40 domestic sensor chip manufacturers survey statistics report

release time:2022-03-08Author source:SlkorBrowse:345

In electronic and electrical equipment, sensors are used to acquire the original physical signals from the outside world, including sound, image, temperature, humidity, pressure and light signals, etc., and convert these physical signals into electrical signals, typically in the form of voltage/current. Traditional physical and chemical sensors only acquire external signals and do not have computing and processing capabilities. MEMS sensors based on microelectromechanical systems (MEMS) processes are becoming more and more popular as manufacturing process technology, size, and cost requirements increase.


Among the wide-ranging applications of sensors, smartphones deserve special attention. Both CMOS image sensor (CIS) and touch/fingerprint recognition chip manufacturers have gained huge opportunities for development. Among them, domestic representative manufacturers include OmniVision, Grid Kewei, Huiding Technology. In addition, some smart sensor startups based on scientific research and academic achievements are also worthy of attention. Their technological breakthroughs in lidar, optoelectronics and human sensing have also won the favor of venture capital.


MEMS sensor


MEMS is the abbreviation of Micro-Electro-Mechanical System, which is a system that integrates micro-circuits and micro-machines on a chip according to functional requirements. MEMS is based on traditional semiconductor technologies such as lithography and corrosion, integrated with ultra-precision machining, combined with the knowledge and technical foundations of mechanics, chemistry, optics and other disciplines, so that a millimeter or micron-scale MEMS has precise and complete mechanical, chemical, optical, etc. feature structure. MEMS devices can be mainly divided into MEMS sensors and MEMS actuators, where sensors are devices used to detect and detect physical, chemical, biological and other phenomena and signals, while actuators are used to realize mechanical motion, force and torque and other behaviors.

Figure 1: The working principle of MEMS sensor


MEMS sensor is a miniature sensor manufactured by microelectronics and micromechanical technology. It converts the input signal and derives another monitorable signal through the micro sensor element and transmission unit. Compared with the sensor manufactured by the traditional process, it has the characteristics of small size, light weight, low cost, low power consumption, high reliability, suitable for mass production, easy integration and realization of intelligence. Generally, the size of a single MEMS sensor is measured in millimeters or even micrometers. At the same time, the miniaturized mechanical components have the advantages of small inertia, high resonance frequency, and short response time.

Figure 2: China's MEMS market structure in 2019 by application


According to Yole's statistics and forecasts, the global MEMS market size in 2019 will be 11.5 billion US dollars. In 2020, the market growth will slow down due to the global new crown epidemic. From 2021, the market will resume growth. It is expected that the market will reach nearly 17.7 billion by 2025. USD, with a CAGR of 7.4% from 2019 to 2025.


In terms of product structure, the top five MEMS sensor segments are radio frequency, pressure, microphone, accelerometer and gyroscope, accounting for nearly 65%. According to Yole's forecast, the MEMS sensor segments with a market size of more than $1 billion in 2024 include radio frequency, inertial combination, ultrasonic fingerprint, pressure, microphone and inkjet printing.


From the perspective of application terminals, driven by the Internet of Things and mobile phone 5G replacement, the global consumer MEMS market is expected to grow from US$6.87 billion in 2019 to US$11.14 billion in 2025; driven by the increase in the penetration rate of smart cars , the automotive MEMS market size is expected to grow from $2.18 billion in 2019 to $2.6 billion in 2025, with a CAGR of 3% during the period. In addition, market demand in the industrial, medical, communications, defense, and aerospace fields is also increasing.



China has been the fastest growing market for MEMS in the past five years. According to statistics from CCID Think Tank, the Chinese market size in 2019 is about 60 billion yuan, accounting for about 54% of the global market; the domestic market continues to grow faster than the world, and it is expected that China's MEMS market will exceed 100 billion yuan in 2022.

Figure 3: China is the fastest growing MEMS market in the past five years


In 2019, the top ten manufacturers in China's MEMS market were Broadcom, Bosch, STMicroelectronics, Texas Instruments, QORVO, Hewlett-Packard, Knowles, NXP, Goertek and TDK, of which US companies accounted for 54%. The Chinese company Goertek squeezed into the top ten, and AAC Technology ranked 22nd. At present, the overall scale of domestic MEMS sensor manufacturers is not large. Except for Goertek and AAC, whose annual revenue is more than 100 million US dollars, the annual revenue of local MEMS sensor manufacturers such as MEMSIC, Mattel Technology, and Xinao Microelectronics are all below 60 million US dollars, and the overall scale is small.


my country's domestic supply capacity is insufficient, especially high-end products are almost entirely supplied by imports, and 80% of chips rely on foreign countries; the remaining share is only concentrated in the hands of a few listed companies, such as Goertek, Crystal Optoelectronics, Hanwei Electronics, Silan Five companies including Micro and Jinlong Electromechanical occupy more than 40% of the domestic MEMS market; 70% of the domestic MEMS companies are small and medium-sized enterprises, and their products are mainly concentrated in the low-end and middle-end products. In general, the current status of my country's MEMS sensor companies is that the competition in low-end products is fierce, but there is no competitiveness in the competition of high-end products.


Since the MEMS industry is the basis for the development of science and technology in the new era, and policy support is strong, China's MEMS industry investment and financing cases are increasing year by year, both in terms of quantity and amount. In terms of amount, the investment amount in 2019 is about twice that of 2018. Although the overall investment in the primary market is cold, the investment in the MEMS industry has continued to grow.


From the perspective of subdivisions, the four fields of MEMS+AI, RF MEMS, optoelectronic MEMS, and biological MEMS have the largest number and amount of investment cases. The substantial increase in the number and amount of investment indicates that the capital market is paying more attention to the MEMS industry. In terms of geographical distribution, Beijing, Guangdong, Shanghai, Zhejiang and Jiangsu topped the list in terms of the number of investment cases.

Epilogue


Although there are many domestic sensor and MEMS chip manufacturers, most of them compete in the low-end market. In addition to the relatively concentrated sensor manufacturers of image sensors and fingerprint recognition for the smartphone market, other sensor manufacturers for industrial control and monitoring, vehicle transportation and energy are relatively scattered, and their comprehensive strength and market positioning are not particularly prominent. In the field of automotive electronics and the emerging Internet of Things market, startups centered on smart sensors and lidar technology will usher in greater development space with the support of venture capital and local governments.
