TSMC’s \$100 Billion Bet: Bringing AI Chip Technology to the U.S.

In a landmark move that underscores the escalating tech rivalry between the U.S. and China, Taiwan Semiconductor Manufacturing Company (TSMC) has announced a $100 billion investment in American soil — the largest foreign investment in U.S. history. Central to this investment is “advanced packaging,” a rapidly growing area of chip technology that’s become essential in the race to dominate artificial intelligence (AI).

Traditionally, packaging simply meant encasing a chip in a protective shell. But today’s advanced packaging — pioneered by TSMC’s CoWoS (Chips-on-Wafer-on-Substrate) — brings multiple chips, like GPUs and memory units, closer together. This proximity allows them to communicate faster, use less power, and ultimately perform more efficiently — all critical features for running AI applications.

Think of it like putting different departments in an office building on the same floor rather than across town — communication becomes seamless and faster. As AI needs surge globally, this once-overlooked step in chipmaking has become a game-changer.

TSMC’s expansion includes two new advanced packaging facilities in Arizona, giving the U.S. its first comprehensive chip manufacturing chain — from production to packaging — on home turf. This "one-stop shop" strengthens America’s AI competitiveness and diversifies production away from Taiwan, which currently handles almost all global advanced packaging.

The move not only benefits tech giants like Nvidia, AMD, Apple, and Qualcomm — TSMC’s key clients — but also mitigates geopolitical risks tied to Taiwan’s tense position in U.S.-China relations.

CoWoS wasn't always a blockbuster. When TSMC’s Chiang Shang-yi introduced it in 2009, high costs and limited demand made it a hard sell. Fast forward to today, and nearly every major AI chip — especially Nvidia’s — depends on it.

With demand quadrupling in just two years, even competitors like Samsung, Intel, and OSAT firms such as ASE Group and Amkor are racing to scale up advanced packaging capabilities.

In a world increasingly driven by AI, the future of computing may not only hinge on smarter algorithms — but also on how close we can get our chips to talk to each other. And now, thanks to TSMC’s latest move, some of that future is being built in Arizona.
