(GaAs) Gallium Arsenide Wafers
PWAM 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.
