Semi-Insulating, GaAs Substrate, 2”, Mechanical Grade

PAM-XIAMEN Develops and manufactures compound semiconductor substrates-gallium arsenide crystal and wafer. We has used advanced crystal growth technology, vertical gradient freeze(VGF) and (GaAs)Gallium Arsenide wafer processing technology. The required electrical properties are obtained by adding dopants such as silicon or zinc. The result is n-type or p-type high-resistance (>10^7 ohm.cm) or low-resistance (<10 - 2 ohm.cm) semiconductors. The wafer surfaces are generally epi-ready (extremely low contamination) i.e. their quality is suitable for direct use in epitaxial processes.

Properties of GaAs Crystal

What is GaAs wafer?

Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is a III-V direct band gap semiconductor with a zinc blende crystal structure.

GaAs wafer is an important semiconducor material. It belongs to group III-V compound semiconductor. It is a sphalerite type lattice structure with a lattice constant of 5.65x 10-10m, a melting point of 1237 ℃ and a band gap of 1.4 EV. Gallium arsenide can be made into semi insulating high resistance materials with resistivity higher than silicon and germanium by more than three orders of magnitude, which can be used to make integrated circuit substrate, infrared detector, γ photon detector, etc. Because its electron mobility is 5-6 times larger than that of silicon, it has been widely used in microwave devices and high-speed digital circuits. The semiconductor device made of GaAs has the advantages of high frequency, high temperature and low temperature, low noise and strong radiation resistance. In addition, it can also be used to make bulk effect devices.
