So, if you're looking to understand the mechanics behind the chips powering tomorrow, let's break down the history, mission, and revenue engine of this essential US-based firm.

Onto Innovation Inc. (ONTO) History

Onto Innovation Inc. is a powerful force in semiconductor process control, but its origin story is not a typical startup tale; it's a strategic merger that combined two decades-old industry leaders to create a unified, global entity. The company you see today was engineered to integrate complementary technologies, specifically in metrology and inspection, to solve the most complex yield issues in advanced microelectronics manufacturing.

This consolidation brought together decades of intellectual property and a combined customer base, allowing the new company to immediately position itself as a top-tier semiconductor capital equipment supplier in the U.S..

Given Company's Founding Timeline

Year established

Onto Innovation Inc. was officially established on October 25, 2019, through a merger of equals between Rudolph Technologies, Inc. and Nanometrics Incorporated.

Original location

The merged entity established its headquarters in Wilmington, Massachusetts, the former headquarters of Rudolph Technologies.

Founding team members

As a merger of two publicly traded companies, the founding was led by the executive teams and Boards of both predecessors. The combined company's leadership was headed by Michael P. Plisinski as Chief Executive Officer.

Initial capital/funding

The newly formed company started with a strong financial footing, reporting a balance sheet with over $300 million in cash, cash equivalents, and marketable securities at the time of closing, and importantly, no debt.

Given Company's Evolution Milestones

Given Company's Transformative Moments

The single most transformative decision was the October 2019 merger of equals. This wasn't just a financial transaction; it was a strategic move to create a one-stop-shop for process control (the tools and software that monitor and improve manufacturing yield) across the entire semiconductor value chain.

Honestly, without that merger, neither company alone could have achieved the breadth of technology Onto Innovation now offers. The combined trailing twelve-month revenue as of late 2025 sits at approximately $1 billion, a scale that commands attention in the capital equipment market.

• Integration of Product Lines: The merger successfully combined Rudolph's strength in macro defect inspection and lithography with Nanometrics' expertise in optical metrology (measuring film thickness and critical dimensions), offering a complete solution from bare silicon wafers to final advanced packaging.
• The AI-Driven Product Pivot: The 2025 launch of the Atlas® G6 system, coupled with the expected near doubling of revenue in advanced nodes markets in 2025, shows a clear strategic shift toward supporting the explosive growth of Artificial Intelligence (AI) and advanced logic/memory devices.
• The Semilab Acquisition: The November 2025 acquisition of Semilab's materials analysis product lines for about $495 million was a defintely bold move. It immediately strengthened the company's position in high-growth segments like power semiconductors and AI-enabling advanced packaging.
