JNTC completed its domestic production line in June and expects to begin full-scale manufacturing in August, following test runs in July. Unlike competitors, JNTC built and engineered most of its core production equipment in-house, enabling cost efficiency and full process independence. This approach cut initial investment costs to about one-fifth of the industry average.
The newly unveiled substrates support various sizes and thicknesses and feature high-precision via holes (0% microcrack). JNTC also developed its own etching, metalizing (void free), and processing technologies, achieving yields above 90% with minimal defects. Additional packaging features such as alignment marks and cavities have undergone performance verification with global semiconductor leaders.
'TGV glass substrates are emerging as critical components in next-gen semiconductor packaging,' Cho said. 'We have secured a clear edge in quality and cost, and are currently working with 16 global partners across the semiconductor ecosystem. This launch signals our ambition to become a leading global player in precision glass materials.'
