Basic semiconductors: Steady layout, silicon carbide power device business is developing rapidly

Basic Semiconductor was established in Shenzhen in 2016. Tianyancha shows that its registered capital is RMB 35,568,255. Basic Semiconductor is committed to the research and development and industrialization of silicon carbide power devices. Basic Semiconductor has established a world-class R&D and industrialization innovation team to conduct research and development in material preparation, chip design, manufacturing process, packaging and testing of silicon carbide devices, covering all links of the industrial chain.

Dr. He Weiwei, Director and General Manager of Basic Semiconductor, told Jiwei.com: "This year, Basic Semiconductor has made relatively big breakthroughs in product development, market expansion and industrial layout. The company has accelerated the pace of product updates and iterations, continuously optimized product performance, and further enriched product types."

It is worth mentioning that although the entire semiconductor industry was hit by the epidemic in 2020 and the Sino-US trade issues brought greater uncertainty to the semiconductor industry, this also accelerated the pace of domestic substitution, and basic semiconductors also reached a new peak of development under this wave.

The internally insulated TO-220 packaged silicon carbide Schottky diode launched by Basic Semiconductor this year can simplify production steps, improve production efficiency and the long-term reliability of the entire machine, and improve installation process problems that plague industries such as switching power supplies. The newly launched DFN8*8 packaged silicon carbide Schottky diode is suitable for compact design and has lower parasitic inductance than TO-252 and TO-263 packages. It can be widely used in server power supplies, fast charging and other fields. He Weiwei said: "Basic Semiconductor's silicon carbide power devices have performed well in 5G, new energy vehicles, high-efficiency power supplies and other fields. The market coverage and share are also steadily increasing, and have been widely recognized by customers."

At present, in addition to overseas automobile companies such as Tesla, domestic brands such as Xiaopeng Motors and BYD have begun to accelerate the introduction of silicon carbide power devices in their cars. He Weiwei believes that this change in market demand is mainly due to the performance of silicon carbide power devices. "Silicon carbide has advantages such as high frequency, high power density, high voltage, and high temperature resistance. Its application in the field of new energy vehicles will help improve the performance of the entire vehicle. New energy vehicles are one of the most important markets for silicon carbide in the future. Basic Semiconductor is also stepping up its layout in the field of new energy vehicles."

Compared with foreign suppliers, Basic Semiconductor can provide customers with cost-effective products and customized services. The company has built a professional silicon carbide power device engineering laboratory, which is a comprehensive laboratory focusing on R&D design verification, new material technology application, product function testing and reliability testing, with strong localized technical support capabilities. He Weiwei said, "In China, Basic Semiconductor's wafer design and packaging technology are at the leading level in the industry. As early as 2018, we launched a 1200V silicon carbide MOSFET that passed industrial-grade reliability testing. In addition, the company's independently developed silicon carbide diode products have passed the AEC-Q101 automotive-grade certification. Basic Semiconductor's international R&D team for automotive-grade silicon carbide power modules has more than 30 years of module design experience. At the same time, based on its technical accumulation in discrete devices, Basic Semiconductor's automotive-grade full silicon carbide power modules have outstanding advantages in many parameters such as gate input capacitance."

Basic Semiconductor not only focuses on enhancing innovation capabilities, but also pays great attention to product quality control. Basic Semiconductor's full range of silicon carbide discrete devices and modules are tested for reliability in accordance with AEC-Q101 and AQG-324. Products follow automotive standards from design to verification, and a car-grade quality system is created in strict accordance with automotive requirements.

Thanks to product innovation and technological innovation, Basic Semiconductor has maintained a state of rapid growth. Regarding the next step of planning, He Weiwei said: "At present, Basic Semiconductor's wafer production line in Beijing has been put into operation, and the Nanjing epitaxial production line base will be completed and put into production in 2021. For the field of new energy vehicles, Basic Semiconductor's automotive-grade silicon carbide module production line is expected to be put into production in 2021. After completion, the company's manufacturing strength will be greatly enhanced. Starting from the overall and strategic height, Basic Semiconductor will accelerate the layout of various links in the industrial chain to further enhance the competitiveness of the industry, improve the risk resistance of the supply chain, and improve service quality, and strive to build a world-class silicon carbide IDM enterprise."
