Integrated circuits

• Integrated circuit (IC) is a miniature electronic device, consisting of a large number of electronic elements that are structurally and electrically connected to each other. Typically, integrated circuits designed to perform specific functions.

• In fact, the chip combines some electronic circuit where all the elements and an electric connection between them is designed to be placed on a single chip. Since the size of the individual components are very small , on a single chip with the development of modern technology, you can put more than a million electronic components.

• The integrated circuit has several synonyms: chip, microchip, chip. Despite some of the feature definitions of these terms and the difference between them, commonly they are used to refer to integrated circuits.

• In modern electronic devices of a wide variety of applications, ranging from appliances to complex medical and scientific appliances, it is difficult to find the device that was not used integrated circuits. Sometimes one chip performs almost all the functions in the electronic device.

• Integrated circuits are divided into groups according to several criteria. According to the degree of integration, the number of elements placed on the chip. The type of the processed signal: digital, analog and analog-to-digital. According to the technology of their manufacture and materials used – solid state, film, etc.

• In order to protect against external influences the integrated circuit are produced in protective enclosures. The number of elements of the integrated circuit are distinguished: the 1st degree of integration (10 items) the 2nd degree of integration (10 to 100), etc. the size of the individual IC components are very small (about 0.5-10 µm) and often commensurate with the size of the particles (1-100 µm). Poet production of integrated circuits are carried out in persons a clean environment.

• To date, the level of development of technologies in the production of integrated circuits is at a very high level. Increase the degree of integration, improvement of parameters of integrated circuits is not hampered by technological limitations, and the processes occurring at the molecular level, used for the production of materials (typically semiconductors). Therefore, manufacturers and developers of microchips are conducted in the search for new materials that could replace the semiconductors .

Conclusion

• An electronic circuit located on the disc of semiconductor material, usually silicon. Typical integrated circuits have an area of 1.5 sq. mm with a thickness of 0.2 mm.
• All components of transistors, diodes, resistors and resistance, as well as the connecting conductors are placed on the plate in the production process.
