Analyst Ming‑Chi Kuo said TSMC’s next‑generation advanced packaging CoPoS is
expected to reach mass production in H2 2028. His research finds glass
substrates will not replace ABF film: chip interconnects will be implemented by
chip‑side routing layers (RDL), glass vias/copper structures within glass
substrates, and ABF build‑up, so glass and ABF will coexist rather than
substitute for one another.
