JNTC Succeeds in World’s First Development of High-Difficulty TGV Glass Substrate with 2.0mm Thickness

JNTC has entered the full-fledged stage of expanding the global supply chain for TGV glass substrates.

JNTC (Co-CEOs Namhyuk Cho and Yoonjung Jang), which is growing as a global advanced materials company, officially announced on June 19 that it has succeeded in the world’s first development of a high-difficulty TGV glass substrate with a thickness of 2.0mmT.

With this achievement, the company now possesses a multi-lineup of glass substrates ranging from a minimum thickness of 0.3mmT to a maximum of 2.0mmT. JNTC revealed that the product has already been validated by certain substrate manufacturers in Taiwan and Korea, and validation with a Japanese materials manufacturer is currently underway. Furthermore, the company has already started developing the next-generation product at 3.0mmT glass thickness without any intermediate steps.

In particular, for TGV glass substrates manufactured by JNTC, it is especially significant that the products have passed strict reliability tests by substrate manufacturers and have been certified as crack-free with regard to the industry’s most challenging issue: glass micro-cracks.

Since entering the semiconductor glass substrate business in 2024, JNTC is currently participating in new projects with two of the world’s largest comprehensive semiconductor companies. The company appears to have secured industry leadership by acquiring core technology elements for these highly advanced 2.0mmT semiconductor TGV glass substrates.

Last year, JNTC completed vertical integration of all production processes by merging its specialized subsidiary COMET, which focused on plating and etching processes. By internalizing key technologies into equipment independently developed by its affiliate Jinwoo Engineering, JNTC dramatically enhanced its quality and cost competitiveness, and in October last year, established Korea’s first TGV mass production line.

Additionally, a company representative stated, “We have become the first in the world to secure the core technology for the highly difficult 2.0mmT TGV substrate, successfully realizing customer-tailored products. We have also received proposals from some customers regarding the unit cell-cut processing stage, and have already secured processing technology for this as well.”

JNTC added, “Based on these technological capabilities, we have been carrying out various projects and evaluations with global top-tier semiconductor companies, as well as substrate manufacturers in Greater China, Japan, Europe, and Korea, in preparation for mass production in 2027. In late May, we entered the stage of materializing our business through an MOU with a major Korean conglomerate, and in July, we expect to sign an additional contract with a Japanese global substrate manufacturer. Future new contracts will be disclosed sequentially.”

JNTC CEO Namhyuk Cho commented, “The TGV glass substrate business is a major new long-term growth axis for JNTC, and with leading technology, excellent quality, and cost competitiveness, our company will secure a very important position as a global advanced materials leader in the semiconductor market focused on AI.”
