History
[edit]Rudolph Research: 1940–1995
[edit]Rudolph Technologies, Inc. (RTI) traces its origins to 1940, when Otto Curt Rudolph formed O.C. Rudolph & Sons, Inc.[2] Originally an importer of microscopes and scientific instruments, this RTI predecessor was renamed in October 1970 to Rudolph Research Corporation. The company designed optical equipment for laboratories and universities.
The company Otto Rudolph established continued to evolve, making breakthroughs in ellipsometry including the first production-oriented ellipsometer for thin, transparent film measurements. The company continued development of its metrology products, securing new patents along the way.
Nanometrics: 1975–2019
[edit]Nanometrics was founded in 1975 and was a pioneer and innovator in the field of optical metrology. In 1984, the company started publicly trading.
Formation of Rudolph Technologies: 1996–1999
[edit]In June 1996, Richard Spanier, Ph.D., chief executive officer of Rudolph Research, forged a partnership agreement with Boston-based Riverside Partners[3] and New York-based Liberty Partners [4] who, along with others, invested in the company. At that time, Dr. Spanier retired his active role in the company and semiconductor industry veteran Paul F. McLaughlin was named as CEO. In August 1999, the name of the company was changed to Rudolph Technologies, Inc.
In November 1999, RTI made its initial public offering of common stock. Revenues grew dramatically, reaching a record $38.1 million. A new facility opened early in the year, and the company launched a new product, the MetaPULSE® line of copper film measurement tools.
Rudolph Technologies: 2000–2019
[edit]In July 2002, RTI agreed to acquire the Richardson, Texas-based defect control company ISOA, Inc. A spin-off from Texas Tech University's International Center for Informatics Research, ISOA had been licensing technology to the semiconductor industry for about 16 years, offering defect detection software. The deal was completed in September, with ISOA becoming RTI's Yield Metrology Group.
Several months later, RTI expanded into China by establishing an office in Shanghai's Pudong industrial area. In subsequent years, the company established additional offices in all semiconductor manufacturing regions of the world including Japan, Europe, South Korea, Taiwan and Singapore.
In 2006, a merger was completed with Minnesota-based August Technology Corporation, growing Rudolph's workforce to 550 employees. This acquisition brought Rudolph into the ‘back-end’ of the manufacturing process.
In 2007, the company acquired the semiconductor business of Washington-based Applied Precision LLC, adding probe card test and analysis to the company's portfolio. The acquisition of RVSI Inspection LLC and its Wafer Scanner inspection system was announced in 2008. Adventa Control Technologies, Inc., a provider of process control software, was acquired in 2009, and an acquisition of MKS Instruments, Inc.’s Yield Dynamics business was completed in 2010. Rudolph announced two acquisitions in 2012. NanoPhotonics GmbH, Mainz, Germany (unpatterned wafer inspection); and Azores Corp., Wilmington, MA (Rudolph's entry into the advanced packaging and FPD lithography markets). In 2013 Rudolph announced the acquisition of selected assets of Tamar Technology, Newbury Park, CA, a supplier of 3D metrology technologies. Rudolph acquired the inspection technology of Stella Alliance in 2015, adding patents to enhance its inspection capability which was a major disaster.
In November 2015, Rudolph announced the retirement of Paul F. McLaughlin and appointment of Michael P. Plisinski as CEO and Director.[5]
As of January 19, 2017, Rudolph Technologies Inc. had a market capitalization of about $713 million.[6]
In January 2017, Voce Capital Management LLC in a letter to investors, urged merging semiconductor-equipment makers Rudolph Technologies Inc. and Nanometrics Inc.[6] The merger eventually occurred and closed on October 30, 2019.[7] According to the Joint Proxy Statement announcing the terms of the merger, talks began in the first quarter of 2016 and continuing into 2017, Nanometrics and Rudolph engaged in discussions concerning a potential business combination between the two companies, to be structured as a merger of equals transaction, which discussions between the parties are referred to as the 2017 discussions. In connection with the 2017 discussions, in February 2016, Nanometrics and Rudolph entered into a mutual confidentiality agreement, which was subsequently extended in January 2017.[8]
On October 25, 2019, Rudolph merged with Nanometrics Incorporated to become Onto Innovation, trading as NYSE: ONTO.[7]
The company is now headquartered in Wilmington, Massachusetts, with additional U.S. operations in New Jersey, Minnesota, California, Texas, Oregon and Washington. Manufacturing operations for inspection and some metrology products are consolidated in Minnesota; most metrology manufacturing operations is in California; stepper manufacturing is located in Wilmington, Massachusetts.
