Integrated Circuits (ICs) have revolutionized the landscape of modern technology, serving as the backbone of virtually every electronic device we use today. An integrated circuit is a set of electronic circuits on a small flat piece (or "chip") of semiconductor material, typically silicon. The evolution of ICs has been remarkable, beginning in the late 1950s with the invention of the first transistor and leading to the complex microprocessors and system-on-chip (SoC) designs we see today. The importance of ICs cannot be overstated; they enable the functionality of everything from smartphones to advanced medical devices, making them a critical component in our daily lives.
Integrated circuits can be categorized into three main types:
