AI Substrates Break 40x EUV Limits; Samsung and SK Hynix Thermal Tech Decides the Winner

Reports say AI substrate technology has broken the 40x EUV limit, making thermal management the key battleground between Samsung and SK Hynix in next-generation AI memory. If SK Hynix keeps its edge in thermal tech, its high-value HBM lineup becomes more competitive, supporting the stock over the medium term; near-term there is little hard earnings catalyst, so the impact is neutral.
