Want to use more than ten kinds of sensors, a smartphone may be applied in a premium car hundreds of sensors, the intelligence of a modern factory easily at the number of sensors used in tens. The sensor has penetrated into every aspect of people production and living.

Ccid consulting forecasts, "much starker choices-and graver consequences-in" period, the average annual compound growth rate CAGR sensor market in China will reach more than 31%. And according to the third industrial revolution "and" zero marginal cost of society, the author Jeremy rifkin's bold guess, by 2030, the global number of sensor applications will be from 2013 in 3.5 billion by leaps and bounds to more than 100 trillion, are closely connected with the natural environment will be through the sensor.

"Sensor is to promote our country modern information technology, driving the development of industrialization of the best breakthrough." Member of Chinese academy of sciences, Chinese academy of sciences, Shanghai institute of microsystem and information technology director wang xi said, "in the global semiconductor industry, started relatively late sensor as a whole, the gap between our country and abroad is small, and now is the crucial period of transition from tradition to the new sensor, masterfile corner overtaking can be realized."

In the high-end sensor imports accounted for 80%

According to industry estimates, the sensitive element and sensor, 2014 sales exceeding 120 billion yuan; Demand will reach about 65.29 billion, 2015 growth rate above 18%, sales will exceed 130 billion yuan. At present, the existing more than 1700 engaged in the sensor development, production and application of the enterprises and institutions, sensor products up to 10 major categories, 42 small classes, more than 6000 varieties.

China's sensor industry has formed from the technical research and development, design, production and application of a complete industrial system, part of the niche has firmly established itself as one of the world leading level. But in terms of overall level, domestic sensor products still give priority to with mid-range, technology is relatively backward. Imports of high-end sensor in the Chinese market accounted for 80%, digital, intelligent, serious lack of product miniaturization.

"Domestic enterprise's products are mainly concentrated in the low pressure, low value-added products, such as temperature, strain gauge, in recent years, there were several companies started in MEMS products, the microphone products a good momentum of development, but others such as pressure, acceleration, gyro is also relatively low-end products."

Professor of tsinghua university institute of microelectronics nimo Yao in an interview with "China electronics news" reporter said, "compared with Europe and the United States, the domestic in every link of the whole industry is backward, manufacturing technology and packaging technology. Basic step of problem solving is not thorough, original innovative products, leading to the added value of products and market share is low."

"In the process of developing the sensor industry in China in the lack of technology development and industrialization development professionals, industry culture and industrialization does not adapt, market adaptability and high fitting degree is not high and the comprehensive cost, insufficient ability to dock with the international market, the enterprise system and mechanism is restricted, and many other problems. From the point of the industry as a whole, concentrated expression of a" loose "words." Development research center of industry and information technology, the electronic components industry, chief engineer Guo Yuan pointed out.

The Internet of things and

Sensor is expected to be overtaking "corner"

Sensor is an important part of iot perception layer, undertaking the important task of data acquisition and transmission, the Internet of things is the basis and prerequisite. Data show that global Internet of things the size of the market is expected to reach $11 trillion in 2025, the corresponding sensor market scale will reach hundreds of billions of dollars.

Wang xi believed that the whole semiconductor industry will be benefited from the development of the Internet of things. Although semiconductor industry started relatively late in China, the rapid development of Internet of things, not only let the semiconductor industry in China has a larger market space, but also brought to catch up with the international advanced level, do the world's first opportunity.

Sensor industry as a whole started relatively late, the gap between our country and abroad is small, and now is the crucial period of transition from tradition to the new sensor, masterfile overtaking "corner" can be realized.

Because the Internet of things of the required amount of sensor chip just do simple data acquisition, storage and transport, which requires the chip must be low power consumption and low price. With the aid of the existing materials, packaging technology, the performance on 45 nm chip can be perfect. And around 45 nm process in our country and 8 inch wafer on the mature industry layout, with the development of the Internet of things, the capacity will be released to a great extent.

So, on the one hand, the Internet of things of very large scale market will greatly boost the development of integrated circuit industry; The characteristics of the Internet of things, on the other hand, the sensor is expected to change the development path of integrated circuits, for existing process of integrated circuits have more play space, this is a great opportunity for the development of China's integrated circuit.

In fact, the sensor industry not only contains a huge market, but also closely related to the national information security. Sensor as an important external information source and information on the Internet of things connected basis, also become one of the vulnerable link. If there is mistake, not only may lead to problems such as data leaks and network intrusion, are more likely to be false data into the network impact all subsequent application. Realize the sensor independently controlled and safe and reliable, also guarantees the information security is an important part of missing.

Industrial chain should be coordinated development

Experts point out that, due to the sensor industry across multiple fields, belong to different industries and departments management for a long time, the industry management is too scattered, lack of unified coordination mechanism, industry policy formulated by the competent department of the sensor industry development, the scope of control for different will inevitably have limitations. Countries for a long time for the industry development policy, the lack of strategic planning based on the height of the whole industry chain, unable to meet the domestic demand for high-speed development of industry.

Therefore, Guo Yuansheng suggested that the government's response to sensor industry repositioning and establish development goals, the top design, combined with industry characteristics to develop the industrialization development of medium and long-term strategic planning, introduced its continuity industry development policy, strengthen the industry macro guidance, promote industrial innovation ability of ascension together. To reasonable industry structure adjustment and industry layout, and create conditions for industry sustainable development.

Aimed at the development measures of the industry, nimo Yao said, because the types of sensors, the difference is big, so difficult to by a contract mode to promote the progress of the whole industry. From the point of the development of sensor industry abroad, the main several companies from the specific product breakthrough, including design, manufacture, packaging, signal processing, etc., by an enterprise the whole technique to understand, then around based on similar technology products, then gradually expand product variety and size. Although there are a few companies such as American company, they have no production line, completely dependent on OEM grow into big companies, but they has original innovation in structure design and packaging, can be developed.

Nimo Yao stressed that if there is no unique in the link of the design, manufacture and packaging innovation technology, we must put the manufacturing process, noise suppression, encapsulation and readout circuit, etc. The main technical link to fully grasp and breakthrough, before you can rely on cost advantage for competition; High value-added products must rely on the innovation of the primitiveness, including design, manufacturing and packaging, etc. One or more links.

R&d spending also is a big pain points for the development of sensor industry. Significant difference between the sensor and the traditional IC is variety and individuation, between different devices not standard of process, involving different parameters, lead to each series of products are from the front back into r&d, the prior development requires a lot of money and time. At the same time, the high end MEMS devices rate is about 70% ~ 70%, and the need to through a lot of data to a stable process, long-term improvements and running-in process also requires constant input.

, micro-nano electronics research institute of Beijing university, director of the recommendations to the "China electronics news" reporter huai-lin liao, shall establish a neutral country sensor research and development center, relying on the unit, funds, venture funds, enterprise investment by the state to fully market-oriented operation, the key to solve enterprise research and development ability, weak, inadequate research and development or high risk, scientific research units difficult issues such as technology transfer.

"Can be according to certain proportion into the related project, such as enterprise and research and development center". Enterprise can get priority project industrialization, research and development center under the condition of the enterprise have profit can be authorized by industry returns." Huai-lin liao, "project can be selected through its own technical committee by the research and development center, also can come from enterprises or commissioned by a set of scientific research units to techniques. And let research unit personnel reserve personnel relationship, industrialization development with technology to the research and development center organization."
