Wuxi Guojing Micro Semiconductor Technology Co., Ltd. is a high-tech innovative enterprise engaged in the research and development and industrialization of wide-bandgap third-generation semiconductor silicon carbide SiC power devices, ammoniated GaN optoelectronic devices and conventional integrated circuits. It is engaged in silicon carbide field effect tubes. It designs, produces and sells silicon carbide Schottky diodes, GaN optoelectronic optocoupler relays, microcontroller integrated circuits and other product chips and provides related product overall solution design supporting services. It is headquartered in the High-tech Development Zone of Wuxi City, Jiangsu Province, and has offices in Hangzhou, There are R&D centers and sales service support centers and offices in Shenzhen and Hong Kong. The company has leading domestic R&D capabilities and focuses on providing customers with high-efficiency, low-power consumption, low-resistance, and stable-quality silicon carbide high and low-power devices and optoelectronic integrated circuit products, while also providing one-stop application solutions and on-site technology. Support services that enable customers’ systems to have high performance, flexibility, reliability, and cost competitiveness. The company's silicon carbide power devices cover 650V/2A-100A, 1200V/2A-90A, 1700V/5A-80A and other series. The products have been put into mass production, and the products can fully benchmark the advanced quality and level of international brand peers. It has successively launched full-current and voltage-grade silicon carbide Schottky diodes and silicon carbide MOSFET series products that have passed industrial-grade and automotive-grade reliability tests. Their performance has reached the international advanced level and is used in solar inverter power supplies, new energy electric vehicles and charging piles. , smart grid, high-frequency welding, rail transportation, industrial control special power supply, national defense and military industry and other fields. Due to its high-speed switching and low on-resistance characteristics, it can exhibit excellent electrical characteristics even under high temperature conditions, significantly reducing switching losses, making components smaller and lighter, more efficient, and improving the overall reliability of the system. , which can increase the cruising range of electric vehicles by 10%, reduce the weight of the vehicle by about 5%, and enable safe and stable operation in high-temperature environments where charging piles are designed. Especially in high and low voltage optocoupler semiconductor technology, it has an industry-leading R&D team. It pioneered the design and development of 28nm photosensitive grating switch PVG chip technology in China, and successfully mass-produced photoelectric coupling relay chips for 60V, 400V, 600V high and low voltage, low internal resistance, and low capacitance, covering 1500kVrms SOP ultra-small packaging and 3750kVrms isolation. Enhanced conventional SMD, DIP and other packages, single-channel, dual-channel, hybrid dual-channel, normally open and normally closed circuit products, including 200V SOI MOS/LIGBT integrated chips, 100V CMOS/LDMOS integrated chips, 8bit and 32bit microcontrollers, etc. Integrated circuit products have all obtained new product certification from the market and key scientific research units and testing institutions. Most of the engineers in the company's core R&D team have master's degrees or above, and several PhDs are in charge of project development. The company has established a standardized system for technological innovation and intellectual property management, accumulated many core technologies in circuit design, semiconductor device and process design, reliability design, device model extraction, etc., and has a number of international and domestic independent invention patents.
