Xiamen Powerway Advanced Material Co., Ltd.

Before 1990, we are stated owned condensed matter physics research center. We are stated owned condensed matter physics research center. In 1990, center launched Xiamen Powerway Advanced Material Co., Ltd (PAM-XIAMEN), now it is a leading manufacturer of compound semiconductor material in China. We have owns and shares four modern factories, which can provide quite a big range of qualified products to meet different needs of our customers. Commercial CdZnTe (CZT) wafer are on mass production,which is a new semiconductor, which enables to convert radiation to electron effectively, it is mainly used in infrared thin-film epitaxy substrate, X-ray and γ-ray detection, laser optical modulation, high-performance solar cells and other high-tech fields. PAM-XIAMEN has established the manufacturing technology for GaN epitaxy on Sapphire and freestanding GaN single crystal wafer substrate which is for UHB-LED and LD. 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. PAM-XIAMEN has developed SiC crystal growth technology and SiC wafer processing technology, established a production line to manufacturer SiC substrate of polytype 4H and 6H in different quality grades for researcher and industry manufacturers,Which is applied in GaN epitaxy device,power devices, high-temperature device and optoelectronic Devices.As a professional company invested by the leading manufacturers from the fields of advanced and high-tech material research and state institutes and China’s Semiconductor Lab,we are devoted to continuously improve the quality of currently substates and develop large size substrates, as well as epitaxial technology.
