HBM beyond 16 layers brings memory makers\' hybrid bonding shift into view

As high-bandwidth memory stacks move beyond 16 layers, a shift in bonding technology is coming into view, with the three memory makers reviewing a phased introduction of hybrid bonding from HBM4 or later generations. The move reflects limits in conventional thermal compression bonding, though cost burdens are expected to keep MR-MUF processes in parallel for now. Equipment suppliers are adjusting as supply dynamics may change depending on future mass-production partner choices.
