What is the name of a device that combines several semiconductors and other components into one package?

An integrated circuit (IC), commonly known as a microchip, is a small electronic package that contains a highly miniaturized circuit. These chips integrate multiple semiconductors, such as transistors, along with passive components like resistors and capacitors, onto a single piece of semiconductor material. This massive integration allows complex systems, such as microprocessors or complete radio receivers, to be manufactured in very small spaces. In contrast, a transducer converts energy from one form to another (like a microphone), a multi-pole relay is an electromechanical switch, and a transformer relies on magnetic fields to change AC voltage levels.
