From November 3rd to 5th, the first Munich South China Electronics Show kicked off at the Shenzhen International Convention and Exhibition Center. At this exhibition, SHHX Technology Co., Ltd. brought a variety of new heavyweight silicon carbide products to the show, which attracted the attention of many exhibitors.
SHHX is a high-tech enterprise dedicated to the development and production of third-generation wide-bandgap semiconductor power devices and power modules. It is also the only company in China that can mass-produce automotive-grade silicon carbide MOS tubes and diodes and ship them to world-renowned brands. The customer's high-tech company.
SHHX has always adhered to its own road of independent development in the silicon carbide field and achieved remarkable results. "In fact, in the field of third-generation semiconductor silicon carbide, we have always been in the forefront of the world." SHHX Chairman Xu Fei said in an interview that SHHX has already ranked among the silicon carbide devices in the 2018 Digital Times market research report. It is among the top five in the world.
In terms of independent intellectual property rights, SHHX has nearly 40 global invention patents (US, China, etc.), including device design patents and device process patents. The company has authorized multiple device production process patents to partners and collaborated with them Wafer production and yield increase. This year, the company has applied for nearly ten invention patents at home and abroad to make further arrangements for the intellectual property rights of silicon carbide.
SHHX's R&D personnel account for more than 70%. The core R&D personnel Dr. Li, Dr. Hong and others have been studying silicon carbide-related device design and production processes since 2004. The core team is composed of more than 20 experts who have worked in the semiconductor industry for many years. Composition, the team's research projects cover silicon carbide material research, power device design, wafer manufacturing process, silicon carbide module design and application development.
Through years of deep cultivation and accumulation in the silicon carbide field, in 2014, Hanxin has completed the mass production and vehicle certification of the full range of 650V/1200V silicon carbide Schottky diode products, and the maximum single tube current can reach 100A; mass production in 2017 The full range of 650V/1200V silicon carbide MOS has passed vehicle certification, and the minimum internal resistance can reach 20 milliohms. So far, SHHX has a profound capability of device design and process research and development with independent intellectual property rights, breaking through the monopoly of large foreign manufacturers in silicon carbide technology.
At present, SHHX`s 650V series, 1200V series and 1700V series silicon carbide diodes and MOS tubes have all been mass-produced, and all have passed vehicle-level certification. The 3300V series developed in accordance with the requirements of European new energy car companies have also been mass-produced. Customer verification has been completed and the supply chain is being introduced; at the same time, SHHX uses its own SiC MOS tubes and diodes to design high-power-density modules, and has mass-produced and shipped power modules above 650V, 1200V/100KW.
It is worth mentioning that SHHX also has its own design of the world's only energy-producing SiC JMOS product (successfully integrated silicon carbide Schottky diodes into SiC DMOS components without increasing the area of normal DMOS). By integrating JBS and DMOS devices together, the integrated function of the inverter can be integrated in a single chip. SHHX's innovative JMOS technology can achieve module miniaturization and higher power density. Xu Dong said: "As the company's core product, JMOS will soon be produced in a fab in China."
According to Dr. Li, SHHX’s silicon carbide products have been used by well-known companies at home and abroad. The industries involved include OBC/DC-DC/charging piles for new energy vehicles, photovoltaic inverters, communication power supplies, high-end server power supplies, and energy storage. , Industrial power supply, high-speed rail, aerospace industry, etc.
Regarding the current situation that the company's products are mainly exported overseas, Xu Dong explained that the cost of SiC devices was high before, and Chinese domestic car companies are holding a wait-and-see attitude. Only foreign car companies are "willing" to use it. However, in the past two years, with the increase in China’s domestic demand for import substitution and the decline in the cost of silicon carbide, coupled with the large-scale use of the company’s full range of products in countries such as Europe, America and Asia, more than a dozen car companies in China have also acquired SHHX products. Go for verification. She further stated that the huge scale of China's new energy vehicle market is SHHX's current and future main market.
Talking about future development plans, Xu Dong said: Recently, the policy of the "New Energy Automobile Industry Development Plan" has been officially implemented, and new energy vehicles, charging piles and other fields will open a new growth cycle, and the demand for power semiconductors will greatly increase, especially for performance. Silicon carbide power devices with better performance are in strong demand. According to Yole, the largest application market for silicon carbide comes from automobiles. Compared with traditional solutions, the use of silicon carbide solutions can make the system more efficient, lighter and more compact. With the gradual reduction in the cost of silicon carbide and the continuous expansion of the application side, the future market development prospects are broad. "
