According to the announcement, Zhuzhou CRRC times Semiconductor Co., Ltd., the holding subsidiary of the company, plans to invest 462 million yuan to improve the technical capacity of silicon carbide chip production line, with a construction period of 24 months. After the completion of the project, the technical capacity of the existing planar gate sicmosfet chip will be improved to meet the R & D capacity of grooved gate sicmosfet chip, the existing 4-inch SiC chip line will be increased to 6 inches, and the annual capacity of the existing 4-inch SiC chip line will be increased from 10000 pieces / year to 25000 pieces / year of 6-inch SiC chip line.
According to the power SiC 2022 report recently released by yole, a market research and strategy consulting company, the SiC device market is expected to exceed US $7 billion by 2027, an increase of US $6 billion over US $1 billion in 2021. This multi billion dollar business will attract more manufacturers to join it and usher in a new round of capacity expansion and supply chain integration in the future.
Zhuzhou Crrc Times Electric Co.Ltd(688187) said that the construction of the project is an important measure based on the company’s development strategy and market demand, which is in line with the development direction of national policies. The implementation of the project is conducive to further expand and enhance the competitiveness of enterprises and bring new development opportunities for the development of the company’s silicon carbide industry. At the same time, after the completion of the project, the company’s process platform capacity, product R & D capacity and production and manufacturing capacity will be further improved. In the long run, it will play a positive role in the company’s business layout and operating performance.
comprehensively improve the autonomy of the third generation semiconductor key chips
Public information shows that Zhuzhou Crrc Times Electric Co.Ltd(688187) is mainly engaged in the R & D, design, manufacturing, sales and provision of relevant services of rail transit equipment products, with an industrial structure of “device + system + complete machine”. At the same time, the company carries out business in the fields of power semiconductor devices, industrial converter products, electric drive system of new energy vehicles, sensor parts, marine engineering equipment and so on.
In response to the national requirements and the company’s overall development strategy, the company’s semiconductor industry is committed to building an independent core technology of advanced power semiconductor devices, relying on a strong application and industrial platform, strengthening the complete industrial chain of “chip module component device system”, and forming a virtuous circle in which device technology promotes device progress and device technology drives device technology.
In the field of power semiconductor devices, the company has built an industrialization base of 6-inch bipolar devices, 8-inch IGBT and 6-inch silicon carbide, and has a full set of independent technologies for chips, modules, components and applications. Among them, the whole series of high reliability IGBT products produced by the company have broken the monopoly of foreign enterprises in the core devices of rail transit and key devices of UHV transmission project. At present, the problem of autonomy of Shanxi Guoxin Energy Corporation Limited(600617) automobile core devices is being solved.
The announcement disclosed that after the implementation of the project, a SiC chip mass production line facing the direction of new energy vehicles and rail transit will be formed, and high-performance new products will be further developed, which can further promote the progress of semiconductor technology in the CRRC era, improve the industrialization level, realize the autonomy of national third-generation semiconductor key chips, enhance international competitiveness and ensure the sustainable development of the third-generation semiconductor industry.
high downstream demand and broad market space
Yang Jungang, senior analyst of CCID Consulting, believes that the growth of SiC market mainly comes from the increase of market demand. Due to its wide band gap, breakdown field strength and strong thermal conductivity, it is mainly used in power supply, new energy vehicles, motor drive, photovoltaic and energy storage. With the implementation of national strategies such as double carbon economy and new infrastructure, the use of SiC will be further increased, and some products will change from silicon to SiC.
In 2019, in China’s SiC and Gan power electronic device application market, consumer power supply was the largest application, accounting for 28%, followed by industrial and commercial power supply, accounting for 26%, and new energy vehicles ranked third, accounting for 11%.
In the future, as the cost of SiC and Gan products decreases, the cost performance advantage begins to highlight, and there will be more application scenarios. In particular, with the rapid development of new energy vehicles, SiC ushered in a good opportunity for development. The application of SiC in new energy vehicles can reduce the loss, reduce the volume and weight of modules and improve the endurance.
Relevant data predict that by 2025, the global number of new energy vehicles is expected to reach 11 million, with China accounting for 50%. New energy vehicles need to add a large number of power semiconductors. 48V light hybrid needs to increase by more than $90, and electric or hybrid needs to increase by more than $330. If SiC devices are used, the value of single vehicle will increase more. Therefore, with the decline of cost and the gradual maturity of technology, SiC has a large application space in new energy vehicles.
original production line of will lay a good foundation for the successful production of project
In fact, Zhuzhou Crrc Times Electric Co.Ltd(688187) as early as the 13th Five Year Plan period, the silicon carbide chip line was built. At present, this not only solves the company’s breakthrough in the field of silicon carbide technology from scratch, but also lays a good foundation for this upgrading.
For example, the company thus has a good technical foundation. The company has applied for a number of invention patents and published many papers in the field of silicon carbide devices, completed the development and technical accumulation of the first generation of technical products, and formed a complete ability of mature SiC chip products “design manufacture test module”. The company’s SiC products have achieved application demonstration in subway, new energy vehicles, photovoltaic and other market fields.
The company has fully mastered planar gate (DMOS +) technology, trench gate (TMOS) technology and fine trench (rtmos) technology. The company has an industrialization base of 6-inch bipolar devices, 8-inch IGBT and 6-inch silicon carbide, and has a full set of independent technologies for chips, modules, components and applications. In addition to the wide application of bipolar devices and IGBT devices in power transmission and distribution, rail transit, new energy and other fields, the company’s project of “product development and application verification of high-performance SiC SBD and MOSFET Power electronic devices” has passed the appraisal of scientific and technological achievements, Five representative varieties of high-performance SiC SBD and three representative varieties of SiC MOSFET have been realized, and some products have been applied.
It can be said that the perfect project construction system owned by the company is an important guarantee for the success of the project. The company has experience in the construction of many industrialized semiconductor production lines. The technical team has rich experience and ability in project organization, sound project implementation organization, complete project management system and perfect fund control system, which can be fully competent for the construction of this project.
On the whole, with the maturity of 6-inch SiC wafer manufacturing technology, the quality and stability of its related products are gradually improved, which drives the purchase demand of foreign downstream device manufacturers for SiC wafers from 4 inches to 6 inches, and the mainstream trend of 6-inch silicon carbide is obvious.
The Zhuzhou Crrc Times Electric Co.Ltd(688187) improvement of the technical capacity of silicon carbide chip production line better conforms to the general trend of industry development, which can not only better meet the explosive demand of downstream new energy, photovoltaic and energy storage, greatly increase the company’s performance, but also improve the autonomy of national third-generation semiconductor key chips and accelerate the promotion of domestic substitution.
