Here is a list of 28 Integrated Circuits categories. It encompasses a wide range including ic linear regulators, microwave monolithic integrated circuits (mmic), fpgas, load switch ics, etc. You can search for an overview, principle, and usage of each category, as well as find manufacturers and distributors.
Integrated Circuits are electronic components that are loaded with a concentration of circuits.
Often abbreviated as IC, it is an electronic circuit in which a number of electronic elements with various functions are assembled on a single semiconductor substrate and connected to each other by internal wiring to perform a specific function.
A circuit consists of multiple circuit elements and the wiring that connects them. These circuit elements are mainly resistors, capacitors, and transistors. By combining all of these elements and wiring into a single substrate (chip), the level of integration is increased.
ICs are used in all kinds of electrical products in the world, and the miniaturization of ICs has enabled us to use compact and convenient products such as smartphones.
Among ICs, large scale ICs with 100,000 to 10 million elements are called LSI (Large Scale Integrated).
Before the development of Integrated Circuits, each electronic element (resistor, diode, capacitor, transistor, etc.) had to be mounted individually on a printed circuit board and connected by external wiring.
In contrast, in popular semiconductor circuits, capacitors and resistors (passive elements) and diodes and transistors (active elements) are placed on a single-crystal silicon semiconductor substrate and connected to each other by internal wiring. Compared to the age of the ore radio, the size has been miniaturized to less than 1/30,000th of its original size and less than 1/1 billionth of its area.
Integrated Circuits are made of semiconductors. A semiconductor is a substance that is between a conductor and an insulator and has the property of conducting a small amount of electricity. There are various types of semiconductors, but in general ICs are made of silicon.
By combining pure silicon crystals with a mixture of impurity atoms, transistors can be made in which the flow of electricity (electrons) can be controlled. Large-scale combinations of these transistors can be used to assemble logic circuits that perform calculations and processing. Resistors, capacitors, and wiring can also be manufactured by processing silicon in the same way.
In the manufacturing process, hundreds to thousands of Integrated Circuits are baked at a time on silicon crystal disks called wafers using optical equipment in a clean facility called a clean room. Then, they are separated into individual pieces, wires are attached to connect them to the outside world, and packaging is completed.
