ASN had a chance to talk to François Brunier of Soitec, who’s leading this important project.
Advanced Substrate News (ASN): Can you tell us briefly about OCEAN12?
Francois Brunier (FB): OCEAN12 stands for Opportunity to Carry European Autonomous driviNg further with FD-SOI technology up to the 12nm node.
OCEAN12 deals with “Ultra-low power computing solutions for automotive and aeronautics using all the range of FDSOI technologies”. This project with a budget of 103M€ brings together 27 partners from 7 different countries. The project received the ECSEL JU* label under the 2017 call. ECSEL is an EU-driven public-private partnership enabling the co-financing of innovation in electronic components and systems both by Member States and the European Union.
ASN: Why is this project needed?
FB: As of today a car has around 500 million transistors. These electronic components represent already an important vector of valorization and differentiation for the automotive industry and for the consumer. The increased autonomy of the vehicles will require a very strong build-up of computational capacities. 50 to 100 times more transistors could be required for a level 5 (fully autonomous car). Following this trend an autonomous car will require power consumption equivalent to 50 to 100 computers running continuously (without taking into account the car propulsion).
The power consumption of these components becomes a key element in the choice of technologies. We believe that our technologies on SOI present the best assets to meet this challenge.
The FD-SOI substrates, technologies and designs developed in OCEAN12 offer a palate of different solutions to this challenge: increased performance for data processing (including Artificial Intelligence); much higher energetic efficiency; and smaller form factors to fit in embedded systems like autonomous cars with higher integration and reliability, and enabling safe connectivity.
The OCEAN12 project will demonstrate that SOI technologies are able to meet these challenges through relevant demonstrators in the targeted fields.
ASN: What are the project goals?
FB: OCEAN12 will bring concrete solutions to the main challenges of smart connectivity and low power consumption in the automotive industry.
As such, OCEAN12 will build awareness around the key enabling technologies in substrate development, transistor behavior, and the design and fabrication of integrated circuits up to the system and end-user application levels. We will show that the technology is advantageous for automotive and aerospace applications, which are strategic sectors for Europe. Having the whole supply chain in Europe means having trusted and secured components made in Europe.
The OCEAN12 project goals stand on three pillars:
First: Confirming the technology foundation. Ocean12 puts the FD-SOI substrate and device developers in direct contact with the full value chain of suppliers and end users. This gives the entire ecosystem visibility into current and future needs, and ensures that substrate and device solutions are both technically feasible and correctly aligned with actual system requirements.
Second: Creating concrete, innovative demonstrators in automotive (Audi, Bosch) and aeronautics (Airbus, Thales). These demonstrators are a first step in defining the context and environment to prove the advantages of these technologies in real application cases, showing they are useful and as such prefigure a final system and a potential future product roadmap. Demonstrators should be as close as possible to the final application.
Third: Broadening the design ecosystem, with the big companies, the small- and medium-sized companies (SMEs) and the research organizations (universities, RTOs). We have a critical mass of 16 design ecosystem partners focusing their efforts on FD-SOI. The project leverages that dynamic FD-SOI design ecosystem for IC product migration to FD-SOI and the creation of new IP. Inventing the future components in Europe is also key.
ASN: Can you tell us more about the demonstrators? When will we see them?
FB: There are four demonstrators. All these demonstrators will be delivered by the end of the project in 2021:
Always-on wake-up systems (Audi, Bosch, Leti). With such a system we can imagine an application to monitor our car when it is parked in a parking lot for a long time. The sensors would remain aware of everything that goes on around the car. Based on sensor observations, the car can make decisions on further actions to take. This can be used in many future car applications like intrusion detection or vehicle access systems. But you will not have to worry about battery drain: even though all the sensors are always on, they go right back into a very low-power sleep mode thanks to FD-SOI technology.
mm-Wave integrated radar SOCs (Bosch and Audi), which will benefit from all the innovations of FD-SOI thanks to its low consumption properties, but also the optimization of the sensors. The performance gain is made over the entire system with adaptations between analog and logic.
High-performance video processor for aeronautics. (Airbus, Thales, Kalray). Kalray, a French SME working on Massively Parallel Processor Arrays (MPPA) aims to demonstrate an ultra-low power, low-cost, high-performance neural processor on FD-SOI technology. This demonstrator would be key for Airbus and drones with high-performance, low-power cameras. Airbus and Audi have partnered on air and ground mobility services.
Microcontroller plug-and-play board. This demonstrator lead by ST will allow for the development of new solutions in the domain of GNSS/GPS.
ASN: Can you tell us more about the partners?
