Microelectronic technology is the technical field of the development, production and application of micro electronic components and circuits to realize the functions of electronic systems. In this field, the main is integrated circuit technology. Therefore, microelectronics technology is an emerging technology developed with the development of integrated circuit technology, especially large-scale integrated circuit technology. Compared with traditional electronic technology, microelectronic technology can not only miniaturize electronic equipment and systems, but also cause great changes in the design, process and packaging of electronic equipment and systems. The starting point of integrated circuit design is no longer a single component, but the whole system or equipment. Traditional components such as transistors, resistors, wires and so on are connected to each other in an integral form in the silicon substrate. Microelectronics is a branch of electronics that studies miniaturized circuits, circuits and systems composed of solid (mainly semiconductor) materials. As a branch of electronics, it mainly studies the motion law and application of electrons or particles in solid materials, and uses it to realize the science of signal processing function, for the purpose of circuit system and integration.

Microelectronics is also an important basic discipline in the field of information. In this field, microelectronics is the science to study and realize information acquisition, transmission, storage, processing and output. It is the science to study information acquisition and constitutes the cornerstone of information science. Its development level directly affects the development of the whole information technology. The development level and industrial scale of microelectronics science and technology is an important symbol of a country's economic strength. Microelectronics is a comprehensive frontier discipline, including semiconductor device physics, integrated circuit technology, integrated circuit and system design and testing; It involves many fields, such as solid-state physics, quantum mechanics, thermodynamics and statistical physics, material science, electronic circuits, signal processing, computer-aided design, testing and processing, graph theory, chemistry and so on. Microelectronics is a rapidly developing discipline. High integration, low power consumption, high performance and high reliability are the development direction of microelectronics. The development direction of information technology is multimedia (Intelligence), networking and individualization. The system is required to acquire and store a large amount of multimedia information, process and transmit these information reliably at a very high speed, and display or control the useful information in time. All these can only be realized by relying on the support of microelectronic technology. Ultra high capacity, ultra-small, ultra-high speed, ultra-high frequency and ultra-low power consumption are the endless goal of information technology and the driving force for the rapid development of microelectronics technology. Microelectronics has strong permeability, and the combination of other disciplines has produced a series of new interdisciplinary disciplines. MEMS and biochip are representatives of this field. They are new technologies with broad application prospects developed in recent years.
