FEI Company (Field Electron and Ion Company, FEI) is an American company that designs, manufactures, and supports microscope technology. Headquartered in Hillsboro, Oregon, FEI has over 2,800 employees and sales and service operations in more than 50 countries around the world. Formerly listed on the NASDAQ, it is a subsidiary of Thermo Fisher Scientific. The FEI company was founded in 1971 as Field Electron and Ion Company by Dr. Lynwood W. Swanson, Mr. Noel A. Martin and Mr. Lloyd Swenson, as a supplier of electron and ion beam sources for field emission research and electron microscopy. The name was shortened to FEI Company in 1973. In 1978, Dr. J.H. Orloff, a research specialist in electrostatic optics for field emission ion and electron sources, joined the company as its fourth partner. Swanson was a professor of applied physics at the Oregon Graduate Center, and Orloff's doctoral adviser. FEI's introduction of the liquid metal ion source in 1981 led to its application in the semiconductor industry for mask repair and defect analysis. The current company was formed by the 1997 merger between FEI and Philips Electron Optics, and the 1999 acquisition of ion beam company Micrion. As such, the company can trace its roots in electron microscopy to the early commercial instruments produced by Philips Electron Optics in the 1940s. More information...
