IXYS Corporation is engaged in the design, development, manufacture and marketing of high-power, high-performance power semiconductors. IXYS's power semiconductors convert electricity at relatively high voltage and current levels to create efficient power as required by a specific application. The Company's power semiconductor products have historically been divided into two primary categories, power metal-oxide semiconductor transistors and bipolar products. Its power semiconductors are sold separately and are also packaged in high-power modules that frequently consist of multiple semiconductor dies. The Company also sells gallium arsenide power semiconductors, and manufactures its proprietary Direct Copper Bond substrate for use in its own power semiconductors, as well as for sale to other power semiconductor manufacturers. Additionally, the Company sells integrated circuits that have applications in power management, telecommunications and displays.
