3inch GaAs substrates, GaAs wafer for led,Gallium Arsenide crystal Wafers,Si/Zn Dopant GaAs wafer
(A compound of the elements gallium and arsenic. It is a III-V direct bandgap semiconductor with a zinc blende crystal structure)
--------------------------------------------------------------------------------------------------------------
GaAs) Gallium Arsenide Wafers
we develops and manufactures compound semiconductor substrates
the factory has used advanced crystal growth technology,vertical gradient freeze(VGF) and GaAs wafer processing technology,established a production line from crystal growth, cutting, grinding to polishing processing and built a 100-class clean room for wafer cleaning and packaging.
Our GaAs wafer include 2~6 inch ingot/wafers for LED,LD and Microelectronics applications.
We are always dedicated to improve the quality of currently substates and develop large size substrates.
Application:
1. Mainly used in electronics, low temperature alloys, Gallium Arsenide.
2. The primary chemical compound of gallium in electronics, is used in microwave circuits, high-speed switching circuits, and infrared circuits.
3. Gallium Nitride and Indium Gallium Nitride, for semiconductor uses, produce blue and violet light-emitting diodes (LEDs) and diode lasers.
