Overview
Taiwan Semiconductor Company Limited, also known as Taiwan Semiconductor, Taiwan Semi, or TSC, is a Taiwanese semiconductor and electronic-components manufacturer headquartered in Xindian District, New Taipei City. It was established in January 1979 by Arthur Wang and initially concentrated on rectifier manufacturing. Over time, the company expanded from a relatively focused rectifier business into a broader supplier of discrete semiconductor devices and related electronic products. The company’s product portfolio includes trench Schottky rectifiers, MOSFETs, transient-voltage-suppression devices, transistors, analog integrated circuits, bridge rectifiers, and electrostatic-discharge protection components. These products are used in automotive systems, industrial instruments, power supplies, communications equipment, LED lighting, consumer electronics, and other applications requiring power conversion, circuit protection, switching, or signal control. Its development direction has included trench semiconductor processes, Super Junction technology, automated packaging, and devices designed for automotive and industrial environments. Taiwan Semiconductor operates manufacturing facilities in Taiwan and China. Its Taiwanese production footprint includes the Yilan facility and the Lije facility in Wujie Township. The Lije operation is associated primarily with TVS components and six-inch wafers. In China, the company operates facilities in Tianjin and Shandong. Tianjin specializes in four-inch wafers and surface-mount adhesive products, while the Shandong plant manufactures bridge rectifiers and maintains quality and environmental certifications relevant to industrial and automotive production. The company also maintains service centers in China, the United States, Germany, and Japan. A notable part of TSC’s corporate history is its earlier involvement in barcode-printing equipment. In 1991, the company invested in the United States-based Eltron Corporation, leading to production of thermal-transfer and thermal-direct barcode printers. This activity later developed into a separate business direction. In 2007, TSC established TSC Auto ID Technology Co., Ltd., and transferred its barcode-printer business unit to that subsidiary, which focused on barcode-printer development and manufacturing, including wireless RFID barcode printers. The company expanded its Chinese manufacturing presence during the 1990s by establishing Yangxin Everwell Electronic Co., Ltd. in Shandong in 1995 and Tianjin Everwell Technology Co., Ltd. in 1996. It applied for an over-the-counter listing in Taiwan in 1999 and was officially listed on the Taiwan Stock Exchange in February 2000. Public-market capital supported further automation, production-equipment expansion, and development of semiconductor products including Schottky diodes. Taiwan Semiconductor has also pursued technology and commercial collaborations. Its reported relationships include cooperation with United Microelectronics Corporation on MOSFET technologies and work with Bosch on automotive protection devices. In 2016, it acquired a TVS product line from Onsemi, strengthening its positioning in automotive and industrial-control applications. The company therefore occupies a specialized position in the global semiconductor supply chain: it is not principally identified with leading-edge logic processors, but with discrete and protection-oriented components that are integrated into a wide range of electronic systems.
History
Taiwan Semiconductor Company Limited was founded in January 1979 by Arthur Wang. Its original business was the manufacture of rectifiers, and the company was initially headquartered in what was then Tucheng Township in Taipei County, now Tucheng District. The establishment of the Yilan Plant in 1987 increased rectifier-production capacity and gave the company a larger manufacturing base in Taiwan. In 1991, Taiwan Semiconductor automated parts of its operations and began moving into mass production of additional semiconductor products, including transient-voltage-suppression devices and bridge rectifiers. The same year, it invested in Eltron Corporation in the United States. That investment led to the production of thermal-transfer and thermal-direct barcode printers, creating a second line of business alongside semiconductor manufacturing. The company began building a manufacturing presence in mainland China during the 1990s. Yangxin Everwell Electronic Co., Ltd. was established in Shandong in April 1995, followed by Tianjin Everwell Technology Co., Ltd. in August 1996. These operations broadened the company’s regional production capacity and supported supply to China’s expanding electronics market. Taiwan Semiconductor applied for an over-the-counter listing in December 1999. Its shares were officially listed on the Taiwan Stock Exchange on February 21, 2000, at NT$22 per share. The capital raised through the public-market process supported automation, new production equipment, and further development of semiconductor products, including Schottky diodes and other rectifier technologies. The Yilan Plant added a Schottky-diode chip production line in 2002. As the company increasingly emphasized diode and power-semiconductor products, it reorganized its barcode-printer activity. Investment in a dedicated business led to the establishment of TSC Auto ID Technology Co., Ltd. in 2007, and in August of that year the barcode-printer business unit was transferred to the subsidiary. TSC Auto ID subsequently focused on barcode-printer development and production, including wireless RFID barcode printers. Between 2011 and 2013, Taiwan Semiconductor implemented diode trench processes and developed Super Junction capabilities. These technology and manufacturing initiatives were intended to improve capacity and product capability for automotive, lighting, and industrial-equipment applications, with automated packaging becoming an important part of the production strategy. In 2016, the company acquired a TVS product line from Onsemi in a transaction reported at US$7.1 million. The move expanded Taiwan Semiconductor’s protection-device portfolio and supported its ambitions in automotive and industrial control. The company also reported collaborations with United Microelectronics Corporation on MOSFET technology and with Bosch on automotive protection devices. Taiwan Semiconductor’s later operating structure included manufacturing facilities in Yilan and Lije in Taiwan and in Tianjin and Shandong in China. The Lije facility focuses primarily on TVS products and six-inch wafers, Tianjin on four-inch wafers and surface-mount adhesive products, and Shandong on bridge rectifiers. The Shandong plant is reported to hold IATF 16949, ISO 9001, and ISO 14001 certifications. By 2022, the company reported quarterly and year-to-date revenue figures reflecting its continuing operation across semiconductor and related electronic-product markets.