FB: The OCEAN12 consortium of 27 partners involves 8 large groups, 9 SMEs and 10 universities/RTOs. These partners come from 7 different European countries.
The eight large groups include: Soitec, the world’s leading provider of FD-SOI substrates; EVG, a leading global equipment supplier; GlobalFoundries and STMicroelectronics, the two major European FD-SOI foundries; and Bosch, as a Tier 1 automotive supplier. At the top of the value chain, high-end European automotive manufacturer Audi, the avionics industrial giant Airbus, and Thales for security issues, will develop product demonstrations.
Ten highest-level research institutes support the industrial consortium. They include CEA-Leti (FR), Fraunhofer(GE), IMS (FR), INP Grenoble (FR), TU Dresden (GE), U. Paderborn (GE), Bundeswehr U. Munich (GE), Eberhard Karls U. Tübingen (GE), Instituto de Telecomunicações (PT), and Warsaw UT (PL). They increase the competitiveness through technological innovation and transfer of technical know-how while gaining new expertise working with global leaders.
In addition, OCEAN 12 has a very strong SME consortium covering the supply chain in the fields of new equipment, IP, system integration and fabless companies. They include: IBS, UnitySC (HSEB), MunEDA, Kalray, AED Engineering, ISD, EVOTEL, M3 Systems and Design&Reuse.
All these partners have longstanding experience of cooperation in various national and international frameworks and are specialists in their fields of activity. Their contributions are essential for the success of the project.
ASN: What is the timetable?
FB: The project started on April 1st 2018. The kick off with all the partners was held at Soitec on 29 September 2018. It was a great success. The project runs through December 2021, by which point everything has to be demonstrated.
ASN: Can you clarify the funding structure?
FB: The budget is about €103.6M. If the project succeeds, we get European Commission funding. In that case, just over 20% of the eligible cost – about €23M – is subsidized at the European level. The seven countries with companies or organizations participating in the project will then roughly match the European subsidies, contributing about €27M.
These ECSEL-type public-private projects are a tried and true model in Europe, maximizing synergy across ecosystems.
To conclude, in the name of the consortium I’d like to thank the ECSEL JU, the European Commission and our National Funding Agencies from France (DGE), Germany, Portugal, Greece, Spain, Austria and Poland. Such a project would not exist without them.

FD-SOI was a very important topic during the recent Mount Qingcheng China IC Ecosystem Forum. To situate things, Mount Qingcheng, with its lush hills and waterways, is located just outside of Chengdu. That of course is where GlobalFoundries is building its new fab, which will be the first in China to run FD-SOI. Chengdu is also a key city in China’s automotive electronics landscape.
The theme of the forum was Building a Smart Automotive Electronics Industry Chain. Over 260 decision-makers from government, academia and industry attended – and the SOI Consortium had a significant presence. The event was chaired by Wayne Dai, CEO/Founder of consortium member VeriSilicon, and tireless champion of the the FD-SOI ecosystem in China and worldwide. Morning keynotes were given by: Carlos Mazure, Soitec CTO and SOI Consortium Executive Co-Director; Mark Granger, GF’s VP of Automotive Product Line Management; and Tony King-Smith, Executive Advisor at AImotive, a GF 22FDX customer.
BTW, transcripts of all the talks are available through Gasgoo, China’s largest automotive B2B marketplace. You can click here to access them. (They’re in Chinese – but you can open them in the language of your choice using the major translation websites.)
Fan Yi, Deputy Mayor of Chengdu, spoke extensively of FD-SOI in his keynote on the importance of rapidly developing smart cars.
He heralded the “spectacular” new GlobalFoundries fab there. Following a meeting with the company’s top brass the day before, he affirmed GF’s confidence in their investment. There is a solid roadmap for FD-SOI, he noted, and efforts are underway to accelerate the move into production and expand education and training. He cited the benefits of FD-SOI for the entire supply chain, from design through package and test, raising the level of the entire IC industry to new heights. The government, he said, attaches great importance to this enterprise. Their thinking regarding intelligent transport in China is integrated with the overall approach to smart cities.
In his opening remarks, Wayne Dai emphasized the need for China to seize the advantage in the next round of development opportunities in the automotive electronics industry. This year’s Qingcheng forum, he noted, brought together key representatives from across the supply chain, from of the highest to the deepest reaches of the smart car electronics industry, and across markets, technologies, solutions, industrial ecosystem, standards and regulations.
