Smaller than a fingernail, Microchips are integrated circuits providing computer circuitry that is one of the most important inventions of the human race.
A microchip is basically an interconnected circuitry of transistors and resistors etched on semiconducting material like germanium or silicon. The Microprocessor of a computer, and the computer memory, both contain microchip circuits. Most modern gadgets contain this piece of technology.
Built on multiple layers, microchip makers use a process called photolithography using chemicals and light. It is generally covered with a thin layer of aluminium.
Apart from computers and laptops, Smartphones are the most common electronic devices carrying a whole lot of chips. Television sets, GPS devices, ID cards and Air Force missiles use this technology.
