LEDs as a business are growing rapidly in China, spurring purchase of the high-unit-cost capital equipment needed for LED fabrication.Due to the aggressive expansion plans of some Chinese LED companies, 220 metal-organic chemical-vapor-deposition (MOCVD) gallium nitride (GaN) reactors will be installed in 2015, according to the latest data in the IHS LED Intelligence Service.
For this reason, power electronics often use nitride-based semiconductors, such as gallium nitride, which have a very high breakdown field and can be epitaxially grown to create multilayered semiconductors. Different polymorphs of gallium oxide can be grown in a MOCVD chamber by controlling the flow of hydrogen chloride.
