PWAM specializes in researching and supplying semiconductor material, especially for SiC wafer,in the end of 2004,we 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.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.CdZnTe (CZT) 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 ?-ray detection, laser optical modulation, high-performance solar cells and other high-tech fields. From 2001, PWAM offers commercial CZT wafers with high quality and very competitive price.
