Onto Innovation (ONTO)

Its tools are used in areas such as wafer fabrication, advanced packaging, compound semiconductors, power devices, image sensors, and other microelectronics applications. Onto’s portfolio combines hardware for measuring film thickness, dimensions, topography, and defects with analytics software that turns manufacturing data into actionable process insights. This positions the company within a critical part of the semiconductor supply chain, where tighter geometries, heterogeneous integration, and packaging innovation increase the need for precise control.

Onto serves customers across major electronics manufacturing regions, including the United States, Taiwan, South Korea, China, Japan, Southeast Asia, and Europe. Its revenue base is closely tied to capital spending by semiconductor manufacturers and outsourced assembly and test providers, making demand sensitive to industry investment cycles while also supported by long-term growth in artificial intelligence, automotive electronics, mobile devices, and high-performance computing.

The company operates as a specialized equipment and software provider rather than a chip producer. Its competitive importance comes from helping manufacturers raise yields, reduce waste, and qualify new processes more quickly. For investors, Onto Innovation represents exposure to semiconductor manufacturing complexity, particularly in inspection, metrology, and advanced packaging technologies that become more important as devices grow smaller and more integrated.
