It is a semiconductor manufacturing process such as oxidation, light engraving, diffusion, extension, steamed aluminum, etc., and integrates all semiconductors, resistors, capacitors and other components required for circuits with certain functions, and the connection wires between them are integrated in a small piece of silicon. On the film, the electronic device welded in a tube was welded.
Its encapsulation shell has a variety of forms such as round shell, flat or dual -column direct insertion. Integrated circuit technology includes chip manufacturing technology and design technology, which is mainly reflected in the ability of processing equipment, processing technology, packaging testing, mass production and design innovation.
The integrated circuit can be divided into three categories: simulation integrated circuits, digital integrated circuits, and digital/modular integrated integrated circuits according to their functions and structures.
The simulation integrated circuit is also called a linear circuit, which is used to generate, enlarge and process various analog signals (refer to signals that change with time with time.
For example, the audio signal of the semiconductor radio, the tape signal of the player, etc.), the input signal and the output signal are proportional. The digital integration circuit is used to generate, enlarge and process various digital signals (refer to signals that discrete the value at time and amplitude. And video signal).
The application of hybrid integrated circuits is mainly analog circuits and microwave circuits, and it is also used in special circuits with high voltage and large currents. For example, data conversion circuits, numbers-model and mormonal-digital converters, etc. in portable radio stations, airborne radio stations, electronic computers and microprocessors. Applications in the field of microwave are particularly prominent.
Three set circuits
Integrated circuits can be divided into television integrated circuits, integrated circuits, video disc, integrated circuits, computer (microcomputer) for integrated circuits, computer (microcomputers), integrated circuits, communications, and cameras for integrated circuits, computer (microcomputer) for video disc Circuit, remote control integrated circuits, language integrated circuits, alarms for integrated circuits and various dedicated integrated circuits.

5. Computer integrated circuits, including central control units (CPUs), memory, external memory, I/O control circuits, etc.
The integrated circuit has the advantages of small volume, light weight, small lines and welding points, long life, high reliability, and good performance. At the same time, the cost is low, which is convenient for large -scale production. It is not only widely used in industrial and civil electronic equipment such as collectors, televisions, and computers, but also widely used in military, communication, and remote control. The integrated circuit is used to assemble electronic equipment. The assembly density can be increased by dozens to thousands of times compared with the transistor, and the stable working time of the equipment can also be greatly improved.
