The Complex Process of Making Microchips: How the Brains of Our Electronic World Are Created

TLDRMaking microchips involves a complex process that starts with silicon-rich sand. Silicon, being a semiconductor, allows for the control of electrical signals. The sand is combined with carbon to produce ultrapure silicon. A seed crystal is used to grow a large cylindrical ingot of pure silicon, which is then sliced into wafers. The production process involves deposition, lithography, and doping, creating a three-dimensional microchip. Conducting pathways and layers of metal are added to the chip, and each chip is tested before being separated. The sheer power of microchip technology allows for more powerful devices
