SEMI-MEMS & Sensors Industry Group (MSIG) welcomed a global group of industry executives to its 14th annual(MSEC), October 29-30, 2018 in Napa, Calif. MEMS and sensors represent a robust sector of the electronic industry. Analyst firm Yole Développement expects the global market for MEMS and sensors to double in the next five years, reaching $100B by 2023, spurred by growth of autonomous mobility products such as Internet of Things (IoT) devices, autonomous cars, fitness and healthcare wearables, and agricultural sensors.
“From drones that navigate any terrain in all lighting conditions, robo-taxis that ‘smell’ cigarette smoke, and sensors that monitor animal welfare and food safety, MSEC speakers shared inventive use cases representing new opportunities for MEMS and sensors suppliers,” said Carmelo Sansone, director,. “Our keynote speakers spurred attendees to collaborate for the greater good. MITRE Corp. cybersecurity expert Cynthia Wright exhorted attendees to proactively address cybersecurity. DARPA Microsystems Technology Office (MTO) program manager Ron Polcawich invited participation in a rapid innovation and production concept that could dramatically speed design cycles for new MEMS. They exemplify the cross-pollination among commercial industry, government and academia that will continue to advance MEMS and sensors.”
Getting serious about cybersecurity
MITRE cybersecurity expert Cynthia Wright opened MSEC 2018 with a keynote on cybersecurity, alerting attendees to a topic that few in the industry have explored in-depth — but to which they need to pay attention.
“Billions of connected mobile devices democratize knowledge, diversity and boost economies, and accelerate innovation by connecting humans to one another and to our environments,” said Wright. “At the same time, they easily create huge networks that carry operationally and personally sensitive data.”
Because MEMS and sensors are deeply embedded into this vast array of connected devices, industry needs to get involved now or risk potentially grave consequences, claimed Wright. “From the destruction of critical infrastructure, cyberattacks on life-critical medical devices such as insulin pumps and heart monitors, and intrusions on autonomous vehicle safety systems, MEMS and sensors suppliers have a responsibility to help improve cybersecurity of connected devices,” she added.
Allaying the potential fears of a roomful of suppliers envisioning complete redesigns of their products, Wright said that not every device requires the same level of security, and suppliers can make a difference with even “minor tweaks.”
Wright suggested encryption at the edge and process authentication. She also gave MSEC attendees a list of design precepts:
- Build it in. Don’t bolt it on — Design your device with security in mind instead of retrofitting it after-the-fact to realize the most elegant design.
- Beware of shadow IT — You can’t protect what you don’t know about. Consider physical asset security; software/sensor-guided decision-making; personal or operational data collection; and key process control.
- Realize your points of vulnerability — because MEMS and sensors are susceptible to spoofing.
- Learn from cyberattacks of the past — even if they have not been tied directly to MEMS/sensors.
- Understand IoT software — Realizing that IoT software acts on what the hardware tells it, pay attention to altered sensor data that can lead to altered system performance.
When asked about the role of US government regulation on the security of connected devices, Wright acknowledged that Europe has more restrictive cybersecurity guidelines than the US.
“At the same time, it does not make sense to have two different approaches to cybersecurity of devices. US suppliers who implement more security measures can sell to both markets and to other parts of the world.”
If she could leave MSEC attendees with a closing thought, it might be that companies “don’t need to put a firewall on a toaster.”
“Not every chip has to be secure-foundry secure, but it would be nice if even 10% could hit that mark,” added Wright.
Rapid Innovation through Collaboration
IC designers typically enjoy three to four design cycles in a calendar year, leading to swift advancement of electronics over subsequent years.
Designers in the MEMS community, however, generally have access to one design cycle or less per year, and typical time-to-market is four years for a new product. That slow fabrication pace has hindered deployment of innovative MEMS designs — and it’s something that MSEC closing keynote speaker, Ron Polcawich, program manager, DARPA MTO, would like to change.
Polcawich’s vision of government collaboration with industry and academia spawned the investigational Rapid Innovation through Production MEMS (RIPM) Workshop, which Polcawich and his team held in May 2018. During his keynote, Polcawich shared lessons learned from the workshop while inviting MSEC attendees to get involved.
Before RIPM can become a program, Polcawich knows it will require definition. What would a program concept look like? What is the best way to articulate the potential benefits to the MEMS community, and what additional inputs would be needed?
“This is a daunting challenge from a program planning perspective,” said Polcawich. “In developing RIPM, we realized that we needed representatives from the entire MEMS ecosystem – integrated device manufacturers, or IDMs, equipment suppliers, foundries, and materials’ providers — to literally come to the table to tackle a common goal. Given the potential for the MEMS industry at large to benefit from rapid innovation and production, we hoped that competitors would realize that leveraging established MEMS processes could deliver significant benefits over the historically entrenched approach: one product, one process.”
Polcawich believes that MEMS suppliers might relinquish the one product, one process paradigm if they knew that their IP were secure.
“While technical challenges to realizing RIPM abound, we knew that we could tap the MEMS industry’s vast knowledge base to address them,” he said. “IP protection is an equally complex issue, and one that may bear a range of approaches. One model could ensure that each IDM owns their IP while the foundry owns the process technology, which it licenses to other companies through process development kits. In addition to speeding innovation, it also provides new revenue sources for the industry.”
Polcawich sees RIPM as a win-win for both commercial industry and for the DoD. Speeding design-to-deployment of new MEMS devices could open new and larger markets to MEMS suppliers. It could also support greater product-line diversification and new revenue streams for foundries and other ecosystem members. The DoD could tap new MEMS devices for strategically important applications like tactical radios, unmanned aircraft systems such as drones, and image autofocus for cameras.
