ONTO INNOVATION INC.

Onto Innovation® designs, develops, manufactures, and supports metrology and inspection tools for the semiconductor industry. The company provides process control tools for optical metrology and inspection on patterned and unpatterned wafers, including macro defect inspection of both 2D and 3D wafer features, wafer substrate and panel substrate lithography systems, and process control analytical software. Its products are primarily used by silicon wafer manufacturers, semiconductor integrated circuit ("IC") fabricators, and advanced packaging manufacturers in the semiconductor market. Products are also used for process control in specialty device manufacturing markets such as light emitting diodes ("LED"), vertical-cavity surface-emitting lasers ("VCSEL"), micro-electromechanical systems ("MEMS"), CMOS image sensors ("CIS"), silicon and compound semiconductor (SiC and GaN) power devices, analog devices, RF filters, data storage, and certain industrial and scientific applications. Onto Innovation provides process and yield management solutions for bare silicon wafer production and wafer processing facilities ("front-end" manufacturing), and advanced packaging of chips and test facilities ("back-end" manufacturing). This is achieved through a portfolio of standalone systems for optical metrology, macro-defect inspection, packaging lithography, and transparent and opaque thin film measurements. The company's automated and integrated metrology systems measure critical dimensions, device structures, topography, shape, various thin film compositions (including three-dimensional features and film thickness), and optical and material properties. Its focus areas include products that provide yield-enhancing and actionable information for microelectronic device manufacturers. Systems feature sophisticated software and production-worthy automation. The advanced process control software portfolio includes solutions for standalone tools, groups of tools, and factory-wide and enterprise-wide suites. The systems are supported by worldwide customer service and applications support.
