TAINAN, Taiwan — The United States and China are wrestling to lead the world in artificial intelligence, 5G wireless and other cutting-edge technologies. But the real wizardry that makes those advancements possible is being performed on a yam-shaped island that sits between them, geographically and politically.
On Taiwan’s southern rim, inside an arena-size facility stretched out among lush greenery and coconut palms, colossal machines are manipulating matter at unimaginably tiny scale. A powerful laser vaporizes droplets of molten tin, causing them to emit ultraviolet light. Mirrors focus the light into a beam, which draws features into a silicon wafer with the precision, as one researcher put it, “equivalent to shooting an arrow from Earth to hit an apple placed on the moon.”
The high-performance computer chips that emerge from this process go into the brains of the latest tech products from both sides of the Pacific. Or at least they
