Abstract
The complex circuitry of a microchip appears flat and one dimensional but, in reality, it can have as many as twenty layers. The starting point for what ends up looking like a miniature electronic city is pure silicon, grown from seed crystals. As a semiconductor, its degree of conductivity can be modified and controlled, making it ideally suited for an electronic on-off switch. The silicon is sliced into wafers, polished and cleaned prior to the creation of the microchip. The design pattern for each layer of the chip--some large enough to cover an entire wall--is photographically reduced using high precision optics. Photolithography, etching, doping and other related processes are repeated until all the layers of the chip circuitry are completely built.
