Original title: Get rid of import dependency!BYDSetting up a semiconductor company: “China Chip” is amazing
According to data from Tianyancha, on January 19, Shenzhen BYD Microelectronics Co., Ltd. added foreign investment and established Changsha BYD Semiconductor Co., Ltd., which holds 100% of the shares.
Changsha BYD Semiconductor Co., Ltd. has a registered capital of 20 million yuan. The legal representative is Chen Gang. Its business scope is the manufacture of semiconductor discrete devices, integrated circuits, lighting, LED displays, security monitoring, and smart street lights; integrated circuit testing; and smart city-related services.
According to data, Shenzhen BYD Microelectronics Co., Ltd. was founded in 2004 and isBYD Co., Ltd.A wholly-owned subsidiary of the company, the legal representative of which is Chen Gang, has a registered capital of 40 million yuan. The main business projects are integrated circuit design and production and sales of large-scale integrated circuits, new electronic components and related accessories; production and operation of insulated bipolar transistor modules; and production and processing of LED light-emitting diode packaging and camera modules.
BYD has been committed to the development of the field of microelectronics semiconductors in recent years. It began to lay out the IGBT industry as early as 2005. IGBT is the full name of “insulated gate bipolar transistor” and is mainly used in inverters and other inverters. For electric vehicles, the support of the IGBT system can control the conversion of DC and AC in the drive system, while also controlling the frequency of the AC motor, which directly affects the maximum output power and peak torque of the vehicle.
IGBT chip wafers
In December 2008, BYD officially released IGBT 4.0 technology, breaking the current situation where it was previously monopolized by European, American, and Japanese companies, and even surpassed the products of mainstream companies such as German semiconductor giant Infineon in terms of many key indicators such as current output, comprehensive loss, and temperature cycle life.
At the same time, BYD also announced that it will deploy SiC (silicon carbide), a third-generation semiconductor material with better performance.
By the end of 2018, IGBT 4.0 had been successfully developed, and the production capacity had reached 50,000 pieces, and external supply had been achieved. The establishment of Changsha BYD Semiconductor Co., Ltd. this time may be to further develop IGBT technology-related business.
