As the cornerstone of modern electronic technology, the semiconductor industry has a full industrial chain covering a wide range of fields from upstream materials and equipment to midstream design and manufacturing, and then to downstream applications. This industrial chain is not only highly technology-intensive, but also has a huge market size, which has an important impact on the global economy. In the upstream link, the semiconductor industry chain mainly includes semiconductor materials, production equipment and EDA (electronic design automation) software. Semiconductor materials are the foundation of the industrial chain, including silicon wafers, photoresists, electronic gases, etc. The quality and performance of these materials directly affect the subsequent manufacturing links. In terms of production equipment, high-tech threshold equipment such as lithography machines, etching machines, and thin film deposition equipment are the core of wafer manufacturing. EDA software is a key tool for chip design. Through computer-aided design software, engineers can efficiently complete circuit design, simulation and verification. The midstream link is the core of the semiconductor industry chain, including three main steps: integrated circuit design, wafer manufacturing and packaging testing. Integrated circuit design is the starting point of the industrial chain. The design team uses EDA software to design circuits based on market demand and product specifications, and continuously optimizes to improve performance and reduce costs. Wafer manufacturing is to transfer the designed circuit diagram to the silicon wafer, and form the basic structure of the chip through complex process steps such as lithography, etching, and thin film deposition. Packaging and testing is to package the manufactured chips and perform performance and reliability tests to ensure that the chips meet the specifications. The downstream link is the application field of semiconductor products, including PC, medical, electronics, communications, Internet of Things, information security, automobiles, new energy, industry and other fields. With the continuous development of emerging technologies, especially the rapid rise of artificial intelligence, 5G, Internet of Things and other fields, the demand for high-performance semiconductors continues to grow. For example, in the field of data centers, high-performance semiconductor products such as AI chips and storage chips have become key components; in the field of automotive electronics, with the acceleration of automotive electronics, the demand for semiconductor products is also increasing. Looking to the future, the entire semiconductor industry chain will continue to be driven by both technological innovation and market demand. With the extreme challenge of Moore's Law, new technologies such as three-dimensional integration and heterogeneous integration will become breakthrough directions, driving the industry chain to a higher level. At the same time, competition in the global semiconductor market will become more intense, and countries and regions will increase investment and strengthen cooperation to jointly respond to challenges such as supply chain security and technological blockades. As a rising star, Under the dual influence of policy guidance and market demand, China's semiconductor industry will accelerate its catch-up with the international advanced level and contribute China's strength to the prosperity and development of the global semiconductor industry.
