The main components of an integrated circuit (IC) typically include transistors, resistors, capacitors, and interconnects. These components are miniaturized and combined onto a single semiconductor substrate, allowing for complex electronic functions in a compact form. Transistors serve as switches or amplifiers, while resistors and capacitors manage voltage and current flow. Integrated circuits are essential in modern electronics, powering devices such as computers, smartphones, and appliances, facilitating advancements in technology, and contributing to the miniaturization of electronic devices.
