------------------------------------------------------------------------------------------------------------------------------
GaAs wafer
Gallium arsenide (GaAs) is an excellent semiconducting material. It
has large direct band gap, high electron mobility, high frequency
low noise and high conversion efficiency) and other outstanding
advantages.
GaAs substrate is divided into conductive and semi-insulating,
widely used in laser (LD), semiconductor light-emitting diode
(LED), near infrared laser, quantum well high-power laser and high
efficiency solar panels; HEMT and HBT chips for radar, microwave,
millimeter wave or ultra-high speed computers and optical
communications; Radio frequency devices for wireless communication,
4G, 5G, satellite communication, WLAN.
Recently, gallium arsenide substrate has also made great progress
in mini-LED, Micro-LED and red light LED, which is widely used in
AR/VR wearable devices.
GaAs Wafer Market&Application
Gallium arsenide is an important semiconductor materialIt belongs
to gro up lll-V compound semiconductors and the zincblende crystal
lattice structure, with a lattice constantof5.65x10-10ma melting
point of1237° C,and a band gap of 1.4 electron volts.Gallium
arsenide can be made into semi-insulating high-resistance
materialswhich can be used to make integrated circuit
substratesinfrared detectorsgamma photon
detectors,etc.Because its electron mobility is 5to6times greater
than sili con,SI GaAs substrate has been importantly used in the
fabrication of microwave devices and high-speed digital
circuits.Semiconductor devices fabricated on gallium arsenide have
the advantages of high frequency high temperature, lowtemperature
performancelow noiseand strong rac iation resistance,which make the
GaAs substrate market enlarge.
