MEMS is a multi-disciplinary complex system. The whole industrial chain involves design, manufacturing, packaging and testing, software and application. The upstream of the MEMS industry chain is responsible for the design of MEMS devices, the supply of materials and production equipment. The midstream produces MEMS devices, and the downstream uses MEMS devices to manufacture terminal electronic products.

The whole industry chain of MEMS is complex, involving many manufacturers; China’s design, manufacturing, packaging and testing manufacturers are actively layout MEMS, and have formed a complete MEMS industry chain.

1. Global MEMS manufacturers

The top ten MEMS manufacturers in the world mainly include Bosch, STMicroelectronics, HP, Texas Instruments, Canon, invensense, Avago and qorvo, Lou’s electronics, Panasonic, etc. Bosch, because of its dual layout in automotive electronics and consumer electronics, firmly occupies the first position in the industry, and its revenue accounts for about one third of the total revenue of the five major companies.

Most of the major manufacturers in MEMS industry are fabless, such as Lou’s, HP, Canon, etc. At the same time, parallel IDM manufacturers are also vertically involved in all aspects of the whole industrial chain, such as Bosch and St, which have their own wafer OEM production lines.

There are two main types of MEMS OEM: MEMS OEM provided by IDM manufacturer, MEMS OEM provided by independent OEM, including IC OEM and pure MEMS OEM. In recent years, fabless mode MEMS device manufacturers have developed rapidly. Independent MEMS manufacturers are striving to seek standardized processes to improve economies of scale, reduce manufacturing time and cost, which makes independent MEMS manufacturers grow rapidly. However, IDM OEM is still in the leading position in the market.

3. MEMS packaging test

At present, the international manufacturers with MEMS packaging and testing capabilities mainly include Sunmoon, anrely, silicon products, Licheng technology, etc., while the domestic manufacturers include Huatian technology, Changdian technology, Jingfang technology, etc. Although the domestic MEMS front-end manufacturing still lags behind the international manufacturers, because the domestic packaging technology started earlier, the domestic MEMS industry chain back-end packaging is relatively perfect.

China’s MEMS industry

From the perspective of product use field structure, there is a significant gap between domestic MEMS companies and foreign companies in business scale, technical level, product structure, and 60% – 70% of the design products are concentrated in traditional fields such as accelerometer and pressure sensor. Process development is the most important problem in China’s MEMS industry. The technical strength and production process of products need to be improved. The scale of failure in domestic MEMS industry is relatively small, but there is a lot of room for development in terms of market scale. Facing the huge domestic consumer electronics market, it is also a shortcut for fabless to produce and sell by itself to meet the demand of some domestic low-end markets.

1. Regional layout of domestic sensor Enterprises

China’s MEMS design enterprises are mainly concentrated in East China, accounting for about 55% of the total number of enterprises in China

Shanghai: Shen Di, Si Rui, Li Heng, Xin Min, Wei Lian, Ming Dong, Wen Xiang, Tian Ying, Ju Ge

Suzhou: Mingfu, Minxin, Shuangqiao, Duowei, nengstar, Wenhao, San senor, Ximei
