Gan EPI Wafer ：
Due to the conflicting physical processes that take place during the epitaxial process, creating LED epitaxial wafers is complicated. Each input parameter that must be optimized is crucial to the development of the LED layers. The ideal growing circumstances for each stratum are also distinct. This is due to the fact that a number of variables, including layer thickness, composition, lingering contaminants, and interface quality, affect how well an LED performs.
A variety of partnerships and collaborations are now taking place in the LED business. These collaborations should result in fresh discoveries and broaden the industry’s reach. applications including fabrication of semiconductors, intelligent sensing, and mini/micro LED displays
Epitaxial wafers are frequently utilized in mobile devices and have a wide range of uses.

Gan EPI Wafer :
This material is appropriate for RF because it combines SiC’s outstanding thermal conductivity with GaN’s high power density and low loss characteristics. The current size is still restricted to 4 inches and 6 inches by the SiC substrate, and 8 inches has not been advocated. The majority of microwave radio frequency device manufacturing uses epitaxial GaN-on-SiC wafers.
GaN-on-Si has a low current industry production yield, but there is enormous potential for cost reduction because Si is the most developed, defect-free, and least expensive substrate material; at the same time, Si can be expanded to 8-inch wafer fabs to lower the unit production cost; as a result, the wafer cost is only 1% of that of the SiC base; the growth rate of Si is 200 to 300 times that of the SiC crystal material, and the corresponding fab equipment de The main use of GaN-on-Si epitaxial wafers is the production of power electronic devices, and large-scale epitaxy technology optimization is the current technical trend.
GaN-on-sapphire: The most common size is 4 inches, and the market share of GaN LED chips on sapphire substrates has surpassed 90%. This material is mostly employed in the LED industry.
GaN-on-GaN: Blue/green lasers, which are utilized in laser display, laser storage, laser illumination, and other sectors, are the primary application market for GaN employing homogeneous substrates.
GaN devices are separated into radio frequency devices and power electronic devices for design and production. Power electronic device products include SBD, normally-off FET, Normally-on FET, Cascode FET and other products for wireless charging, power switch, envelope tracking, inverter, converter and other markets. Radio frequency device products include PA, LNA, switches, MMICs, etc., which are oriented to base station satellite, radar, and other markets.
