Samsung Plans to Use Glass Substrates in Chips Starting from 2028

Samsung aims to adopt glass substrates in its chips by 2028, targeting the growing demand for advanced AI chips. The company is reportedly negotiating with suppliers about the dimensions of the glass plates, preferring a size of 100x100mm over the industry standard of 510x515mm to accelerate implementation.

Currently, Samsung uses silicon substrates in its semiconductors. Glass substrates offer advantages such as enabling larger, more complex, and energy-efficient chips, better mechanical stability, and reduced energy and signal loss, allowing higher communication speeds.

Intel also announced in 2023 that it is working on glass alternatives for silicon interposers.
