Freestanding GaN substrate

Product Description

Freestanding GaN substrate

As a leading GaN substrate supplier, PAM-XIAMEN has established the manufacturing technology for freestanding (Gallium Nitride)GaN substrate wafer  which is Bulk GaN substrate for UHB-LED, LD and fabrication as MOS-based devices. Grown by hydride vapour phase epitaxy (HVPE) technology, our GaN substrate for III-nitride devices has  low defect density and less or free macro defect density. The GaN substrate thickness is 330~530μm.

In addition to power devices, gallium nitride semiconductor substrates are increasingly used in the manufacture of white light LEDs because the GaN LED substrates provide improved electrical characteristics and their performance exceeds current devices. Moreover, the rapid development of gallium nitride substrate technology has led to the development of high-efficiency GaN free standing substrates with low defect density and free macro defect density. Therefore, such GaN substrates can be increasingly used to white LEDs. As a result, the bulk GaN substrate market is growing rapidly. By the way, bulk GaN wafer can be used for testing vertical power device concepts.

Application of GaN Substrate

Solid State Lighting:GaN devices are used as ultra high brightness light emitting diodes (LEDs), TVs, automobiles, and general lighting  

DVD Storage: Blue laser diodes

Power Device: Devices fabricated on GaN bulk substrate are used as various components in high-power and high-frequency power electronics like cellular base stations, satellites, power amplifiers, and inverters/converters for electric vehicles (EV) and hybrid electric vehicles (HEV). GaN’s low sensitivity to ionizing radiation (like other group III nitrides) makes it a suitable material for spaceborne applications such as solar cell arrays for satellites and high-power, high-frequency devices for communication, weather, and surveillance satellites

Pure Gallium Nitride Substrate Ideal for III-Nitrides re-growth

Solar Cells: GaN’s wide band gap covers the solar spectrum from 0.65 eV to 3.4 eV (which is practically the entire solar spectrum), making indium gallium nitride

(InGaN) alloys perfect for creating solar cell material. Because of this advantage, InGaN solar cells grown on GaN substrates are poised to become one of the most important    new applications and growth market for GaN substrate wafers.

Ideal for HEMTs, FETs

GaN Schottky diode project: We accept custom spec of Schottky diodes fabricated on the HVPE-grown, free-standing gallium nitride (GaN) layers of n- and p-types.

Both contacts (ohmic and Schottky) were deposited on the top surface using Al/Ti and Pd/Ti/Au.

Remark：
The Chinese government has announced new limits on the exportation of Gallium materials (such as GaAs, GaN, Ga2O3, GaP, InGaAs, and GaSb) and Germanium materials used to make semiconductor chips. Starting from August 1, 2023, exporting these materials is only allowed if we obtains a license from the Chinese Ministry of Commerce. Hope for your understanding and cooperation!
