Company Overview

Onto Innovation Inc. is a semiconductor process control company that provides advanced metrology, inspection, and lithography solutions used in the manufacturing of semiconductors and advanced electronic devices. The company operates within the semiconductor equipment and advanced packaging industries, serving customers across logic, memory, foundry, and advanced packaging markets. Its core offerings support critical manufacturing steps that improve yield, performance, and reliability in semiconductor fabrication.

The company’s primary revenue drivers are process control tools used for inspection and metrology, as well as lithography systems supporting advanced packaging and specialty device manufacturing. Onto Innovation is positioned as a focused supplier addressing increasingly complex manufacturing challenges driven by heterogeneous integration, advanced packaging, and device scaling. The company was formed in 2019 through the merger of Nanometrics Incorporated and Rudolph Technologies, Inc., combining complementary technology portfolios and customer bases to create a more comprehensive process control platform.

Business Operations

Onto Innovation generates revenue through the sale of semiconductor manufacturing equipment, software, and related services. Its operations are organized around key process control capabilities that address optical and materials metrology, macro defect inspection, and lithography for advanced packaging applications. These solutions are used throughout wafer fabrication and back-end packaging workflows, supporting both high-volume manufacturing and specialty applications.

The company operates globally, with manufacturing, research and development, sales, and customer support functions spanning North America, Asia-Pacific, and Europe. Onto Innovation controls proprietary optical, materials characterization, and imaging technologies that are integrated into its product platforms. The company maintains long-term relationships with leading semiconductor manufacturers and outsourced semiconductor assembly and test providers, supported by localized service teams and applications engineers.

Strategic Position & Investments

Onto Innovation’s strategic direction emphasizes capitalizing on long-term semiconductor industry trends, particularly the growth of advanced packaging, heterogeneous integration, and increasing process complexity. The company continues to invest in research and development to enhance sensitivity, throughput, and data analytics across its inspection and metrology platforms, aligning its roadmap with customers’ next-generation device requirements.

Rather than pursuing frequent large-scale acquisitions, Onto Innovation has focused on organic innovation and selective technology investments to extend its product capabilities. The 2019 merger that created the company remains its most significant strategic transaction, providing scale and portfolio breadth. The company is also engaged in emerging areas such as panel-level packaging and advanced node process control, where adoption is still evolving and market penetration is expanding.
