Segment Reporting [Abstract] |
Business Segments | Business Segments Our three reportable segments are as follows: Solar - We supply thermal processing systems, including diffusion, plasma-enhanced chemical vapor deposition (“PECVD”), atomic layer deposition (“ALD”), and related automation, parts and services, to the solar/photovoltaic industry. Semiconductor - We supply thermal processing equipment, including solder reflow equipment and related controls and diffusion for use by leading semiconductor manufacturers, and in electronics assembly for automotive and other industries. Polishing - We produce consumables and machinery for lapping (fine abrading) and polishing of materials, such as silicon wafers for semiconductor products, sapphire substrates for LED lighting and mobile devices, compound substrates, like silicon carbide wafers, for LED and power device applications, various glass and silica components for 3D image transmission, quartz and ceramic components for telecommunications devices, medical device components and optical and photonics applications.
