Gallium nitride (GaN) is a semiconductor compound used to make devices that provide high output power with small physical volume, and high efficiency at ultra-high and microwave radio frequencies. Power devices are being optimized since energy saving is becoming a top priority due to the depletion of oil sources and with limited sources of energy. Two major contributors for losses in power devices are conduction losses and switching losses; however, these losses are being minimized using (GaN) gallium nitride devices which possess high breakdown voltage and low conduction resistance characteristics, thus driving its demand. Also, it has led to the growth of gallium nitride semiconductor devices especially for high efficiency power supplies in server and other IT equipment and in the rapidly expanding hybrid electric vehicles and electric vehicles. The process of manufacturing gallium nitride semiconductor devices involve growing a GaN crystal or wafer on which transistors and integrated circuits (ICs) can be fabricated.
The major driver for growth of the gallium nitride semiconductor device market includes growing demand for low costs and power consumption in consumer electronics and automotive markets, wide variety of properties associated with GaN material is encouraging innovative applications, also realization of GaN in RF Power electronics, and growing demand of gallium nitride (GaN) RF semiconductor devices especially in defense, military, and aerospace applications. However the major restraint affecting the growth of the gallium nitride semiconductor device market is high costs associated with it and growing opposition from silicon carbide (SiC) devices in high voltage semiconductor applications. Also, the growing interest in implementation of 5G infrastructure and demand for electric and hybrid vehicles globally is creating considerable opportunities for the global gallium nitride semiconductor device market.
