Three Generations of Semiconductors Research and Bottleneck of Development

Abstract

The new technological revolution triggered by semiconductors is affecting all aspects of production and life. However, the semiconductor industry is difficult to develop and has yet to meet the high demand in many fields. This thesis explores the semiconductor industry in depth from the perspective from material performance to industry chain, exploring the development process of the three generations of semiconductors, applications, and their bottleneck. The research also explores the development of semiconductors from the nature of their materials, technology, market industry and other dimensions. The energy gap of the three generations of semiconductors is increasing, the breakdown voltage increases with it, and the semiconductor operating voltage increases as a result. Third-generation semiconductors have the highest heat conduction, so they can be adapted to more extreme working environments, and have great application prospects. Semiconductors are used in a wide range of applications, which are the cornerstone of smart healthcare, the core technology of smart manufacturing products, and the heart of information and communication. Semiconductor industry is facing difficulties in wafer manufacturing technology and the market structure of the existence of monopoly. It's the national strategic security of high-tech, but building a complete industry chain construction is difficult. Semiconductor development requires multidisciplinary innovation, multi-participation, and multidisciplinary integration. This paper provides a reference for the understanding of semiconductor evolution and new ideas for the macro development of the semiconductor industry.
