verified by domestic and foreign semiconductor customers such as SK Hynix, TMC, Disco, and Zhongwei. The feedback from customers has been positive, and mass sales have been achieved. In terms of future market expansion and customer verification, the company adopts a strategy of "Korean products for initial verification, domestic production capacity for replacement". Currently, the company has completed technical exchanges with several domestic Fab factories and third-party mask factories. After the completion of the acquisition and integration, customers will prioritize the use of Korean-produced blank masks for at least six months of quality and consistency verification. Once verified, customers will quickly introduce them into domestic factories for localized production.
