What it is
Through-silicon vias (TSVs) are vertical copper interconnects drilled through thinned DRAM dies that let 8-16 dies stack and communicate, and the associated stacking/bonding (MR-MUF at SK Hynix, TC-NCF at Samsung, and a move toward hybrid bonding for HBM4/HBM4E) is the yield-limiting art of HBM manufacture. As stacks grow taller and dies thinner, warpage, thermal dissipation, and bonding yield become the gating engineering problems. Hybrid bonding is expected to displace microbump stacking in future HBM generations.

Times are New York time. Free sources are pulled on the schedule shown by the pipeline runner (data/corpus/run_pipelines.py), which logs every run; paid sources run only with the owner's yes; filings and newsroom pages are re-read when a new document is filed.
Links come from the AI Systems Map ontology. Deals carry the filing's own wording and a quote, checked against the document; latest source 2026-10-26. Not investment advice.
