Glass substrates allow for tighter wiring and maintain a flatter profile than plastic plates, which are currently hitting physical limits in advanced packaging. A 2 year timeline is typically insufficient to produce a fully qualified part, creating a competitive race between the established organic board stack in Taiwan and emerging glass production lines in Japan and South Korea.
