Circuitry of microchip. Coloured scanning electron micrograph (SEM) of the tracks (narrow strips) that make up the circuitry of a microchip. The tracks are made by various deposition and etching techniques to form what is termed an integrated circuit. Microchips allow compact and reliable electronic devices to be made. This is part of the integrated circuit of an Intel 486 central processing unit (CPU). CPUs are data- processing devices that are the central component of a computer. Magnification: x905 at 6x7cm size.
