A semiconductor IC is a small electronic circuit comprising active and passive electronic components, like transistors, diodes, resistors, and capacitors, integrated on a small piece of semiconductor material, typically silicon. IC is used in a wide range of electronic devices, including computers, smartphones, audio and video equipment, and automotive systems. A semiconductor IC is essential to the functioning of modern electronics and has revolutionized the design and manufacture of electronic devices by enabling complex circuits to be created on a single chip.
