Rubicon Technology, Inc. designs, manufactures and distributes sapphire substrates for the global semiconductor, optoelectronics and industrial markets. The company’s primary products include high‐quality sapphire wafers and specialty sapphire products used in light‐emitting diode (LED) manufacturing, radio frequency (RF) and microwave devices, data storage, and optical communications. Rubicon’s substrates serve as the foundational platform for epitaxial growth of compound semiconductor layers, addressing stringent requirements for material purity, surface quality and crystal orientation.
Rubicon’s manufacturing processes combine proprietary crystal growth techniques with precision wafer slicing and polishing to deliver sapphire substrates in a range of diameters and thicknesses. The company offers turnkey solutions from crystal ingot production through wafer fabrication, ensuring tight control over defect density, bow and total thickness variation. In addition to standard sapphire wafers, Rubicon supplies custom‐engineered components for laser optics, microwave windows and specialized industrial applications that demand high mechanical strength and optical transmission.
Headquartered in California with its primary production facility in Moses Lake, Washington, Rubicon Technology maintains a global footprint to support a diverse customer base. The company has sales offices and technical service centers across Asia—including Taiwan, China, Japan and South Korea—as well as support infrastructure in Europe. This international presence allows Rubicon to collaborate closely with LED and semiconductor manufacturers throughout key supply chain hubs and respond rapidly to evolving market requirements.
Founded in 2001 as a materials‐science spin‐off, Rubicon Technology completed its initial public offering in 2013. The company is guided by a leadership team of experienced executives in crystal growth, materials engineering and advanced manufacturing. Under their direction, Rubicon continues to invest in R&D and capacity expansions aimed at improving yield, lowering production costs and extending the performance envelope of sapphire materials for next‐generation electronic and photonic devices.
