About this listen

We hold a supercomputer in our hands, a seamless piece of glass and metal. But how do we manufacture its brain—a microchip with billions of parts a thousand times thinner than a hair? This episode deconstructs the most precise manufacturing process in human history, revealing how we use stencils, acid, and a mind-bending trick with the physics of light to turn common sand into thinking matter.
