But a skeleton has no soul. To give the chip "life," Silas moved to . He watched the monitors as machines bombarded the silicon with specific atoms, turning bits of the wafer into conductors or insulators. This created the transistors—the tiny switches that would soon be snapping on and off billions of times a second.

The process was a high-stakes dance called . First, a light-sensitive liquid—the photoresist—was spun onto the wafer, coating it in a perfect, glassy film. Then came the stencil, or "mask." It held the blueprint of a labyrinth so complex that if you enlarged it, it would look like a map of every street in the world overlapping ten times.
