[Special Stock] J.O. Begins Development of CNT Membrane for EUV Pellicle

Global carbon nanotube (CNT) leader J-O is showing strong performance. The news that it is actively advancing the development of next-generation extreme ultraviolet (EUV) pellicle CNT membrane technology to drive innovation in the semiconductor industry appears to be influencing its stock price.

As of 1:36 PM on the 7th, J-O is trading at 19,450 KRW, up 9.15% from the previous trading day.

On the 4th, J-O completed an agreement as a detailed lead institution for the project "Development of Carbon Nanotube Membrane Manufacturing Technology for EUV Pellicles," overseen by the Nano Convergence Industry Research Association. In addition to J-O, pellicle specialist company FST, as well as Hanyang University, POSTECH, and Inha University, are participating to collaborate on the development and commercialization of next-generation EUV pellicles using CNT membranes.

Through this business agreement, J-O plans to develop CNTs for semiconductor EUV pellicles by 2027 and carry out industry-academia collaborative research projects. The research tasks include securing detailed technologies for ▲ next-generation pellicle materials ▲ CNT membrane processes via dry processing ▲ and CNT membrane flare analysis and evaluation.

Pellicles serve to protect photomasks, which are plates that engrave circuits in the EUV process, from contaminants. The EUV process exposes wafers through light transmission, and during this process, pellicles minimize mask damage caused by particles (contaminants) that occur when light hits the wafer, thereby improving product yield. Pellicles are core components of the EUV process and are considered high value-added products, with prices ranging from several tens of millions of KRW to nearly 100 million KRW per unit.

J-O is a company with world-class CNT development technology, having developed CNTs for 20 years. Through the semiconductor EUV pellicle research project, it plans to expand its business scope from CNT conductive materials for secondary batteries to semiconductors. J-O is expected to further solidify its position in the market as a next-generation semiconductor innovative materials company.
