The emergence of the integrated circuit is of epoch-making significance: its birth and development have promoted the progress of copper core technology and computers, and brought historic changes in various fields of scientific research and the structure of industrial society. Integrated circuits invented by superior science and technology have enabled researchers to have more advanced tools, which in turn have led to many more advanced technologies. These advanced technologies have further contributed to the emergence of higher performance, cheaper integrated circuits. For electronic devices, the smaller the volume, the higher the integration; the shorter the response time, the faster the calculation and processing speed; the higher the transmission frequency, the greater the amount of information transmitted. The semiconductor industry and semiconductor technology are called the foundation of modern industry, and have also developed into a relatively independent high-tech industry.
