Produktbeskrivning

GaN Template (gallium nitride template)

PAM-XIAMEN’s GaN Template consists of crystalline layers of gallium nitride (GaN), aluminum nitride (AlN), aluminum gallium nitride (AlGaN) and indium gallium nitride (InGaN), which are epilayer on sapphire and electronic grade for fabrication as MOS-based devices. PAM-XIAMEN’s Gallium Nitride Template Products enable 20-50% shorter epitaxy cycle times and higher quality epitaxial device layers, with better structural quality and higher thermal conductivity,which can improve devices in the cost, yield, and performance.

Hydride Vapour Phase Epitaxy (HVPE) process

GaN template on sapphire is grown by HVPE process and technology for the production of compound semiconductors such as GaN, AlN, and AlGaN. GaN templates are used in a wide applications: nanowire growth, solid state lighting, short wavelength optoelectronics and RF power device.

In the HVPE process, Group III nitrides (such as GaN, AlN) are formed by reacting hot gaseous metal chlorides (such as GaCl or AlCl) with ammonia gas (NH3). The metal chlorides are generated by passing hot HCl gas over the hot Group III metals. All reactions are done in a temperature controlled quartz furnace.

 

Anmärkning:
Den kinesiska regeringen har aviserat nya gränser för export av galliummaterial (som GaAs, GaN, Ga2O3, GaP, InGaAs och GaSb) och germaniummaterial som används för att tillverka halvledarchips. Från och med den 1 augusti 2023 är export av detta material endast tillåtet om vi får en licens från det kinesiska handelsministeriet. Hoppas på er förståelse och samarbete!
