In September 2023, Intel released a processor based on next-generation advanced packaging technology with a glass substrate. Intel stated that the glass substrate would lay the foundation for achieving an astonishing scale of one trillion transistors in a single package over the next decade. Recently, rumors have emerged that Intel plans to begin mass production of glass substrates as early as 2026. Intel has invested nearly a decade in glass substrate technology and currently has a complete glass research line in Arizona, USA.
Samsung‘s Initiative in Glass Substrate Development
Samsung has also formed an alliance comprising Samsung Electro-Mechanics, Samsung Electronics, and Samsung Display to jointly develop glass substrates. Their goal is to achieve large-scale mass production of the technology by 2026, ahead of Intel. It is reported that Samsung Electro-Mechanics plans to install all necessary equipment on its trial production line by September this year and begin operations in the fourth quarter.
SKC’s Investment in Glass Substrate Production
SKC’s U.S. subsidiary, Absolics, invested approximately 300 billion Korean won to establish the first glass substrate production facility in Covington, Georgia, U.S., in 2022. Recently, the company announced that the facility has been completed and has started mass production of prototype products. All these signs indicate that the trend of replacing traditional organic substrates with glass substrates is accelerating.
China’s Rapid Development in Glass Substrate Technology
Compared to foreign countries, China’s research and development in glass substrates is also advancing rapidly, especially in the application of glass substrates in Mini LED/Micro LED technology. Chinese companies, such as Ledman (300162.SZ) and WG Tech (603773.SH), have reached industry-leading levels in this field.
Among them, Ledman is one of the first companies in China to invest in the development of glass substrates and achieve results. After five years of R&D, the company released the world’s first PM-driven glass substrate Micro LED display screen in October 2023. According to Ledman, this 220-inch Ledman PM-driven glass substrate Micro LED display screen uses a glass substrate and Ledman’s proprietary new COB packaging patent technology, offering a cost-effective product that balances display performance with cost.
Furthermore, according to information from Ledman Interactive Easy, the company has already achieved small-scale trial production of PM-driven glass substrate Micro LED display panels and continues to explore and upgrade glass substrate technology by constructing a pilot production base.
Ledman also stated that it is committed to the PM + glass substrate + Micro LED technology route and aims to expand the use of glass substrates in Ledman’s smart conference interactive display systems, smart education interactive display systems, and ultra-high-definition home giant screens, along with a series of large-size Micro LED display products and solutions, to comprehensively meet the future demand for low-cost, low-energy consumption solutions in specialized, commercial, and home display applications.
