[Edaily Reporter Lee Hye-ra] J&T Co. hit the daily price limit shortly after the market opened.
According to MP Doctor on the 19th, #JNT was trading at 21,000 won as of 9:02 a.m., up 29.95% from the previous trading day.
It appears that buying interest surged following news that the company had successfully developed the world’s first 2.0mmT TGV glass substrate.
The company explained that day that it now possesses a multi-product lineup with glass thicknesses ranging from a minimum of 0.3 mmT to a maximum of 2.0 mmT. The company stated that it has already received validation from some Taiwanese and South Korean substrate manufacturers, and that validation is currently underway with a Japanese manufacturer. It also reported that it has already begun developing a new product with a glass thickness of 3.0 mmT, skipping the intermediate stages.
Since entering the semiconductor glass substrate business in 2024, JNT has been participating in new projects for two of the world’s largest integrated semiconductor companies. Last year, the company completed vertical integration across all production processes by merging with its subsidiary “COMET,” which specializes in plating and etching processes. By incorporating these core technologies into equipment manufactured in-house by its affiliate, Jinwoo Engineering, JNT significantly strengthened its quality and cost competitiveness, establishing Korea’s first TGV mass production line in October of last year.
