…components, such as transistors, resistors, and capacitors, and their interconnections. These components are fabricated onto a thin, flat piece ("chip") of semiconductor material, most commonly silicon. Integrated circuits are integral to a wide variety of electronic devices (including computers, smartphones, and…
Silicon crystals are the most common semiconducting materials used in microelectronics and photovoltaics.
