Domestic Substitution in Semiconductors
The term refers to the domestic enterprises in the semiconductor industry chain (including equipment, materials, design, manufacturing, packaging, testing, etc.) gradually replacing foreign semiconductor products and services through technological breakthroughs and capacity enhancements, achieving self-control of the industry chain, reducing dependence on overseas semiconductor industries, and ensuring the safety of domestic technology industries and supply chain stability.
Equipment / Materials
Semiconductor equipment is the core tool for semiconductor manufacturing, packaging, and other processes, such as photolithography machines, etching machines, and thin film deposition equipment; semiconductor materials are the basic raw materials required for semiconductor product production, such as silicon wafers, photoresists, and electronic specialty gases. They are the cornerstone of semiconductor industry development, and the demand for domestic substitution is urgent.
Advanced Packaging
It is a packaging technology that can achieve high-density interconnection between chips, enhancing chip performance and integration. Compared to traditional packaging, it can realize more functions in a smaller space, meeting the performance requirements of high-end chips (such as AI chips and computing power chips), and is a key link in the semiconductor industry chain to enhance chip added value.
CPU (Central Processing Unit)
The CPU is the core of the computer system’s computation and control, responsible for executing instructions and processing data, widely used in general computing, servers, and terminal devices. It is a core basic component of the information industry, and breakthroughs in domestic CPUs are of great significance for semiconductor domestic substitution.
GPU (Graphics Processing Unit)
Initially used for graphics rendering, it has now become a core computing component in AI training and high-performance computing due to its strong parallel computing capabilities. There is a strong demand in scenarios such as artificial intelligence and data centers, and breakthroughs in domestic GPUs help solve the “bottleneck” problem in AI computing power.
Automotive Chips
These are chips that meet automotive industry standards (such as reliability, safety, temperature adaptability, etc.) and are used in automotive power systems, autonomous driving, in-car entertainment, and other modules. With the development of electrification and intelligence in automobiles, the demand for automotive chips is rapidly growing, and there is vast potential for domestic substitution.

Past Related Concept Speculation
The concept of semiconductor domestic substitution has long attracted market attention. When favorable policies (such as national big fund investments, semiconductor industry support policies), technological breakthroughs (such as domestic equipment entering the wafer factory supply chain, improvements in domestic chip performance), or industry events (such as overseas semiconductor restrictions, stimulating acceleration of domestic substitution) occur, related stocks are often speculated by funds.
For example, since 2020, as the Sino-US trade friction escalated, semiconductor domestic substitution has become a market mainline, with stocks like North Huachuang, SMIC, and Changdian Technology experiencing multiple rallies due to the logic of being “core targets for domestic substitution”; in 2023, under the AI boom, domestic AI chip companies like Cambrian and Haiguang Information have also been favored by funds due to the dual logic of “AI + domestic substitution.” However, after speculation, stock price trends often revert to the company’s fundamentals. If the company’s technological progress and performance do not meet expectations, stock prices may experience corrections. Investors need to consider fundamental factors such as the company’s technological strength, order situation, and industry position when rationally viewing concept speculation.
