Standing at the outlet of IOT, can China's sensor industry overtake in the corner

a dozen kinds of sensors are used in a smart car. Hundreds of sensors may be used in a high-end car. The number of sensors used in a modern smart factory is often tens of thousands. Sensors have penetrated into all aspects of people's production and life

CCID consultants predict that during the 13th Five Year Plan period, the CAGR of China's sensor market will reach more than 31%. According to Jeremy Rifkin, the author of the third industrial revolution and the zero marginal cost society, by 2030, the number of sensors applied worldwide will soar from 3.5 billion in 2013 to more than 100 trillion, and human and natural environment will be closely connected through sensors

sensors are the best breakthrough to improve China's modern information technology and drive the development of industrialization. Wang Xi, an academician of the Chinese Academy of Sciences and director of the Shanghai Institute of microsystems and information technology of the Chinese Academy of Sciences, said that in the global semiconductor industry, sensors as a whole started late, and the gap between China and foreign countries is small. Now, it is the key stage of the transformation from traditional sensors to new sensors. If the layout is appropriate, it is possible to overtake on curves

the import of medium and high-end sensors accounts for 80%

according to industry statistics, the sales of sensitive components and sensors in China exceeded 120billion yuan in 2014; In 2015, the demand will reach about 65.29 billion, with a growth rate of more than 18%, and the sales volume will exceed 130 billion yuan. At present, there are more than 1700 enterprises and institutions engaged in the research, production and application of sensors in China, and the sensor products have reached 10 categories, 42 sub categories and more than 6000 varieties

China's sensor industry has formed a complete industrial system from technology research and development, design, production to application, and some subdivisions have reached the world's leading level. However, in terms of the overall level of sometimes adopting casting structure (cast steel, cast aluminum, etc.), domestic sensor products are still mainly medium and low-end, and the technology is relatively backward. The import of medium and high-end sensors in the Chinese market accounts for 80%, and there is a serious shortage of digital, intelligent and miniaturized products

the products of domestic enterprises are mainly concentrated in low-end pressure, temperature, strain gauge and other low value-added products. In recent years, several enterprises have begun to produce MEMS products, among which microphone products have a good momentum of development, but other products such as pressure, acceleration, gyroscope and so on are also relatively low-end products

in an interview with China Electronics News, Professor Wang Jianyao of the Institute of microelectronics at Tsinghua University said that compared with Europe, America and Japan, China is backward in all aspects of the entire industry, and the manufacturing technology and packaging technology are more obvious. The problem of basic links is not solved thoroughly, and there are few original innovative products, resulting in low added value and market share of products

in the development process of China's sensor industry, there are many problems, such as the lack of technical development and industrialization of the method of developing annual inspection and calibration testing machine, professional talents, industry culture and industrialization are not compatible, market adaptability and fitting degree are not high and the comprehensive cost is too high, the ability to connect with the international market is not enough, and the enterprise system and mechanism are seriously restricted. From the perspective of the industry as a whole, it is concentrated as a loose word. Guoyuan, chief engineer of the electronic component industry development research center of the Ministry of industry and information technology, pointed out

IOT sensor is expected to overtake in corners

sensor is an important part of IOT sensing layer, which undertakes the task of data collection and transmission, and is installed on the vehicle at will. It is the foundation and premise of IOT implementation. According to the data, the global IOT market is expected to reach US $11trillion in 2025, and the corresponding sensor market will also reach hundreds of billions of US dollars

