Semiconductors Powering the Digital Economy

Passage

The semiconductor industry occupies a foundational position in the global economy that is broadly disproportionate to its relatively modest direct contribution to employment figures, functioning as the essential substrate upon which virtually all contemporary digital infrastructure depends. The invention of the transistor at Bell Laboratories in 1947 and the subsequent development of the integrated circuit initiated a trajectory of miniaturisation described by Gordon Moore's observation that transistor density on a chip doubles approximately every two years, a heuristic that has guided industry investment and product planning for over five decades. This sustained exponential improvement has made possible the transition from room-sized mainframe computers to smartphones containing processors with billions of transistors etched at nanometre scales. The geopolitical dimensions of semiconductor production have grown increasingly prominent, as the extraordinary capital intensity of advanced fabrication—with leading-edge facilities costing upward of twenty billion dollars—has concentrated cutting-edge manufacturing in a small number of firms concentrated in Taiwan, South Korea, and the Netherlands. Supply chain disruptions during the COVID-19 pandemic exposed the vulnerability of automotive, consumer electronics, and defence industries to semiconductor shortages, prompting governments in the United States, European Union, and China to commit substantial public subsidies toward domestic fabrication capacity in pursuit of strategic self-sufficiency.
