ASML vs. TSMC: Which Semiconductor Supply Chain Stock Is the Better AI Play?

Both of these companies person been more-than-solid winners implicit the past 5 years, with nett income for Taiwan Semiconductor (TSMC for short) rising 251% successful that time, and gross expanding by 165%. ASML has been beardown arsenic well, with amended than 90% gains successful some nett income and revenue.

Missed Nvidia successful 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" awesome flashed for a little-known chipmaker called Nvidia. For the archetypal clip successful years, that aforesaid "Total Conviction" awesome is flashing for a institution 1/100th the size of Nvidia. Continue »

Their shares successful the past 5 years person outpaced the tech-heavy Nasdaq Composite by a wide margin.

Both of these AI stocks person been large investments. But arsenic we look forward, which appears to beryllium the amended AI play?

Taiwan Semiconductor Manufacturing

TSMC is the world's largest semiconductor spot manufacturer. The institution is estimated to person 73% of the planetary foundry market, up from 69% successful the 4th fourth of 2024. It fabricated much than 12,600 antithetic products successful 2025, utilizing 305 antithetic process technologies.

Its latest manufacturing exertion is the 2-nanometer process, which offers higher density and vigor efficiency. The institution has been a person successful processing precocious fabrication abilities, with its 3-nm and 5-nm technologies generating much than 60% of its gross successful caller quarters. It brought successful gross for its 2-nm process for the archetypal clip successful the astir caller quarter.

Data source: TSMC.

TSMC besides announced a $100 cardinal enlargement of its mill successful Arizona, which would enactment precocious packaging fabs and its 2-nm processing technology.

Revenue successful the 2nd 4th was $40.2 billion, up 33.7% from a twelvemonth ago, and the company's nett net borderline was 55.6%.

ASML

As important arsenic TSMC is to the semiconductor proviso chain, ASML makes the occupation overmuch easier. The Dutch institution makes machines that TSMC and different foundries request to nutrient minuscule circuits and components etched connected semiconductor chips.

Most spot manufacturing relies connected heavy ultraviolet (DUV) exertion and lenses to absorption tiny airy beams to marque microscopic circuit patterns connected silicon wafers. ASML sells DUV machines, but it besides sells more-advanced utmost ultraviolet (EUV) exertion that uses mirrors alternatively of lenses. That greater precision allows EUV machines to execute tasks that DUV machines cannot.
