U.S. focuses on invigorating ‘chiplets’ to stay cutting-edge in tech

Some folks I work with are interested in chiplets for secure&#x2F;defense purposes. If you don&#x27;t trust the fab but you do trust the integrator, the fab can make multiple little modules with well-defined interfaces, and your integrator can instrument the interfaces more easily than an entire chip.

I am impressed by the fabrication technology for these heterogenous systems. It was already complex enough to fabricate a CPU, but chiplets require incredible precision for placing the die on the interposer wafer for soldering. And the coplanarity of the whole assembly is critical, else it will be impossible to effectively cool. It&#x27;s incredible that any of it works.

Why chiplets? Can anyone explain to me why I&#x27;d want chiplets as opposed to a processor embedded in a Field Programmable Gate Array? Seems like development would be infinitely cheaper and the possibilities far more dynamic? Chiplets seem slow and expensive to develop. Once built they&#x27;d be completely static and probably necessarily replaced by the subsequent version in 3-5 years.

Kinda ironic how the article is about chiplets, but all the factory photos are of an old school wire bonded PGA packaging line... But maybe that&#x27;s the point, you can&#x27;t find a chiplet factory within the borders of the USA to photograph for a story?

I&#x27;m not the OP, but I&#x27;d be curious for an informed HN reader&#x27;s take on this.

I am curious how Cerebras 850,000 core CPU fits in all this chip &#x2F; chiplets categories
