Advanced packaging, CoWoS, and HBM
Why the deliverable is a qualified system, not an isolated logic die.
The package is part of the product
Advanced packages connect logic, memory, substrates, power delivery, and thermal behavior. A leading-edge die cannot become a deployable accelerator unless the rest of the qualified stack is available.
Outlooks are dated
Supplier forecasts and executive shortage statements can be valuable, but they are not permanent facts. Treat their dates, sources, and caveats as essential context.
Policy follows the bottleneck
Public support for advanced packaging is tracked separately from private expansion plans and from customer demand.
Use the system view
When evaluating a new accelerator, ask which logic die, memory stack, substrate, package, test flow, and cooling approach are qualified together. The bottleneck may be a narrow step in that combined system rather than the most visible chip.
