The semiconductor industry is mainly engaged in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting applications, high-power power conversion and other fields.
Semiconductor industry belongs to the electronic information industry, belongs to the hardware industry, and is an industry developed based on semiconductors.
Whether from the perspective of science and technology or economic development, the importance of semiconductors is very huge. The core unit of most electronic products, such as computers or digital tape recorders, is closely related to semiconductors.
Common semiconductor materials silicon, germanium and gallium arsenide, of which silicon is the most influential one in various semiconductor material applications.
Semiconductor equipment in a broad sense includes three parts: semiconductor material manufacturing equipment, semiconductor processing equipment and semiconductor packaging and testing equipment, which respectively serve the three major links of raw material manufacturing, wafer processing and packaging and testing in the semiconductor manufacturing industry chain.
Upstream - software and hardware materials and equipment
The upstream is the underlying foundation of the overall semiconductor industry, providing support for the semiconductor industry, and is composed of semiconductor materials and semiconductor equipment. The materials involved include fine chemical plants such as copper, sulfuric acid, ten kinds of non-ferrous metals, and equipment suppliers such as lithography machines and testing equipment. In terms of raw materials, copper, sulfuric acid and ten kinds of non-ferrous metals are important raw materials for the manufacture of semiconductor material products, and the supply shows a relatively stable trend, and the factors affected by the price are relatively small, so the upstream fine chemical plant does not have high bargaining power in the entire industrial chain.
Midstream – IC design and production
For the semiconductor manufacturing industry chain, including IC design, manufacturing, packaging and testing three links, its products mainly include integrated circuits, discrete devices, optoelectronic devices and sensors, of which integrated circuits are the largest.
Downstream - IC industry and application
It is the specific application field of semiconductors, involving consumer electronics, mobile communications, new energy, artificial intelligence, aerospace and other fields, and downstream application industries such as PC tablets and industrial healthcare
