AXT

AXT is a worldwide materials science company that develops and produces high-performance compound and single element semiconductor substrates (wafers), including indium phosphide, gallium arsenide, and germanium substrates, along with certain raw materials used in substrate manufacturing. It sells its substrate wafers and raw materials to companies that apply epitaxial layers, wafer fabs, chip design companies, LED manufacturers, universities and research organizations, positioning itself at the beginning of the semiconductor supply chain rather than designing or manufacturing chips itself.
