Semiconductor: the conductivity is between insulator and conductor.
Semiconductors are usually made of silicon. Their conductivity is higher than that of insulators such as glass, but lower than that of pure conductors such as copper or aluminum. The conductivity and other properties can be changed by introducing impurities (called doping) to meet the specific requirements of the electronic components in which they reside. Semiconductors are also called semiconductors or chips. They can be found in thousands of products, such as computers, smart phones, devices, game hardware and medical devices.
From the perspective of materials, semiconductors, as the name implies, refer to materials whose conductivity is between conductors and insulators at room temperature. Integrated circuits can be formed by processing semiconductor materials, and integrated circuits can be packaged and tested to form chips.
