The company used its Advanced MR-MUF packaging to achieve structural stability and a 17% heat resistance improvement. While mass production timing remains unconfirmed, the milestone reinforces SK Hynix's lead in the HBM market, where it is closely tied to Nvidia's AI accelerator supply chain. The announcement drove SK Hynix shares to near record highs. The broader context includes a memory market shift from glut to scarcity, with AI infrastructure demand pulling capacity toward HBM and causing conventional memory shortages affecting consumer devices. ## Full article daily.dev links to this article rather than hosting it.
