Summary:

Integrated circuits (ICs) are miniature electronic circuits that are etched onto a small piece of semiconductor material, typically silicon. These circuits contain transistors, resistors, capacitors, and other electronic components, all integrated onto a single chip. ICs revolutionized the field of electronics by making it possible to pack more functionality into smaller devices, leading to the development of computers, smartphones, and countless other electronic devices we use today.

Overview:

Integrated circuits, also known as microchips or chips, are the building blocks of modern electronics. They are made by fabricating multiple electronic components onto a single piece of semiconductor material, usually silicon. The process involves etching microscopic patterns onto the silicon using various techniques, such as photolithography.
