About AXT

AXT is a material science company that develops and manufactures high-performance wafer substrates, including indium phosphide (InP), gallium arsenide (GaAs), and germanium (Ge). These substrates are used when traditional silicon substrates do not meet the performance requirements of semiconductor or optoelectronic devices. The company is headquartered in Fremont, California, with a Chinese subsidiary (Tongmei) and manufacturing facilities, and operates a global supply chain through partnerships in Asia.
