Santa Clara, California, based Intevac, Inc. (IVAC) manufactures thin-film disk sputtering equipment for the thin-film disk /hard disk drives (HDD) industry and develops cutting-edge technology for extreme low-light imaging sensors, cameras, and systems. The company operates in two business segments: Equipment and Imaging. The Equipment business (96% of 2006 revenue) makes, as well as services, capital equipment that deposits or sputters highly engineered thin films on to the disks used in HDD. Intevac's Equipment customers include Hitachi Global Storage Technology (HGST), Komag (acquired by Western Digital), Maxtor (acquired by Seagate), Seagate Technology, Showa Denko, and Fuji Electric. The Imaging business develops and manufactures electro-optical sensors, cameras, and systems that permit highly sensitive detection of photons in the visible and near-infrared portions of the spectrum, allowing vision in extreme low-light conditions. Though Intevac currently develops night-vision technology and equipment for both military and commercial applications, most of its Imaging revenue has historically been derived from research and development contracts funded by the U.S. government as the business is still in its early stages. The imaging business comprised 4% of 2006 revenue. During 2006, the company generated 90% of its revenue from the Asia, 10% from the United States, with a small amount, rounding to 0%, from Europe.
