Electronics industry urgently needs a new micro-electromechanical systems (MEMS) sensor and to drive things (IoT) development. According to industry analysts said that if the expected use of things driving the growth of the next round of the electronics industry, in large part have to rely on MEMS and sensor technology in order to make all the smart objects interact with the real world. But to achieve new MEMS design to production, it may take a very long time and the high cost in order to meet the market’s expectations of things – unless the electronics industry can find their way to accelerate the development of MEMS.
New applications using existing MEMS components are 12% annual growth rate driven market progress MEMS. However, Jean-Christophe Eloy Yole Dveloppement executive and president, said, unless the industry can find how to successfully convert the mechanical element silicon approach, or to speed up the degree of difficulty with the revolutionary new production might slow down future MEMS market growth .
MEMS completely absent innovative products for over a decade
Through the application of more sophisticated and more widespread adoption of MEMS components, is expected to make this smaller size, higher performance and more cost-progressive element of innovation, continue to stimulate the sensor and the implemented system towards strong growing up. Last year in the field of MEMS to achieve the most rapid growth be Avago (Avago Technologies) and Qorvo (formerly Triquint), this is because of the wide spread of bulk acoustic LTE multi-mode handsets to be used (BAW) filters pose a very big demand. Similarly, strong demand for more applications MEMS microphone and inertial sensors for help drive more sensors suppliers into 2-3 million in annual revenue range ranks.
“It’s really important, because there are a number of companies have the potential to develop into a $ 1 billion company,” Eloy said.
However, only new applications using existing components to maintain double-digit growth of the type of $ 11 billion business, in time may not be long. “One challenge is completely innovative product recently or 2003 Knowles (Knowles) developed MEMS microphone.” Eloy said, “Since then, all but the degree of integration, better packaging, etc. bring progressive Innovation While these are very important innovation, but not a breakthrough new products. We are still waiting MEMS switches, speakers and other products autofocus and full transition to mass production stage. ”
The semiconductor industry has found ways to expand cooperation in the field of pre-competitive research, and have a well-developed commercial infrastructure to support continued growth, he said. “MEMS industry needs some changes occur, in order to simplify and speed up the design process, and put into production as soon as possible.”

“As everywhere need sensors to achieve things, situational awareness, especially for the emerging demand for new biochemical and biomedical sensors, I think the development of MEMS industry really only just begun,” President of the Silicon Valley investment industry Band of Angels SIG Board Kurt Petersen expressed. “Prices will continue to decline, but the development of a new type of sensing mechanism will significantly improve the accuracy,” for the development of a piezoelectric microphone, ultrasonic gesture recognition as well as new technology brings tremendous inertia potential impact – a higher 10 significantly improved the accuracy of fold navigation information.
Peterson believes truly useful wearable device has not yet been developed, but expressed optimism about its future development. The most promising are now being developed in a new class of biological sensors, such as startups Profusa implantable glucose sensor, an external optical device to read, which uses an adjustable sensor platform, in the human body detection chemical drugs.
In addition to better biochemical and biomedical sensors, energy harvesting is another opportunity. “Energy harvester will become increasingly important, because things will provide a huge market,” he said.
MEMS promote the growth of new platforms
In order to claim the fastest time to market and cost-listed, these new elements into volume production of MEMS, semiconductor industry to promote the development of new methods.
“When we turn to the past customers usually require their own unique process, but now there are more and more customers asked us to use standard platforms as possible, with only minor modifications to,” Teledyne Dalsa company’s executive vice president of MEMS foundries Claude Jean and general manager. “A product manufacturing process uses a traditional approach has not been completely eliminated, but more and more customers tend to use mature platform to develop products,” he adds.
Dalsa company is inertial sensors, micro-bolometer, optical MEMS and piezoelectric elements provide a wider range of different platforms, and extend as far as possible their own design and testing support services.
The new platform technology from R & D laboratories. Electronics and Informatics Department of the French Atomic Energy Technology Laboratory (CEA-Leti) aims to cooperate with the foundry, which was put into production piezoresistive MEMS platform to provide to more customers. This technique of moving the material using the “10? m thick layer, and the “500nm thin layer to the edge of the piezoresistive element, then change the resistance through compression or tension to detect its movement.
“The technology is tightly integrated multiple sensor provides alternative methods, or CMOS imaging systems can help manufacturers, and the lack of its own technology in the new company to develop products quickly.” CEA-Leti strategic partners in North America Vice Hughes Metras president and stated, CEA-Leti has been made with the authorization of the industry’s first Tronics quickly its six degrees of freedom inertial sensor market a.
Today, these basic technologies mature also means MEMS market began to seek advantage from a number of cooperation based on mutual interest, in particular with regard to some of the equipment requirements or testing operations. Currently in measuring performance inertial sensors have not been widely accepted standards, does not define the means of future demand for device manufacturers like ITRS roadmap, Teledyne Dalsa’s Jean said.
“At present there is a huge gap between the cost of the MEMS market requirements and available advanced CMOS devices.” He believes that “However, compared to the development of advanced CMOS process, it also requires simpler and more cost-effective TSV manufacturing process and other technical support. ”
Teledyne Dalsa is working with Alchimer wet after the development of low-cost copper processing drilling (Via-Last) MEMS TSV approach. Teledyne DALSA’s Via-Last technology uses copper drilling, and using low-temperature electrochemical process Alchimer formed x100 microns deep perfect perforations filled with five microns in diameter, and the use of copper redistribution layer and Ni / Au UBM is connected to the outside. However, the process is currently available only 200mm wafers, therefore, “we need to start closer cooperation between the MEMS manufacturers and equipment and materials suppliers to develop more cost-effective way to promote innovation progress.” He said.
