About GaN-on-GaN GaN-on-SIC Feature Introduce


GaN epitaxial wafer: According to the different substrates, it is mainly divided into four types: GaN-on-Si, GaN-on-SiC, GaN-on-sapphire, and GaN-on-GaN.

GaN-on-Si: The current industry production yield is low, but there is a huge potential for cost reduction: because Si is the most mature, defect-free, and lowest-cost substrate material; at the same time, Si can be expanded to 8-inch wafer fabs , reduce the unit production cost, so that the wafer cost is only one percent 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 depreciation and energy consumption difference in cost, etc. GaN-on-Si epitaxial wafers are mainly used in the manufacture of power electronic devices, and the technical trend is to optimize large-scale epitaxy technology.

GaN-on-SiC: Combining the excellent thermal conductivity of SiC with the high power density and low loss capabilities of GaN, it is a suitable material for RF. Limited by the SiC substrate, the current size is still limited to 4 inches and 6 inches, and 8 inches has not been promoted. GaN-on-SiC epitaxial wafers are mainly used to manufacture microwave radio frequency devices.

GaN-on-sapphire: Mainly used in the LED market, the mainstream size is 4 inches, and the market share of GaN LED chips on sapphire substrates has reached more than 90%.


GaN-on-GaN: The main application market of GaN using homogenous substrates is blue/green lasers, which are used in laser display, laser storage, laser lighting and other fields.

GaN device design and manufacturing: GaN devices are divided into radio frequency devices and power electronic devices. Radio frequency device products include PA, LNA, switches, MMICs, etc., which are oriented to base station satellite, radar and other markets; 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.
According to the process, it is divided into two categories: HEMT, HBT radio frequency process and SBD, PowerFET power electronic device process.