In his talk on how FD-SOI is boosting the accelerated development of automotive electronics, Carlos Mazure presented the SOI Industry Consortium. He noted that the Consortium promotes mutual understanding and development across the ecosystem. SOI is already present throughout automotive applications, he noted. There are currently about 100mm2 of SOI per car, in such diverse areas power systems, transmissions, entertainment, in-vehicle networking and more. SOI will experience especially high growth in electrification, information/entertainment, networking, 5G, AI/edge computing and ADAS. He then went on to give some history and an extensive overview of the major trends and highlights we’ve seen over recent years. He finished by giving examples of convergence across the supply chain with IC manufacturers working with automakers to lower power, increase processor performance and advance 5G.
GF’s Mark Granger addressed the rapid development of automotive electronics. In certain areas, he said, he sees growth rates of over 20%. They are working on building the Chengdu ecosystem, especially for design, and in cooperation with the rest of the supply chain. Furthermore, he reminded the audience, when you talk about cars, travel implies that you also talk about IoT as well as things like infotainment and integrated radar ICs. In addition to cost and power efficiencies, the AEC-Q100 standard for IC reliability in automotive applications is also pushing designers to turn to FD-SOI. In the GF meeting with Chengdu government officials (referenced above in deputy mayor Fan Yi’s talk), he too confirmed their support of FD-SOI as a key technology for China. GF is currently cooperating with about 75 automotive partners, he said, and the company is looking to increase cooperation with partners in the Chengdu region.
Tony King-Smith talked about the 22FDX test chip AImotive is doing with Verisilicon and GF. In case you missed it, in June 2017 AImotive announced its AI-optimized hardware IP was available to global chip manufacturers for license. AiWare is built from the ground up for running neural networks, and the company says it is up to 20 times more power efficient than other leading AI acceleration hardware solutions on the market. In the same announcement, they revealed that VeriSilicon would be the first to integrate aiWare into a chip design,and that aiWare-based test chips would be fabricated on GF’s 22FDX. The chip is expected to debut this year.
While the afternoon agenda was not specific to FD-SOI, it did focus on the “smart cockpit” and “intelligent driving”, with talks by nine leading players in China’s automotive IC and investment communities.

GF’s 22FDX® (22nm FD-SOI) offering is on an automotive roll. The technology platform has been certified for several key automotive standards, and GF has announced an exciting new ADAS customer in Arbe Robotics.
In addition to sharing info from various press releases and blogs, ASN also had a chance to catch up with Mark Granger, GF’s VP for automotive, who provided some great insights. Read on!
When it comes to compliance, automotive industry standards are excruciatingly rigorous. Every part that goes into a car must adhere to the relevant standards: chips are no exception. One such standard is the AEC – Q100, a “Failure Mechanism Based Stress Test Qualification For Integrated Circuits”. The AEC – aka the Automotive Electronics Council – handles those testing standards and certification. Grade 2 means a technology is certified for the -40°C to +105°C ambient operating temperature range. To achieve Grade 2 certification, devices have to successfully withstand reliability stress tests for an extended period of time over the specified temperature range.
GF recently announced that 22FDX has been AEC Q100 Grade 2 certified (press release here). However Granger adds that for their customers, they’ve added additional headroom that takes them to 125°C. They’re now working on Grade 1 certification, he says, which means the devices are certified to handle junction temperatures up to 125°C (and there again, GF has added additional headroom that takes them to 150°C). That should be done by the end of 2018. The ability you get with FD-SOI to tune the transistors using body biasing is really beneficial here, he says.
For GF, the 22FDX qualifications exemplifies their commitment to providing high-performance, high-quality technology solutions for the automotive industry. The automotive industry is driven by a “zero excursions – zero defects” mindset, says Granger, and that drives the foundry, too.
SOI has been used for decades across industries where heat and electromagnetic radiation are challenges, bringing soft error rates (SER) down by orders of magnitude, notes Granger. (SOI, btw, essentially eliminates what are known as Single Event Upsets (SEU) caused by latch-up, which in turn brings down SER.) That in turn, ties into the FIT (failure in time) rate – and that’s part of the ISO 26262 “Road vehicles – Functional safety” standard – where 22FDX is also certified.
As a part of GF’s AutoPro™ platform, 22FDX allows customers to easily migrate their automotive microcontrollers and ASSPs to a more advanced technology, while leveraging the significant area, performance and energy efficiency benefits over competing technologies. Moreover, the optimized platform offers high performance RF and mmWave capabilities for automotive radar applications and supports implementation of logic, Flash, non-volatile memory (NVM) in MCUs and high voltage devices to meet the unique requirements of in-vehicle ICs.