Wang Xi believes that the entire semiconductor industry will benefit from the development of IOT. Although China's semiconductor industry started late, the rapid development of IOT has not only given China's semiconductor industry more market space, but also brought opportunities to catch up with and surpass the international advanced level and become the world's first

the sensor industry as a whole started late, and the gap between China and foreign countries is small. Now, it is the key stage of the transformation from traditional to new sensors. If the layout is appropriate, it is possible to overtake on curves

because a large number of sensor chips required by IOT only need to complete simple data acquisition, storage and transmission, which requires low power consumption and low price. With the help of existing materials and packaging technology, these properties can be perfectly presented on 45nm chips. However, China has a mature industrial layout in the 45nm process and 8-inch wafer. With the development of IOT, these capacities will be released to the greatest extent

therefore, on the one hand, the super large market of IOT will greatly stimulate the development of the integrated circuit industry; On the other hand, the characteristics of the sensors required by IOT are also expected to change the development path of integrated circuits, giving more room to play to the integrated circuits of existing processes, which is a great opportunity for the development of integrated circuits in China

in fact, the sensor industry not only contains a huge market, but also is closely related to the safe and reliable information security during national operation. As an important source of external information and the basis of IOT information interconnection, sensors have also become one of the vulnerable links. If there is a flash, it may not only lead to data leakage and network intrusion, but also introduce false data into the network and impact all subsequent applications. Realizing the self-control, safety and reliability of sensors is also an important part to ensure the information security of our country

the industrial chain needs coordinated development

experts pointed out that because the sensor industry spans many fields and has been managed by different industries and departments for a long time, the industrial management is too decentralized and lacks a unified coordination mechanism. The sensor industry development policies formulated by the competent departments of various industries will inevitably have limitations due to different management ranges. The industrial development policies issued by the state for a long time lack strategic planning based on the height of the whole industrial chain, and cannot meet the domestic industrial demand of rapid development

for this reason, Guo Yuansheng suggested that the government should reposition the sensor industry and establish development goals, carry out top-level design in combination with industry characteristics, formulate medium and long-term strategic planning for industrialization development, issue sustainable industrial development policies, strengthen industrial macro guidance, and promote the improvement of industrial collaborative innovation ability. Carry out reasonable structural adjustment and industrial layout of the industry to create conditions for the sustainable development of the industry

for the specific development measures of the industry, Wang Jiyao said that due to the large variety and differences of sensors, it is difficult to promote the progress of the whole industry through the mode of one OEM. In terms of the development of foreign sensor industry, several major enterprises have made breakthroughs in specific products, including design, manufacturing, packaging, signal processing, etc. one enterprise understands the whole technology chain, and then gradually expands the product category and scale around products based on similar technologies. Although a few enterprises, such as invensense in the United States, have no production lines and rely entirely on OEM to grow into large enterprises, they can only develop with primitive innovation in structural design and packaging

Wang Jiyao stressed that if there is no unique innovative technology in the design, manufacturing and packaging links, we must fully grasp and make breakthroughs in the main technical links such as manufacturing process, noise suppression, packaging and readout circuits, and then we can rely on cost advantages to compete; High value-added products must rely on original innovation, including one or more links such as design, manufacturing and packaging

R & D investment is also a major pain point in the development of the sensor industry. The major difference between sensors and traditional ICs is that they are diverse and personalized. There is no fully standard process between different devices, involving different parameters, resulting in the reinvestment of each series of products from the front-end research and development. Therefore, the early research and development requires a lot of money and time. At the same time, the yield of medium and high-end MEMS devices is about 70% - 80%, which requires a large amount of data to stabilize a process, and long-term improvement and running in processes also need continuous investment

in this regard, liaohuailin, director of the Institute of micro nano electronics of Peking University, suggested to China electronic news that a neutral and independent national sensor R & D center should be established, which should be fully market-oriented with the investment of national funds, venture funds and enterprises, focusing on solving the problems of weak R & D capacity of enterprises, insufficient R & D investment or high risk, and difficulties in technology transfer of scientific research institutions

relevant projects can be invested in a certain proportion, such as enterprises and R & D centers 1:10. Enterprises can obtain the priority of project industrialization, and the R & D center can obtain returns through industrial authorization when the enterprise is profitable. Liaohuailin proposed that the project can be selected by the R & D center through its own technical committee, or it can be a complete set of technology entrusted by enterprises or transferred by scientific research institutions. Moreover, we might as well let the personnel of scientific research institutions retain personnel relations and take technology to the R & D center to organize industrial development
