Samsung diverges from TSMC on FOPLP: retains 415×510mm panel size, targets 2028 mass production

Samsung's divergence from TSMC on FOPLP signals a strategic push toward self-reliance in advanced packaging. By maintaining the 415×510mm panel size, Samsung prioritizes controlled scaling over rapid expansion, contrasting with TSMC's aggressive rollout. This move will influence upstream suppliers, especially in EUV equipment and high-end substrates, reshaping production strategies. From a geopolitical standpoint, the decision reduces exposure to supply chain disruptions, particularly amid U.S.-China tech decoupling. Competitors like TSMC and UMC may accelerate their own FOPLP timelines to maintain edge. Over the next 12–24 months, packaging innovations will increasingly drive performance gains in AI and HPC chips, positioning packaging as a pivotal value driver in the semiconductor ecosystem.
