An integrated circuit or monolithic integrated circuit also referred to as an IC , a chip , or a microchip is a set of electronic circuits on one small flat piece or "chip" of semiconductor material that is normally silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to integrated circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors.

Integrated circuits ICs are a keystone of modern electronics. They are the heart and brains of most circuits. They are the ubiquitous little black "chips" you find on just about every circuit board. Unless you're some kind of crazy, analog electronics wizard, you're likely to have at least one IC in every electronics project you build, so it's important to understand them, inside and out.
Integrated circuits are the little black "chips", found all over embedded electronics. An IC is a collection of electronic components -- resistors , transistors , capacitors , etc.
They come in all sorts of flavors: single-circuit logic gates, op amps, timers, voltage regulators, motor controllers, microcontrollers, microprocessors, FPGAs Integrated circuits are one of the more fundamental concepts of electronics. They do build on some previous knowledge, though, so if you aren't familiar with these topics, consider reading their tutorials first When we think integrated circuits, little black chips are what come to mind.
But what's inside that black box? The guts of an integrated circuit, visible after removing the top. The real "meat" to an IC is a complex layering of semiconductor wafers, copper, and other materials, which interconnect to form transistors, resistors or other components in a circuit.
The cut and formed combination of these wafers is called a die. While the IC itself is tiny, the wafers of semiconductor and layers of copper it consists of are incredibly thin. The connections between the layers are very intricate. Here's a zoomed in section of the die above:. An IC die is the circuit in its smallest possible form, too small to solder or connect to. To make our job of connecting to the IC easier, we package the die. The IC package turns the delicate, tiny die, into the black chip we're all familiar with.
The package is what encapsulates the integrated circuit die and splays it out into a device we can more easily connect to. Each outer connection on the die is connected via a tiny piece of gold wire to a pad or pin on the package. Pins are the silver, extruding terminals on an IC, which go on to connect to other parts of a circuit.
These are of utmost importance to us, because they're what will go on to connect to the rest of the components and wires in a circuit. All ICs are polarized , and every pin is unique in terms of both location and function. This means the package has to have some way to convey which pin is which.
Most ICs will use either a notch or a dot to indicate which pin is the first pin. Sometimes both, sometimes one or the other. Once you know where the first pin is, the remaining pin numbers increase sequentially as you move counter-clockwise around the chip. One of the main distinguishing package type characteristics is the way they mount to a circuit board. Through-hole packages are generally bigger, and much easier to work with. They're designed to be stuck through one side of a board and soldered to the other side.
Surface-mount packages range in size from small to minuscule. They are all designed to sit on one side of a circuit board and be soldered to the surface.
The pins of a SMD package either extrude out the side, perpendicular to the chip, or are sometimes arranged in a matrix on the bottom of the chip. ICs in this form factor are not very "hand-assembly-friendly. DIP, short for dual in-line package, is the most common through-hole IC package you'll encounter. These little chips have two parallel rows of pins extending perpendicularly out of a rectangular, black, plastic housing. The overall dimensions of a DIP package depend on its pin count, which may be anywhere from four to The area between each row of pins is perfectly spaced to allow DIP ICs to straddle the center area of a breadboard.
This provides each of the pins its own row in the board, and it makes sure they don't short to each other. They're inserted into one side of the board and soldered into place on the other side. Sometimes, instead of soldering directly to the IC, it's a good idea to socket the chip.
Using sockets allows for a DIP IC to be removed and swapped out, if it happens to "let its blue smoke out. There is a huge variety of surface-mount package types these days. In order to work with surface-mount packaged ICs, you usually need a custom printed circuit board PCB made for them, which has a matching pattern of copper on which they're soldered.
Here are a few of the more common SMD package types out there, ranging in hand-solderability from "doable" to "doable, but only with special tools" to "doable only with very special, usually automated tools".
It's what you'd get if you bent all the pins on a DIP outward, and shrunk it down to size. With a steady hand, and a close eye, these packages are among the easiest SMD parts to hand solder. On SOIC packages, each pin is usually spaced by about 0. Mounted on a board in the middle quarter added for size-comparison.
Splaying IC pins out in all four directions gets you something that might look like a quad flat package QFP. Sometimes they wrap around, and are exposed on both the side and bottom, other packages only expose the pad on the bottom of the chip.
These are amazingly intricate little packages where little balls of solder are arranged in a 2-D grid on the bottom of the IC. Sometimes the solder balls are attached directly to the die! BGA packages are usually reserved for advanced microprocessors, like those on the pcDuino or Raspberry Pi. Usually, to put these packages onto a PCB requires an automated procedure involving pick-and-place machines and reflow ovens.
Integrated circuits are prevalent in so many forms across electronics, it's hard to cover everything. Here are a few of the more common ICs you might encounter in educational electronics. Logic gates, the building blocks of much more ICs themselves, can be packaged into their own integrated circuit. Logic gates can be connected inside an IC to create timers, counters, latches, shift registers, and other basic logic circuitry. Microcontrollers, microprocessors, and FPGAs, all packing thousands, millions, even billions of transistors into a tiny chip, are all integrated circuits.
These components exist in a wide range in functionality, complexity, and size; from an 8-bit microcontroller like the ATmega in an Arduino , to a complex bit, multi-core microprocessor organizing activity in your computer. These components are usually the largest IC in a circuit.
As these components grow in complexity, the package gets equally complex. Modern digital sensors, like temperature sensors, accelerometers , and gyroscopes all come packed into an integrated circuit. These ICs are usually smaller than the microcontrollers, or other ICs on a circuit board, with pin counts in the three to twenty range. Integrated circuits are present in just about every circuit out there.

Integrated circuit IC , also called microelectronic circuit , microchip , or chip , an assembly of electronic components, fabricated as a single unit, in which miniaturized active devices e. The individual circuit components are generally microscopic in size. Integrated circuits have their origin in the invention of the transistor in by William B. Brattain found that, under the right circumstances, electrons would form a barrier at the surface of certain crystals , and they learned to control the flow of electricity through the crystal by manipulating this barrier. Controlling electron flow through a crystal allowed the team to create a device that could perform certain electrical operations, such as signal amplification, that were previously done by vacuum tubes. They named this device a transistor, from a combination of the words transfer and resistor. The study of methods of creating electronic devices using solid materials became known as solid-state electronics.

The influence of this will be similar to the transition of discrete transistors to integrated circuits. Sensors and display units as liquid crystals will gain importance and need to be interconnected in an economic way. Competing with printed circuit boards are hybrid circuits, but these have not yet found general application due to the high innovation rate of integrated circuits. However, special applications as high frequency circuits are cost effective.
