Why Taiwan’s semiconductor industry matters to Milwaukee’s manufacturers and tech sectors

Taiwan produces a disproportionate share of the world’s most advanced semiconductors. That fact is not a statistic of the technology industry. It is a supply chain reality that reaches into automotive plants, medical device manufacturers, defense contractors, and the research institutions across the globe and into the American Midwest.

The distance between a fabrication facility in Taiwan and a manufacturer in the Milwaukee region is measurable in the components that move between them, invisibly and continuously, until they do not. A semiconductor is a component whose electrical conductivity can be precisely controlled, making it the functional foundation of every electronic device built in the modern era.

Microprocessors, memory chips, sensors, and power management components are semiconductors. They all require fabrication, the physical process of etching microscopic circuits onto silicon wafers in a controlled environment. The design of those circuits happens in many places. The advanced fabrication, which is the manufacturing of chips at the smallest, most capable nodes, happens in very few locations.

Taiwan Semiconductor Manufacturing Company, known as TSMC, is the world’s largest dedicated semiconductor foundry and the dominant producer of the most advanced chips currently manufactured at commercial scale. TSMC’s market position in advanced node fabrication is not a recent development. It is the product of decades of deliberate industrial policy by Taiwan’s government, sustained capital investment at a scale that requires returns over decades rather than quarters, and the accumulation of technical expertise that cannot be replicated quickly, regardless of how much money is committed to the attempt.

The United States, Japan, and the European Union have all announced significant semiconductor manufacturing investment programs in recent years. Those programs will take years to produce advanced fabrication capacity at a meaningful scale, and the gap between their current output and TSMC’s remains substantial. TSMC currently produces the majority of the world’s most advanced chips, those manufactured at the smallest process nodes that current technology supports.

The physical geography of that production is concentrated in a specific location. Hsinchu Science Park, established on Taiwan’s northwestern coast in 1980, developed over the following four decades into the world’s most significant semiconductor manufacturing cluster. TSMC’s primary fabrication facilities are located there, surrounded by a dense ecosystem of suppliers, equipment manufacturers, materials producers, and research institutions that feed technical talent and specialized components into the production process.

The park houses hundreds of companies whose operations are integrated into the semiconductor supply chain at different levels of specialization. That concentration is not an accident of geography. It is the outcome of a deliberate industrial development strategy that organized public investment, university research, and private capital around a specific technological objective and sustained that organization long enough for the cluster to become self-reinforcing. The expertise, infrastructure, and supplier relationships concentrated in Hsinchu took decades to build and cannot be relocated or replicated on a short timeline.

The industries whose production depends on advanced semiconductor availability span the full range of modern manufacturing. Automotive production requires semiconductor components for engine management, safety systems, navigation, and the increasingly complex electronic architecture of modern vehicles.

The semiconductor shortages of 2021 and 2022 demonstrated the dependency in terms that every major automaker understood directly. Production lines stopped because chips were unavailable, not because steel or glass or labor was scarce.

Medical device manufacturing depends on semiconductors for diagnostic equipment, implantable devices, monitoring systems, and the computational infrastructure of modern healthcare. Defense electronics require advanced chips for communications, guidance systems, surveillance, and the processing capacity that modern military operations depend on. Consumer technology, which is the most visible semiconductor application, represents only one segment of a dependency that runs through every sector of the modern industrial economy.

Those sectors are present in the Milwaukee region’s manufacturing base. The industrial economy of Milwaukee includes precision machinery manufacturers, medical device producers, industrial equipment companies, and the research and development infrastructure of the University of Wisconsin-Milwaukee and other regional institutions. The companies operating in those sectors do not manufacture semiconductors. They use them in components sourced through supply chains that run, at some point, through the fabrication capacity concentrated in Taiwan.

The Milwaukee region’s manufacturing base learned the hard lesson about the disruption of chip production alongside every other industrial cluster in the country. Precision machinery manufacturers whose products incorporate electronic controls and sensing systems, medical device companies whose diagnostic and therapeutic equipment depends on semiconductor components, and industrial equipment producers whose automation systems require advanced processing capacity.

The companies operating within and around Hsinchu today include not only TSMC but the hundreds of specialized suppliers, equipment manufacturers, chemical producers, and engineering firms whose operations are integrated into the semiconductor production process at every level. That industrial ecosystem is what makes Taiwan’s semiconductor position durable and the supply chain dependency structural rather than incidental.

Relocating semiconductor fabrication capacity requires moving not only the equipment itself among the most complex and expensive manufacturing equipment in the world, but the entire supporting ecosystem that makes advanced fabrication possible. The efforts currently underway to build semiconductor manufacturing capacity in the United States, Japan, and Europe represent genuine progress toward diversification.

However, they do not represent a near-term resolution of the dependency on Taiwan. The timelines for those facilities to reach full production at advanced nodes extend well beyond any reasonable short-term planning horizon for manufacturers in the Milwaukee region.

The UWM-CYCU engineering partnership places Milwaukee at the intersection of this supply chain in a specific way. Students from Chung Yuan Christian University — a Taiwanese technical university whose graduates have contributed to the semiconductor and electronics industries anchored by Hsinchu Science Park — complete their final two undergraduate years at UWM before entering the American engineering workforce.

The engineers this partnership produces carry technical formation shaped by Taiwan’s semiconductor industrial culture into careers in Milwaukee’s manufacturing and research sectors. That connection does not appear in supply chain analyses or trade statistics. It is present in the professional networks and technical knowledge of individuals whose education spans both sides of the Pacific.

For Milwaukee’s manufacturers and research institutions, that human connection may be the most durable form of supply chain awareness available. Policy shifts, tariff structures, and geopolitical pressure can disrupt the flow of components. But they do not erase the technical fluency of engineers who have worked within both systems.

As the global competition over semiconductor capacity intensifies and the vulnerability of concentrated production becomes a recurring subject of trade and defense policy, the quiet investment in cross-Pacific technical education represents a form of supply chain preparedness that belongs in Milwaukee’s risk assessment.
