Samsung Reportedly Targets 2 Nm Base Die for HBM4E

Posted on
Samsung is reportedly preparing a 2 nm logic base die for HBM4E, extending its process lead as HBM stacks move toward more active base die functions.

Quick Report

A new industry report says Samsung is preparing to apply its 2 nm node to HBM4E base die production, following its recent commercial HBM4 shipment and ongoing redesign work around HBM4E power delivery. This matters because the base die is no longer only a passive layer in advanced stacks and now contributes more directly to control and compute-adjacent functions.

If the plan holds, Samsung could extend process leadership versus competing HBM supply paths, with potential benefits in thermals, efficiency, and area use for next wave AI accelerators. The move also aligns with foundry utilization strategy, where internal base die demand can support broader 2 nm ramp objectives through upcoming fab capacity expansion.
