Taiwan Semiconductor Manufacturing Company Limited

is a Taiwanese multinational semiconductor contract manufacturing and design company. Headquartered in Hsinchu Science Park, it is one of the world's largest non-US companies by market capitalisation. It holds a commanding majority in the semiconductor foundry market, accounting for approximately 70% of the global market share. As the leading dedicated contract chipmaker, it serves as the main supplier for Nvidia, Apple, Broadcom, and Qualcomm. The company has grown rapidly due to the artificial intelligence boom and its importance in the creation of advanced chips needed for AI. Its role as a supply chain bottleneck raises concerns that a disruption could cause another worldwide chip shortage. Although the government of the Republic of China is the largest individual shareholder, the majority of TSMC is owned by foreign investors. In 2025, the company was ranked 38th in the Forbes Global 2000. Taiwan's exports of integrated circuits amounted to $184 billion in 2022, nearly 25 percent of Taiwan's GDP. TSMC constitutes about 30 percent of the Taiwan Stock Exchange's main index. TSMC was established in 1987 as a joint venture between Taiwan’s government, the Industrial Technology Research Institute (ITRI), and private investors. Morris Chang founded the company to commercialise semiconductor research originally developed at ITRI, becoming the world’s first dedicated semiconductor foundry.
