JNTC has recorded an upper limit rise in stock prices following the announcement of its successful development of the world's first 2.0mm T TGV glass substrate.
According to the Korea Exchange, as of 12:52 PM on June 19, JNTC's shares were trading at 21,000 won, up 4,840 won (29.95%) from the previous trading day.
The company's announcement of its groundbreaking achievement in developing a high-difficulty 2.0mm T TGV glass substrate has improved investor sentiment.
With this development, JNTC has secured a multi-lineup of glass thicknesses ranging from a minimum of 0.3mm T to a maximum of 2.0mm T. The company has completed verification with some substrate manufacturers in Taiwan and South Korea, and is currently undergoing verification with a Japanese material manufacturer.
JNTC stated that its TGV glass substrate has passed reliability tests from substrate manufacturers, achieving crack-free verification in the challenging area of glass micro-cracks.
Since entering the semiconductor glass substrate business in 2024, JNTC has participated in new projects with two global comprehensive semiconductor companies.
Last year, the company merged its subsidiary COMET, which specializes in plating and etching processes, and established vertical integration across all production processes. In October of last year, it set up the first TGV mass production line in South Korea based on the facilities of its affiliate Jinwoo Engineering.
A company representative remarked, "By securing core technology for the 2.0mm T semiconductor TGV glass substrate, we have strengthened our leadership in the industry."
