Glass substrates
+4.66%유리기판
Glass substrates are thin glass panels used as the base layer for advanced semiconductor packaging, where they are being explored as a replacement for organic materials to support larger, denser chip assemblies. Korean investors group related companies under this theme because the category spans glass material makers, equipment suppliers, and chip packaging players that could be involved in its development and commercialization. The theme is closely watched as a possible next step in high-performance computing and AI chip architecture, though its timeline and market size remain uncertain.
