Semi-Insulating , GaAs Wafer With Low Defect Density , 3”, Prime Grade

Semi-Insulating , GaAs Wafer With Low Defect Density , 3”, Prime 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 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.

What is a GaAs Test Wafer?

Most GaAs test wafers are wafers which have fallen out of prime specifications. Test wafers may be used to run marathons, test equipment and for high-end R & D. They are often a cost-effective alternative to prime wafers.
