K 465 i HP MOCVD Reactor

The Veeco K 465 i HP is a metal organic chemical vapor deposition (MOCVD) reactor. The K 465 i HP belongs to the deposition equipment category.^[1][2]

MOCVD reactors deliver metalorganic precursor vapors and hydride source gases into a heated reaction chamber. The precursor vapors decompose at the heated substrate surface and form a crystalline film. Film composition and doping are controlled by gas flow rates, chamber pressure, and substrate temperature.

MOCVD systems use a temperature-controlled susceptor to hold the substrate. Gas-distribution components at the chamber inlet spread reactants evenly across the wafer surface. A reactor of this kind also includes exhaust and pressure-control hardware that maintains the growth environment.

MOCVD is an epitaxial deposition step used in the front end of semiconductor wafer fabrication. The process follows substrate cleaning and precedes patterning, contact formation, and other device-processing steps in compound semiconductor manufacturing.

In a typical wafer-flow sequence, substrates are loaded into the reactor, brought to process temperature, exposed to controlled precursor flows, and cooled before unloading. MOCVD processing is especially suitable where controlled multilayer and doped-layer structures are required.

MOCVD reactors are applied to compound semiconductor film growth in optoelectronic and high-frequency electronic device manufacturing. Application areas include light-emitting diodes, laser diodes, photodetectors, and photovoltaic cells.

The MOCVD process supports III-V materials, including gallium arsenide and gallium nitride families. The process allows precise alloy composition, doping control, and abrupt heterointerfaces in multilayer device structures.
