Electronic components has experienced in vacuum tubes, as a representative of the classic electronic components, semiconductor division in time devices including low frequency low speed integrated circuit), as a representative of the miniaturization of electronic components, and the present era with high frequency and high speed processing integrated circuit, as a representative of the microelectronics components era.

   Now the microelectronics components of the formulation of times there are different views, some of the microelectronics as integrated circuit special pronoun, I think electronic circuit is a whole, microelectronics components formulation is early some noun, microelectronics microelectronics) and microelectronics engineering (microelectronicengineering) definition, they call them is a new electronic engineering branch, is the study of the electronic components and integration, namely the miniaturization of research miniature electronic components and circuits technology and science. The party's 13 big report mentioned in the microelectronics technology that is refers to the research, manufacturing and applied micro small electronic components, components and circuits of the technology. 1989 years of the mechanical and electronic industry in the medium and long term program for the development of science and technology and puts forward the development of the new type used in microelectronics assembly components. 1992 "electronic product classification and code", will chip components and flat shape microelectronics components for the microelectronics components, flat to form microelectronics components including head, transformers, connectors, switch, electric meter, relays, microwave components and rf connectors, battery, motor, electronic devices, etc all kinds of flat form parts. So microelectronics components including integrated circuits, hybrid integrated circuit, chip, flat type element and mechanical and electronic components, chip semiconductor division devices, etc. With integrated circuit of integration and complexity substantially improve, the line width thin copper wires and the technology, such as the base frequency and processing speed also greatly raised, in electronic circuit in the surrounding other components must have corresponding processing speed, the rate can be a whole and complete assumes the function-digital multimedia electronic equipment, the high speed, high capacity processing and transmission requirements, so, microelectronics components is the inevitable outcome of the information age and the foundation
