Automotive semiconductors refer to semiconductor products used in vehicle body automotive electronic control devices and in-vehicle automotive electronic control devices. According to the types of functions, automotive semiconductors can be roughly divided into main control/computing chips, power semiconductors (including analog and mixed-signal ICs), sensors, wireless communication and vehicle interface chips, vehicle memory and other chips (such as dedicated ASSPs, etc. ) several major types, and with the increase in electrification and intelligent applications, both the number and value of automotive semiconductors are still growing.

In recent years, with the rapid development of automobile electrification, intelligence and networking, the demand for chips in automobiles is also increasing. According to statistics, traditional fuel vehicles generally need about 500 chips, electric vehicles need about 1,500 chips, and high-end smart electric vehicles will need more than 3,000 chips.

The semiconductor supply chain remains fragile, and demand continues to far outstrip supply. The development trend of automobile electrification, networking, and intelligence has driven a substantial increase in the demand for automotive semiconductors. In terms of electrification, power devices, especially IGBTs, benefit the most from vehicle electrification. IGBT is the core device for power conversion and circuit control in electronic devices, and is widely used in electric vehicles, photovoltaics, industrial control and other fields. According to ASMC research, the global IGBT market is expected to reach US$6 billion in 2022 and US$9.2 billion by 2025. With the rapid development of automobile intelligence, autonomous driving and intelligent cockpits have increasing demands on automobile perception devices, computing power, and data volume, and there is broad room for growth in automobile control chips and memory chips. According to IHS data, benefiting from the trend of "three modernizations" in the automotive industry, the global automotive semiconductor market is expected to grow from US$38 billion in 2020 to US$67.6 billion in 2026. The lack of automotive cores promotes the acceleration of the localization of automotive chips, and automotive semiconductors are at the intersection of automobiles and semiconductors, and are expected to usher in a historic development opportunity.

Automotive semiconductors are the core of automotive electronics and are widely used in multiple systems in the body. In automotive electronic components, semiconductors will be the core devices responsible for functional realization. Automotive semiconductors can be divided into microcontrollers (MCU, SoC, etc.), power semiconductors (IGBT, MOSFET, power management chips, etc.), storage (NOR , NAND, Dram, etc.), sensors (pressure, radar, current, image, etc.), and interconnect chips (radio frequency devices), which are used in five major areas: body, instrumentation/infotainment, chassis/safety, powertrain and driver assistance systems plate. Sensors, microcontrollers, storage devices, and power are required in various sectors, while interconnect chips are mainly used in body and information systems.

There are many links in the automotive semiconductor industry chain, and the division of labor is clear. The automotive semiconductor industry chain is the same as consumer electronics. The most downstream is various module manufacturers. In the sensor industry, it is divided into material and equipment manufacturers, chip design manufacturers, chip manufacturers, chip packaging and testing manufacturers, etc. On the whole, automotive semiconductors There are many links in the industrial chain, and the division of labor is relatively clear.

In recent years, Chinese enterprises have integrated overseas high-quality automotive semiconductor assets through acquisitions, opening up growth space for domestic substitution, and becoming the main driving force for the rapid development of my country's automotive semiconductor industry. And some mature companies that have become stronger and bigger in the field of consumer-grade semiconductors are also gradually developing business in the automotive-grade market. At the same time, some domestic traditional auto manufacturers have also begun to focus on the upstream and downstream extension of the industrial chain, and actively deploy the automotive semiconductor industry. In addition, in the emerging fields of automotive semiconductors such as ADAS and intelligent network connection, domestic automotive semiconductor start-ups continue to emerge. External acquisitions, mature companies' layout of automotive semiconductor business, and entrepreneurship in emerging fields have become the main paths supporting the development of my country's automotive semiconductors.

Relying on the national-level new energy vehicle technology innovation platform, it absorbs and integrates advantageous enterprises in all aspects of the domestic new energy vehicle industry chain, and establishes a cross-industry automotive-grade semiconductor innovation application alliance to support design, manufacturing, packaging, testing and application within the alliance. Enterprises in the link carry out R&D and industrialization for the special requirements of automotive semiconductors.
