What Are Integrated Circuits?

The integrated circuit (or IC) is an essential component of modern electronic equipment and offers many advantages over the separate components used previously.integrated circuits These include lower cost, smaller size, improved reliability, higher processing speed and increased power efficiency.

Integrated circuits are found in almost all modern electronic devices, including computers, mobile phones, microwave ovens, washing machines and televisions.integrated circuits They are classified as either digital, linear or mixed-signal, depending on their intended function.

In 1947, William Shockley and his team at American Telephone and Telegraph Company's Bell Laboratories discovered that electrons would form a barrier or "transfer gate" on the surface of certain crystals when stimulated by electrical signals.integrated circuits They then figured out how to control the flow of electrons through these crystals, performing electrical operations like signal amplification that were previously performed by vacuum tubes. This device, called a transistor, led to the development of integrated circuits.

Before the invention of the IC, individual components were assembled on small ceramic substrates or "chips" with soldered wire connections to connect them. These devices were often very complex and required large spaces to house them. But in the mid Fifties, Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor Corporation independently thought up the idea of reducing circuit size even further by placing very thin paths of metal directly on the same piece of semiconductor material that their devices were made from. These circuits were known as "integrated circuits" or ICs, and they enabled the revolutionary technology of the Information Age to become feasible.

Manufacturing ICs involves'salami slicing' a thin disk of silicon called a wafer into several identical pieces. Then each piece of silicon is doped in different ways to create the desired IC components. Thousands, millions or billions of these are then placed on a single semiconductor chip (known as a die). ICs can be designed as digital devices such as logic gates and microprocessors, or analog devices like audio and instrumentation amplifiers. ICs can also be designed as true systems-on-a-chip (SoC or SOC) that combine both digital and analog functionality.

In addition to the obvious benefits of size and cost, ICs are much more reliable than previous discrete components because there are fewer soldered joints. This makes them easier to repair and maintain. They are also more energy efficient than previous technology because they use a fraction of the power that traditional electronics consume.

Because of their vast utility, ICs are now used in just about everything in the world. For example, airplane autopilots receive input from navigation systems and pilot planning that define a path through the air, a kind of aerial highway. The autopilots then send an error signal back to the ground control system based on this path and the aircraft's actual location. All of this is made possible by a series of very sophisticated ICs, from GPS chips to the autopilots themselves. The entire system owes its life to the IC. Without them, it would be impossible to enjoy the conveniences of our modern world.
