According to speakers who will attend the US Semiconductor West Conference in San Francisco, California from July 14th to 16th, the industry is in urgent need of new MEMS to promote the development of sensors and the Internet of Things.
If the Internet of Things (IoT) is driving the next round of electronics growth, it will rely heavily on MEMS and sensor technology, because only these MEMS and sensor technologies will allow all of these smart objects to interact with the real world. But from MEMS design to mass production can take a long time, and it will cost a high price to meet the requirements of the IoT market, unless the industry can find a way to accelerate MEMS development.
New applications for existing MEMS devices are driving the MEMS market at a healthy 12% annual growth rate, but the difficulty of mass production of breakthrough new products may slow down growth unless the market finds out how to smooth out mechanical devices and convert them to silicon. The approach, said Jean-Christophe Eloy, CEO and President of YoleDéveloppement. He will deliver a speech on the future of MEMS at the 2015 US Semiconductor West Conference in San Francisco on July 14.
MEMS completely innovative products have been absent for more than ten years
By enabling more applications to adopt mature MEMS devices more widely, this smaller, higher performance, lower cost progressive device innovation has been spurring the robust growth of sensors and systems implemented with them. The fastest MEMS growth last year occurred in Avago and Qorvo (formerly Triquint), as the widespread adoption of LTE placed great demands on BAW filters for multimode handsets. Similarly, the increased demand for MEMS microphones and inertial sensors from more applications is driving new sensor suppliers to the 200-300 million annual revenue range.
“This is really important because there are now a number of companies with the potential to grow into a $1 billion company,†Eloy pointed out.
However, new applications that use existing types of devices can maintain a double-digit growth in the 11 billion business may be very limited. “The challenge is that the most recent and completely innovative product is the Knowles microphone of 2003.†Eloy said, “Since then, there have been only incremental innovations in terms of integration, better packaging, etc. Although these are also very important innovations. But not a breakthrough new product. We are still waiting for the full transition of MEMS switches, autofocus and speakers to mass production."
MEMS new platform begins to appear
The IC industry has found ways to collaborate in pre-competitive research areas and has a developed commercial support infrastructure to support continued growth, he said. “The MEMS industry needs to make some changes in order to simplify and speed up the design process and put it into mass production as soon as possible.â€
The time-to-market and low-cost requirements to bring these new devices into volume production and meet market requirements are driving the industry to develop new approaches.
“In the past, people came to want us to implement their own unique processes, but now more and more people are asking us to use standard platforms as much as possible, with only a few modifications.†It will also be presented at the Semiconductor West Conference. Claude Jean, executive vice president and general manager of Teledyne Dalsa's MEMS foundry, said. “A product, the traditional approach of a process has not been completely eliminated, but people are increasingly trying to develop products with mature platforms,†he added.
Dalsa is offering a wider range of different platforms for inertial sensors, microbolometers, optical MEMS and piezoelectric devices, and expanding its design and test support business as much as possible.
The new platform technology also comes from the R&D lab. CEA-LeTI wants to work with the foundry to put the company's piezoresistive M&NEMS platform into production for more users. This technique uses a thick layer ("10?m") to move the material, a very thin layer ("500 nm") for the piezoresistive meter at its edge, and then changes its resistance by compressing or straining it to detect its motion.
"This technology provides an alternative approach to very tightly integrating multiple sensors, helping new companies like systems or CMOS manufacturers without their own technology to quickly develop products." Vice President, North American Strategic Partners, Hughes Metras, another expert who spoke at the Semiconductor West Conference, pointed out that he also mentioned the speed of the first licensor, Tronics, to bring its six-degree-of-freedom inertial sensor to market.
The maturity of these basic technologies now also means that the MEMS market is beginning to seek benefits from some of the common interests, such as equipment requirements or test operations. There are currently no widely accepted standards for measuring the performance of inertial sensors, and there is no such thing as an ITRS roadmap that specifies future requirements for equipment manufacturers, Dalsa's Jean noted.
"There is a huge gap between the cost of the MEMS market and the available advanced CMOS devices," he said. "However, this requires technical support such as a simpler, lower-cost TSV process than the process developed for advanced CMOS. ""
Dalsa is working with Alchimer to develop a low-cost wet process copper via-last MEMS TSV method. “We need closer collaboration between MEMS manufacturers and equipment and materials suppliers to develop a lower cost method to move everyone forward,†he said.
At the Semiconductor West Conference, the above speakers will discuss "What is the next big thing in the MEMS field?" Other TechXpot agendas at the conference will address the impact of the Internet of Things on the semiconductor industry, the current state of non-volatile memory, and biomedical and automotive applications.
In addition, SEMI (formerly known as the International Trade Association for Semiconductor Equipment and Materials) and the MEMS industry organization will invite interested parties to participate in a participatory studio established at the Semiconductor West Conference on July 15 to study potential cooperative intentions. In order to help the field move forward. “There are a number of interesting business reasons that require standards for MEMS development,†said Alissa Fitzgerald of AM Fitzgerald & Associates, who will deliver a keynote speech at the studio.
Emergency LED drivers are designed specifically for light fixtures . These emergency backup drivers regulate the power supplied to the LED fixture the same way normal drivers do , but they operate off of a battery instead of line voltage . Because they operate off a battery the light output isn't as bright as the fixture normally would produce , but it will be just enough in an emergency situations . Most of our emergency LED drivers have a maximum emergency operation time of 120 minutes .
