Taiwan Semiconductor Manufacturing Company Limited
Taiwan Semiconductor Manufacturing Company Limited, together with its subsidiaries, manufactures, packages, tests, and sells integrated circuits and other semiconductor devices in Taiwan, China, Europe, the Middle East, Africa, Japan, the United States, and internationally. It provides various wafer fabrication processes, such as processes to manufacture complementary metal- oxide-semiconductor (CMOS) logic, mixed-signal, radio frequency, embedded memory, bipolar CMOS mixed-signal, and others. The company also involved in providing customer and engineering support services; manufacturing of masks; investment in technology start-up companies; research, designing, developing, manufacturing, packaging, testing, and sale of color filters; and investment activities. Its products are used in high performance computing, smartphones, Internet of things, automotive, and digital consumer electronics. Taiwan Semiconductor Manufacturing Company Limited was incorporated in 1987 and is headquartered in Hsinchu City, Taiwan.
What does it do?
TSMC is the world's most important chip factory. When Apple designs a new iPhone processor, or Nvidia designs an AI chip, they don't build it themselves — they send the blueprints to TSMC, who physically manufactures it. Think of TSMC as the world's most advanced printing press, but instead of printing books, it prints the microscopic circuits inside almost every premium electronic device you own. Without TSMC, companies like Apple, Nvidia, AMD, and Qualcomm simply could not make their products.
The AI boom has created an almost insatiable demand for advanced chips, and TSMC is the only company on the planet that can manufacture the most cutting-edge ones at scale. Nvidia's AI chips — the ones powering ChatGPT and every major AI data center — are made exclusively by TSMC. This puts TSMC at the absolute center of the most important technology trend of the decade, making it one of the most strategically critical companies in the world.
How does it make money?
TSMC charges customers a fee to fabricate wafers — the silicon discs that get sliced into individual chips. More advanced manufacturing processes (measured in nanometers; smaller = more powerful and efficient) command significantly higher prices. Revenue jumped from roughly $2.9 trillion TWD to $3.8 trillion TWD in the latest year, a 32% increase, driven almost entirely by surging demand for advanced AI chips. The company keeps around 45% of every dollar earned as net profit, which is an exceptionally high margin for any business.
Why do investors care?
The core growth story is simple: AI requires enormous amounts of advanced chips, and TSMC has a near-monopoly on making the most advanced ones. Competitors like Samsung and Intel are years behind in manufacturing capability. For this story to play out, AI infrastructure spending needs to stay strong, TSMC's technology lead must hold, and geopolitical tensions around Taiwan must remain manageable. If all three conditions hold, TSMC's earnings could continue growing at double-digit rates for years.
