NVIDIA announced plans to greatly increase substrate capacity by 2.5 times, expand optical engine manufacturing by 15 times, and fund semiconductor testing expansion in the US, signalling a shift from just improving GPU performance to scaling the entire AI chip production ecosystem.

This Wire brief sits within Fusion42's coverage of Semiconductors, and 1 source has reported it.

◆ ◆ The Wire takeaway

The race to mass-produce AI chips is shifting focus from chip design to industrial scale manufacturing and testing. If you supply packaging, testing, or optical components for AI chips, your market is about to multiply rapidly.
