Signs Samsung to build substrates, bolsters spend with other players

Nvidia has decided that its future prospects rest on an improved silicon substrate and packing supply chain, so has dipped into its giant pile of cash to ensure it can get the parts it needs by ensuring its suppliers have the resources needed to play their small part in keeping the flow of GPUs and AI processors strong.

It’s not unusual for manufacturers to invest in their suppliers, because it helps to create certainty and spread financial risk. For those deals to be announced at a major tech company’s conference – as Nvidia did at its Berlin GTC gabfest – is somewhat novel, suggesting the company feels the need to show investors it is working to ensure it can meet demand for its products, and that demand will persist for years.

Several of Nvidia’s announcements pertained to silicon substrates, aka wafers. Whatever you call them, they’re blank, round, silicon slabs onto which chipmakers etch circuits. They’re made by companies that sell to foundries like TSMC and Intel, which then turn them into chips of various flavours.

At GTC Berlin, Nvidia CEO Jensen Huang observed that demand for AI hardware is vast, but that “Capacity is the constraint.”

Specifically, capacity for activities like building…
