HBM capacity constraints may limit AI chip supply and affect consumer DRAM prices
Problem
Recently, Samsung plans to more than double the output of HBM4 and HBM4E, yet comments highlight multiple bottlenecks in HBM production—complex manufacturing steps, sanctions on EUV equipment, and China's nascent domestic capacity still yielding low volumes. These constraints could limit AI chip supply and further depress consumer DRAM prices.
Pain points
- HBM production constraints limit AI chip capacity
- Consumer DRAM prices may further decline
- End users may not be able to purchase HBM products
Questions to verify
- Will end users actually be able to purchase HBM products?
- Is the current HBM capacity sufficient for AI accelerator demand?
- Are there alternative memory technologies that could alleviate the HBM bottleneck?

On a related note, I was reading yesterday that apparently the real bottleneck for Chinese production of AI accelerators is HBM production, not processors or ASML equipment... The problem is that HBM manufacture requires many steps (die thinning, via drilling, plating, alignment) where the equipment used by everyone else (Samsung, SK Hynix, Micron) is also blocked by sanctions, so the Chinese are having to develop all of this themselves too, which they have, but yields are currently low...
fact
Samsung is expected to more than double output of its HBM4 and HBM4E DRAM next year.
