China's industrial MEMS sensors face three major challenges and four major trends

Today, China, as the world's largest production base for electronic products, is consuming a quarter of the world's MEMS devices. However, at present, most of the MEMS sensors in China still rely on imports. Domestic MEMS sensors are still dominated by low-end and relatively backward technologies. This situation will continue for a long time. Then, how should each MEMS company settle its mentality and face this challenge, so as to find the development opportunities?

Three major challenges: technology research and development, industrial chain competitiveness, and price impact

Chinese MEMS manufacturers face many challenges. First, the lack of high-end R&D personnel and experienced local MEMS engineers has led to backward basic research. At the same time, the commercialization of MEMS sensors has a long application cycle and the development of MEMS sensors takes longer. This poses a great challenge to the patience and foresight of MEMS companies.

On the other hand, China's MEMS industry chain is still relatively weak in terms of competition, and has not produced companies with leading positions in the international market. MEMS sensors, like IC chips, have a strong scale effect, and domestic companies cannot afford shipments. As a result, the entire industrial chain, such as the front-end tape, has poor processing capability, and the consistency and repeatability of production cannot meet the design and processing requirements. Claim. Therefore, the entire MEMS industry chain is in the investment phase, making profitability more difficult and creating a vicious cycle.

System manufacturers demand large quantities of MEMS products

In addition, falling prices have made it difficult for MEMS manufacturers to make profits. The price of MEMS sensor products is not directly proportional to the importance of the product or the difficulty of development. For example, according to statistics, from the point of view of the widely used and highly competitive gyroscopes and accelerometer markets, prices have fallen by 3% to 5% per quarter. System manufacturers have a large demand for MEMS products, but they also have already killed prices. It is difficult for MEMS manufacturers to continue.

Four major trends: new devices, new applications, disruptive technologies, new designs

Faced with these challenges, how can domestic MEMS manufacturers establish confidence and seek opportunities?

First of all, we must admit that China is the largest country in electronics production and consumption, and the end consumer market is huge. This advantage should give certain MEMS makers certain confidence. And driven by the Internet of Things market, the market growth of MEMS sensors will be considerable. In addition, MEMS sensors have a variety of products and there is also huge room for innovation.

MEMS sensor manufacturing relies on advanced semiconductor micromachining technology

On the other hand, depending on the characteristics of MEMS sensors, MEMS sensors have always relied on semiconductor-based micromachining to fabricate devices to replace more complex, cumbersome, or insensitive sensors. Based on this, there will be four major trends in the future to change the MEMS market structure. They are: emerging devices, new applications, disruptive technologies, new designs.

Simply put: emerging devices such as micro-mirrors and environmental sensors; new applications such as pressure sensors for position or height sensing; disruptive technologies, including packaging, new materials such as piezoelectric films and 300mm/12-inch crystals Round; new designs include NEMS electromechanical systems and optical integration technologies.

The Internet of Things is China's core development strategy for the next decade, and MEMS sensors are an indispensable part of the Internet of Things. In the next decade, MEMS products that are far more promising than current mainstream MEMS sensors will emerge, and look forward to China. The MEMS industry ranks among the top in the world.
