AI Interposers Grow Larger, Raising HBM4E Cooling Challenges: How Samsung, SK hynix Are Responding

TrendForce reported that as AI accelerator interposers grow larger, cooling and packaging for HBM4E become significantly harder, prompting Samsung and SK hynix to adjust designs and processes. The trend affects next-generation HBM yields and ramp timing; the short-term stock impact is neutral, while SK hynix could gain HBM share and pricing power in the long run if it solves the cooling bottleneck first.
