AI chips get the headlines, but the quieter story sits in who can actually assemble, package and test them as Nvidia locks in multi-year deals and billions of dollars of future supply. That shift pulls more attention toward the supply chain behind the hype. If you care about where capital is flowing next rather than last quarter’s winners, this article walks through three stocks exposed to that Nvidia news and explains why their role in AI infrastructure matters.
The stocks highlighted below are just a starting sample, and the full screen surfaced 30 more companies with equally compelling AI assembly and testing narratives that are not covered here.
To identify, analyze, and act on the highest conviction AI packaging and test plays in one place, head straight into the AI Semiconductor Assembly & Testing Supply Chain screener.
Onto Innovation (ONTO)
Onto Innovation sits where AI chips leave the fab and head into complex packaging, supplying the inspection and metrology gear that keeps advanced AI substrates and OSAT lines running. Its entire US$1.1b in revenue is tied to semiconductor equipment and services, and it has a roughly US$10b market value.
For investors tracking Nvidia driven capacity plans, Onto Innovation is one of the clearest pure plays on the AI packaging bottleneck, so it is worth hearing how management frames the next leg of demand in its own words.
"TSMC Production RampVolume shipments for Dragonfly G5 systems are expected to begin during mid-2026, with revenue contributions potentially accelerating during the second half of the year."
What happens to Onto Innovation’s earnings power if a single assumption about how quickly AI packaging customers absorb that extra tool capacity breaks?
If that question is on your mind, read the full narrative for Onto Innovation to see how different AI packaging demand paths could reshape Onto Innovation’s risk reward profile.
Kulicke and Soffa Industries (KLIC)
Kulicke and Soffa Industries sells the assembly tools and consumables that turn finished wafers into packaged chips, making it a direct way to follow AI related OSAT and packaging capacity builds. The business generated about US$588 million from Ball Bonding Equipment, US$171 million from Aftermarket Products & Services, US$87 million from Advanced Solutions, US$80 million from Wedge Bonding, and US$24 million from other lines, and the stock carries a market value of roughly US$4.0b.
Kulicke and Soffa Industries links cleanly into the AI Semiconductor Assembly & Testing Supply Chain theme because its bonding and thermocompression systems are the kind of gear OSATs rely on when Nvidia’s partners invest in new advanced packaging lines.
"Heavy emphasis on advanced packaging tools for chiplet architectures and heterogeneous integration concentrates exposure in areas where customer qualification cycles can be long and order timing uneven."
For anyone watching Kulicke and Soffa, what happens if a single assumption about how smoothly those high value tools ramp into volume production breaks?
If that smooth ramp is the hinge, read the full narrative for Kulicke and Soffa Industries to see how AI demand, tooling cycles and consumables could be quietly accelerating Kulicke and Soffa’s story.
Kinsus Interconnect Technology (TWSE:3189)
Kinsus Interconnect Technology builds advanced IC substrates and packaging platforms that sit directly in the AI semiconductor assembly chain, supplying carriers for processors, chipsets and RF modules. The IC Substrate unit produced about NT$36.9b of revenue, while Optics added roughly NT$7.8b. The stock carries a market value of around NT$545.4b.
Kinsus Interconnect Technology gives you exposure to AI oriented substrates and interconnects, with Nvidia linked capacity expansions indicating potential demand for the kind of high density packages it sells. Earnings, margins and index inclusion already show how tightly performance now ties back to one unresolved pressure on that substrate cycle.
That unresolved pressure is exactly why it helps to read the 3 key rewards and 2 important warning signs (1 is major!) before substrate sentiment and AI hype fully converge.
