What happened
Samsung Electronics is reportedly planning to allocate more than half of its 4nm process capacity to the production of HBM4 base dies, according to a person familiar with the matter.
The 4nm process is currently in full production, with HBM4 base dies accounting for 50% to 60% of total output. This high proportion is expected to be maintained through the second half of this year.
Why it matters
This strategic allocation indicates Samsung's focus on high-bandwidth memory for AI applications, potentially impacting its semiconductor business and competitive positioning in the memory market.
The sustained high ratio suggests strong demand for HBM4, which could influence supply dynamics and pricing in the advanced memory segment.
Key facts
Samsung plans to dedicate over half of its 4nm capacity to HBM4 base die production.
HBM4 base dies currently represent 50-60% of Samsung's 4nm output.
The high proportion is expected to continue through the second half of the year.
What to watch next
