Onto Innovation

Onto Innovation Inc. is a semiconductor equipment and process-control company headquartered in Wilmington, Massachusetts. The company was created in 2019 through the combination of Rudolph Technologies, Inc. and Nanometrics Incorporated, bringing together complementary capabilities in optical metrology, inspection, lithography, process control and manufacturing analytics. It serves semiconductor manufacturers and other microelectronics producers whose fabrication and packaging processes require precise measurement and defect detection. The company’s technology portfolio addresses several stages of semiconductor production. Its systems are used to assess unpatterned wafer quality, measure thin films and critical dimensions, inspect wafers and packages for defects, analyze metal interconnect composition, and provide software for yield management and factory analytics. Onto also supplies lithography solutions for advanced semiconductor packaging, a field that has become increasingly important as chipmakers use technologies such as wafer-level packaging, bumping and through-silicon vias to increase functionality within smaller physical footprints. Onto’s heritage combines two established technology lineages. Rudolph Research originated in 1940 as O.C. Rudolph & Sons, an importer of microscopes and scientific instruments founded by Otto Curt Rudolph. It later developed optical laboratory equipment and semiconductor metrology products, including production-oriented ellipsometry tools for measuring transparent thin films. After investment and management changes in the 1990s, the business became Rudolph Technologies, Inc. and expanded through acquisitions into wafer inspection, yield metrology, process-control software, probe-card analysis, three-dimensional metrology, unpatterned-wafer inspection and advanced-packaging lithography. Nanometrics was founded in 1975 and developed a separate reputation as an innovator in optical metrology. It became publicly traded in 1984. Rudolph and Nanometrics held discussions about a potential combination during the 2016–2017 period, and the companies ultimately completed their merger on October 30, 2019. The combined company adopted the Onto Innovation name and trades on the New York Stock Exchange under the symbol ONTO. Onto operates in the major global semiconductor manufacturing regions and maintains additional United States operations in New Jersey, Minnesota, California, Texas, Oregon and Washington. Its customers use the company’s instruments and software to improve process control, identify defects, monitor materials and dimensions, and increase manufacturing yield. The company’s business is therefore positioned as an enabling infrastructure supplier rather than a consumer-facing chip or electronics brand. Its competitive relevance comes from combining measurement hardware, inspection, lithography and data-driven process-management capabilities across both front-end wafer fabrication and back-end assembly and packaging.

Onto Innovation’s corporate history is rooted in the development of two semiconductor process-control businesses: Rudolph Technologies and Nanometrics. The Rudolph lineage began in 1940, when Otto Curt Rudolph established O.C. Rudolph & Sons, Inc. The original business imported microscopes and scientific instruments before evolving into a developer of optical equipment for laboratories and universities. In October 1970 it was renamed Rudolph Research Corporation. The company developed expertise in ellipsometry and related optical measurement methods, including an early production-oriented ellipsometer designed to measure transparent thin films. These capabilities later became relevant to semiconductor manufacturing, where controlling the thickness and composition of deposited layers is essential. In June 1996, Rudolph Research chief executive Richard Spanier formed an investment partnership involving Riverside Partners, Liberty Partners and other investors. Spanier retired from active management, and semiconductor-industry veteran Paul F. McLaughlin became chief executive. The company changed its name to Rudolph Technologies, Inc. in August 1999 and completed an initial public offering in November of that year. Around this period, it introduced the MetaPULSE line of copper-film measurement tools and expanded its manufacturing capacity. Rudolph Technologies then broadened its capabilities through a series of acquisitions. In 2002 it acquired ISOA, a Richardson, Texas-based defect-control business whose technology was incorporated into Rudolph’s Yield Metrology Group. The company also began building an international presence, opening an office in Shanghai and later establishing operations in Japan, Europe, South Korea, Taiwan and Singapore. Its 2006 merger with August Technology expanded its workforce and added capabilities associated with the back-end portion of semiconductor manufacturing. In 2007, Rudolph acquired the semiconductor business of Applied Precision, adding probe-card test and analysis. Further transactions brought in wafer inspection, process-control software, yield-management technology, unpatterned-wafer inspection, three-dimensional metrology and lithography for advanced packaging. Among the later additions were RVSI Inspection’s wafer-scanner technology in 2008, Adventa Control Technologies in 2009, MKS Instruments’ Yield Dynamics business in 2010, NanoPhotonics GmbH and Azores Corp. in 2012, selected assets of Tamar Technology in 2013, and inspection technology from Stella Alliance in 2015. These transactions helped Rudolph move beyond individual measurement instruments toward a broader process-control platform covering fabrication, inspection, packaging and manufacturing analytics. Nanometrics followed a separate path. Founded in 1975, it became known for optical metrology and related semiconductor measurement technologies. The company began trading publicly in 1984. Rudolph and Nanometrics discussed a possible combination during 2016 and 2017, including a mutual confidentiality agreement first signed in 2016 and extended in 2017. The discussions eventually led to a merger structured as a combination of equals. The merger closed on October 30, 2019, and the resulting company became Onto Innovation. It retained a public listing on the New York Stock Exchange under the ticker ONTO. The new organization combined Rudolph’s broader inspection, lithography and process-control portfolio with Nanometrics’ optical-metrology heritage. Onto Innovation is headquartered in Wilmington, Massachusetts, with additional United States operations in New Jersey, Minnesota, California, Texas, Oregon and Washington, as well as customer and support activity across important international semiconductor-manufacturing regions. Today, Onto Innovation supplies equipment and software used to monitor semiconductor wafers, devices and packages. Its scope includes unpatterned-wafer quality, nanoscale-to-large-die three-dimensional metrology, macro defect inspection, metal-interconnect analysis, factory analytics and advanced-packaging lithography. The company’s historical development reflects the semiconductor industry’s movement toward tighter process tolerances, more complex packaging and greater reliance on integrated inspection and manufacturing data.
