  1. A semiconductor is a material that has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. Its resistivity generally falls as its temperature rises; metals behave in the opposite way.

    Semiconductors are materials that can control the flow of electricity more than insulators (nonconductors) but less than conductors. They are used in many electronic devices, including computers and smartphones.

    The history of the understanding of semiconductors begins with experiments on the electrical properties of materials. The properties of the time-temperature coefficient of resistance, rectification, and light-sensitivity were observed starting in the early 19th century.
    A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators.
    Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuits (ICs) such as computer processors, microcontrollers, and memory chips (such as NAND flash and DRAM) that are present in everyday electronic devices.
    What is a semiconductor? An electrical engineer explains how these critical electronic components work and how they are made Thin, round slices of silicon crystals, called wafers, are the starting point for most semiconductor chips.
