The emergence and rapid development of the electronic components industry in the 20th century has brought about earth-shaking changes to the entire world and people\'s working and living habits. The development history of electronic components is actually the development history of the electronics industry.

In 1906, American De Forest invented the vacuum triode to amplify the sound current of telephones. Since then, people have strongly looked forward to the birth of a solid-state device that can be used as amplifiers and electronic switches that are lightweight, cheap, and long-lasting. In 1947, the birth of the point-contact germanium transistor opened a new page in the history of the development of electronic devices. However, this point-contact transistor has a fatal weakness in its structure that the contact point is unstable. When point contact transistors were successfully developed, the theory of junction transistors had already been proposed. However, it was not until people were able to prepare ultra-high-purity single crystals and arbitrarily control the conductivity type of the crystal that junction transistor materials truly emerged. In 1950, the earliest germanium alloy transistor with practical value was born. In 1954, the junction silicon transistor was born. Since then, people have proposed the idea of field effect transistors. With the emergence and development of material technologies such as defect-free crystallization and defect control, crystal exogenous growth technology and diffusion doping technology, pressure-resistant oxide film preparation technology, corrosion and photolithography technology, various electronic devices with excellent performance have emerged one after another. , electronic components gradually moved from the vacuum tube era to the transistor era and the large-scale and ultra-large-scale integrated circuit era. Gradually formed the semiconductor industry as a representative of high-tech industry.

Due to the needs of social development, electronic devices have become more and more complex, which requires electronic devices to have the characteristics of reliability, fast speed, low power consumption, light weight, miniaturization, and low cost. Since the idea of integrated circuits was proposed in the 1950s, due to advances in comprehensive technologies such as material technology, device technology, and circuit design, the first generation of integrated circuits was successfully developed in the 1960s. in the history of semiconductor development. The emergence of integrated circuits is of epoch-making significance: its birth and development promoted the advancement of copper core technology and computers, bringing historic changes to various fields of scientific research and the structure of industrial society. The integrated circuit invented with superior science and technology gave researchers more advanced tools, which in turn produced many more advanced technologies. These advanced technologies will further promote the emergence of higher-performance, cheaper integrated circuits. For electronic devices, the smaller the size, the higher the integration level; 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 known as the foundation of modern industry, and have also developed into a relatively independent high-tech industry.
