Why Onto Innovation (ONTO) Is Gaining From Advanced Node and Packaging Demand

Onto Innovation Inc. (NYSE:ONTO) is one of the best semiconductor equipment stocks to buy.

Onto Innovation Inc. (NYSE:ONTO) gave investors a fresh semiconductor-equipment angle on May 5, when it reported record quarterly revenue of $291.9 million for the first quarter of 2026, up 9.5% from $266.6 million in the prior-year period and nearly 10% higher sequentially. The company’s results were helped by demand across process-control markets tied to advanced nodes, advanced packaging, and memory, the exact parts of the chip supply chain where complexity tends to make inspection and metrology more important. Tiny defects, giant financial consequences. Semiconductor physics is not a forgiving landlord.

The company also said its Dragonfly G5 system was qualified at a leading 2.5D logic customer and a high-bandwidth memory customer, while its Atlas G6 system was selected by a second logic customer for gate-all-around metrology. Onto said advanced nodes grew 13% in the quarter and are positioned for about 25% growth for the full year. For the second quarter of 2026, the company guided revenue to $320 million to $330 million, and non-GAAP diluted EPS to $1.65 to $1.73.

Onto’s April 20 partnership with Rigaku adds another layer to the story. The company agreed to buy a 27% stake in Rigaku for about $710 million, while the two companies work on X-ray process-control solutions for increasingly complex logic, memory, and advanced packaging structures.

Onto Innovation Inc. (NYSE:ONTO) provides process-control equipment, inspection systems, metrology tools, lithography systems, software, and related solutions used across the semiconductor manufacturing value chain.
