Companies in this industry make semiconductors (computer chips) and other components used in electronic devices. Major companies include Intel, Micron Technology, and Qualcomm (all based in the US), along with Broadcom (Singapore), Samsung Electronics (South Korea), Taiwan Semiconductor Manufacturing Company, and Toshiba (Japan).
The industry depends highly on demand from the computer industry and makers of telecommunications products such as cell phones, which can vary sharply from year to year. Companies can be successful producing standard parts at low cost or by producing highly specialized components. Small companies can compete effectively with large ones by producing specialized products or developing new applications. Technological expertise is extremely important. The US industry is concentrated: the 50 largest companies generate about 60% of revenue.