Products and services
[edit]Semiconductor fabrication, packaging and testing
[edit]Semiconductor device fabrication is the process used to create the integrated circuits that are found in commonly used electronic devices and electrical equipment. It is a multiple-step process during which electronic circuits are gradually built by adding elements and layers of material on a substrate made of pure silicon, or various compounds in the case of specialized applications, hundreds of steps performed by specialized process tools are required before the wafer moves to a final packaging facility.
The focus of packaging and assembly is to ensure an electrical connection from the die to the circuit board, to encapsulate the package for mechanical integrity and to withstand thermal variations. The era of slim form-factor devices, such as smart phones, implies high level of functionality in very dense footprint. Due to these requirements, the challenges in packaging, assembly and test have significantly increased and advanced packaging techniques such as bumping or through-silicon via are necessary.
JetStep
[edit]Onto Innovation has sold multiple JetStep-branded projection lithography steppers. JetStep supports large-panel format lithography.[9]
Rudolph Technologies, a predecessor to Onto Innovation, described its JetStep system as being suitable for wafers up to 450mm and rectangular panels up to Gen 3.5 size (720mm x 600mm).[10]

History
Origins of Predecessor Companies
O.C. Rudolph & Sons, Inc. was founded in 1930 by Otto Curt Rudolph as an importer of microscopes and scientific instruments, initially focusing on distributing optical equipment for research and industrial applications.[12] During and after World War II, the company began custom designing and manufacturing optical instrumentation, including manual polarimeters and saccharimeters.[12] In the postwar era, Rudolph began applying these technologies to emerging needs in semiconductor quality control, where accurate characterization of material properties became essential for manufacturing processes.[12] In October 1970, the company was renamed Rudolph Research Corporation to reflect its growing emphasis on research-oriented instrumentation.[12] Rudolph Research advanced optical metrology through the development of ellipsometers, non-destructive tools that measure thin-film thickness and refractive index using polarized light, with applications in semiconductor thin-film analysis.[12] The company's spectroscopic ellipsometer gained widespread adoption in the integrated circuit industry for precise angstrom-level film measurements, supporting quality control in semiconductor fabrication.[12] These innovations established Rudolph Research as a key provider of optical metrology solutions during the rapid expansion of the semiconductor sector in the postwar era. Nanometrics was founded in 1975 by Vincent J. Coates to commercialize spectroscopic optical measurement technologies, initially targeting film thickness measurements in semiconductor manufacturing.[13] The company introduced its first product, the NanoSpec, in 1977—a spectroscopic reflectometer for non-contact thin-film metrology, enabling precise optical critical dimension and thickness assessments without physical contact.[13] Nanometrics went public on NASDAQ in 1984 under the ticker NANO, which provided capital for expanding its portfolio of non-contact metrology tools focused on semiconductor process control.[14] Over the following decades, Nanometrics achieved key milestones in automated optical systems, including the development of integrated metrology platforms in the 1990s for real-time film thickness and critical dimension monitoring in wafer fabrication.[13] By the 2000s, the company advanced optical critical dimension (OCD) metrology using ellipsometry and reflectometry to measure complex device structures, supporting advanced nodes in semiconductor production.[13] Through 2019, Nanometrics continued innovating in automated systems for 3D metrology and overlay control, enhancing process yields in high-volume semiconductor manufacturing environments.[13]Formation and Early Growth of Rudolph Technologies
Rudolph Technologies was established in June 1996 through a spin-off of the metrology division from its predecessor, Rudolph Research Corporation, which had a legacy in ellipsometry instrumentation dating back to 1930. The transaction involved a sale to a group of investors led by Riverside Partners and Liberty Partners, providing capital to focus on advanced semiconductor process control tools. Paul F. McLaughlin was appointed as the company's first CEO at that time, guiding its strategic direction toward thin-film metrology and yield enhancement solutions for the semiconductor industry.[15] In its early years, Rudolph Technologies prioritized product development to address emerging needs in semiconductor manufacturing, particularly for copper interconnect processes. A key launch was the MetaPULSE® system in 1998, a non-contact thin-film metrology tool designed for measuring metal thicknesses in copper electroplating applications, enabling precise process control to improve device yields. This product established Rudolph's initial product lines in advanced packaging metrology, complementing its focus on optical metrology techniques to enhance semiconductor fabrication efficiency. The company emphasized tools that supported yield improvement by detecting and measuring critical process variations at the wafer level.[16] Rudolph Technologies went public on November 12, 1999, with an initial public offering on NASDAQ under the ticker RTEC, raising approximately $70 million in proceeds to fuel expansion and repay debts. The IPO marked a significant milestone, with the company's first full-year revenue reaching $38.1 million, driven by adoption of its metrology systems in high-volume semiconductor production. Organizationally, the company relocated its headquarters to Flanders, New Jersey, in 1999, centralizing operations to support growing demand for its semiconductor yield enhancement tools.
