Artificial intelligence grabs the headlines, but the quieter story sits in the factories racing to build the advanced packaging gear that makes those AI chips usable. With capital spending on these tools projected near $28b and customers hunting for scarce capacity, investors face a rare moment where plumbing becomes the prize. This article walks through three stocks exposed to that news, and why their positioning could matter for your portfolio decisions.
The three stocks below are only a first pass, and the full screen pulled out another 16 advanced packaging players with equally interesting stories that are not covered here.
If you want to identify patterns across that wider group and analyze which setups fit your risk appetite, head straight to the Advanced Semiconductor Manufacturing Equipment for AI Packaging screener .
Aehr Test Systems (AEHR)
Aehr Test Systems sits right on the fault line between AI chip packaging and reliability, supplying wafer and package burn in tools that customers need before those processors ever reach a server rack.
Aehr Test Systems designs and sells advanced test and burn in equipment, generating about US$50 million from this product line and carrying a roughly US$2 billion market cap.
"Rising AI processor and data center demand is feeding into Aehr Test Systems' FOX wafer-level and Sonoma package-level platforms, tied to large purchase orders, a record backlog of about US$100.6 million, and a fiscal 2027 revenue outlook of US$130 million to US$150 million that directly targets higher revenue and operating income."
What happens to those ambitions if a single assumption about future AI burn in intensity shifts even slightly?
If that question is on your mind, read the full narrative for Aehr Test Systems to see how Aehr Test Systems' test demand, capacity plans and AI exposure could be decoupling from the herd.
Cohu (COHU)
Cohu plugs directly into the advanced packaging story through test and inspection gear that checks complex chips and power devices before they leave the factory, which makes its positioning in AI infrastructure and high-performance computing particularly relevant for this screener.
Cohu generates about US$569 million from semiconductor test and inspection equipment and related services, and carries a roughly US$1.7b market cap.
"Cohu is capitalizing on the surge in high-performance computing and the complexity of modern semiconductors (AI infrastructure, GPUs, HBM, and display drivers) by rolling out advanced, configurable handler platforms and test solutions. This is positioning the company for potential market share gains and higher equipment sales, directly affecting top-line revenue."
What matters next is how any pressure on future test intensity and mix plays out in practice for Cohu's margins and cash generation.
Those shifting test economics are exactly why reading the full narrative for Cohu can help you see how Cohu's AI exposure, cash generation, and risk profile really align.
Camtek (CAMT)
Camtek plugs directly into the advanced semiconductor manufacturing equipment for AI packaging theme, because its inspection and metrology tools sit on the same wafer and panel lines that handle chiplets, HBM and other AI data center builds. The business is valued at about US$4.3b.
Camtek develops inspection and metrology systems for advanced semiconductor packaging and 3D structures, supplying foundries, OSATs and chip manufacturers with platforms such as Hawk, Eagle G5 and MicroProf tools used on AI focused packaging lines. Its market cap is about US$4.3b.
Camtek's real leverage to the AI packaging story lies in how many inspection steps its tools win on each wafer and panel over the next few years.
"Accelerating AI and high performance computing demand is feeding through to advanced packaging and HBM orders for Camtek, with roughly 80% of more than US$600 million of 2026 year to date orders tied to these applications and scheduled for delivery through 2026 and into 2027, which can support multi year revenue growth."
What happens to Camtek's earnings power if a single assumption about that AI packaging order mix or pricing pressure shifts even slightly?
If that risk keeps nagging at you, the full narrative for Camtek explains how Camtek's AI packaging exposure, order quality and execution could be reshaping its long term potential.
