Samsung is pushing to complete development of its 3D Cube-H packaging technology by early 2027, ZDNet Korea reported.
Samsung uses hybrid bonding to stack logic and HBM
This is Samsung’s answer to TSMC’s CoWoS and Intel’s Foveros. The platform uses hybrid bonding to stack logic and HBM together.
Waiting on customer evaluations
While this schedule positions Samsung to compete for future AI accelerators, the early 2027 date marks the point when the design kit will be finished and client assessments will commence. That is not the same as shipping at scale. Samsung expects large-scale hybrid bonding production around 2030, per earlier TrendForce reporting.
Playing catch-up in silicon
TSMC has been shipping CoWoS in volume since 2012. Intel has been working Foveros since 2019. By moving into this space, Samsung is attempting to bridge the gap on a technology that hyperscalers currently rely on for their existing designs.
Ramping up for 2030 production
The question is not whether the technology works in the lab. The main challenge is if Samsung can accelerate its output sufficiently to vie for 2028-2029 silicon orders that have likely been secured by other providers.
Advanced packaging constraints
Advanced packaging capacity is the constraint right now. Every fab that can deliver hybrid bonding at reasonable yields has a line out the door. Samsung adding another option helps, but only if they can ship at scale when customers need it.
The generation after next
A 2027 design kit with 2030 production means the real competition is for the generation after next. That is fine if the goal is to establish a position in a growing market. It is harder if the goal is to catch TSMC.
