Fabless manufacturing is the design and sale of hardware devices and semiconductor chips while outsourcing their fabrication (or fab ) to a specialized manufacturer called a semiconductor foundry . These foundries are typically, but not exclusively, located in the United States , China , and Taiwan . Fabless companies can benefit from lower capital costs while concentrating their research and development resources on the end market. Some fabless companies and pure play foundries (like TSMC ) may offer integrated-circuit design services to third parties.
