Lee stated that hybrid bonding technology is not yet ready for HBM4E, a more advanced version of the memory technology. Instead, SK hynix is focusing on extending its MR-MUF (Multi-Relay Multi-Functional) technology through N, a move that aims to overcome the physical limitations of HBM5.
To address the 775-micron ceiling, SK hynix is exploring new ways to integrate its MR-MUF technology. By leveraging this technology, the company hopes to create more efficient and compact memory modules. Lee emphasized that hybrid bonding is a complex process that requires significant advancements in materials science and manufacturing techniques.