GF’s Fab 1 in Dresden, Germany (which is where they do 22FDX) also has achieved ISO-9001/IATF-16949 certification, which demonstrates that it is capable of meeting the stringent and evolving needs of the automotive industry. (IATF is the International Automotive Task Force. 16949 is a Quality Management System (QMS) certification specifically for the automotive sector.)
Granger wrote a really informative blog on the GF website – you can read it here. It includes this graphic, indicating where in the car 22FDX-based parts are expected to go.
GF recently announced that Arbe Robotics selected 22FDX® as the process technology for its groundbreaking patented imaging radar. Arbe aims to achieve fully automated system capabilities and enable safer driving experiences for autonomous vehicles (read the press release here).
As the first company to demonstrate ultra-high-resolution at a wide field of view, Arbe Robotics’ radar technology can detect pedestrians and obstacles at a range of 300 meters, in any weather and lighting conditions. The processor creates a full 3D shape of the objects and their velocity, and classifies targets using their radar signature.
As Granger noted in his blog, “Radar is one of several sensor types used to detect objects near a vehicle, to enable features like adaptive cruise control. Lidar is another. It uses pulsed lasers to determine distance from an object by measuring the time it takes for the light to reflect back. However, lidar is currently expensive and is affected by weather conditions. Radar is less expensive, and higher-resolution radars promise to compete well with lidar in automotive applications, thereby enabling lower-priced vehicles to enjoy greater ADAS capabilities. 22FDX-based radar sensors can provide higher resolutions and less latency than current radar sensors at a very low total system cost.”
While they may be complementary at first, there is a battle brewing between high-resolution radar and lidar, Granger told ASN. Putting their solution on 22FDX enables Arbe to achieve a 77 GHz mmWave radar and compete cost-effectively with lidar. “They wanted the best,” says Granger. 22FDX can achieve the requisite Ft and Fmax figures of merit. And with transistor stacking, they can also integrate the power amplifier (PA) on a single device. With the low inherent capacitance of the PA in 22FDX, you can get the high power output you need for mmWave but with low power consumption.
GF blogger Dave Lammers has also written a great piece about the Arbe solution (you should read it: here’s the link). “The company said its advanced technology allows the detection of small targets, such as a human or a bike even if they are somewhat masked by a large object such as a truck,” he writes. “The imaging radar can determine whether objects are moving, and in what direction, and alert the car in real-time about a risk.
“While other car sensors can fail when it is raining, if there’s fog, and due to blinding lights such as a sudden reflection, Arbe’s radar is completely oblivious to all those factors. The custom designed radar processor creates a full real-time 4D image of the environment, and classifies targets using their radar signature.”
Avi Bauer, Arbe’s VP of R&D, is now clearly an SOI fan. Lammers quotes him as saying, “With SOI the design is more straightforward, and (voltage) biasing allows you to do things that cannot be done in standard CMOS. For the transmit and receive modules, SOI’s higher resistivity substrate benefits the passive components – inductors and capacitors – and allows good isolation. High Q passives are important. At 22nm, SOI allows better performance overall.”
Clearly good things are coming down the road for FD-SOI!
They’ve got initial silicon of Dream Chips’ ADAS SoC fabbed in GlobalFoundries’ 22FDX (FD-SOI) technology, and it’s got record power efficiency (read the full press release here). The chip offers high performance image acquisition and processing capabilities and supports AI / Neural Network (NN) vision operation with a total of 1 TOPS at 500 MHz on 4 parallel engines. With all functions including quad-core Arm® Cortex®-A53, Tensilica DSPs, and INVECAS’ LPDDR4-Interfaces activated, the SoC shows single digit power dissipation without the need for forced cooling, which is of significant importance for embedding in automotive environments.
Targeting automotive computer vision applications, the SoC was created in close cooperation with Arm, ArterisIP, Cadence, GF, and INVECAS as part of the European Commission’s ENIAC THINGS2DO reference development platform, where about 40 partners in Europe cooperated to propel the FDSOI-Design Ecosystem.
Of particular importance is the new and reduced power footprint of this SoC in 22FDX-technology from GF. AI/NN-operation for image recognition is available today, but most of the solutions need active cooling. Implementation of Dream Chip Technologies’ SoC on GF’s 22FDX platform demonstrated single digit Watt and cooling targets for designers managing power dissipation. If needed, the SoC bears the potential to increase the performance even further up to 2 TOPS at 1.0 GHz by applying GLOBALFOUNDRIES’s forward body-bias capabilities and other optimization techniques.
The jointly developed ADAS SoC platform from Dream Chip Technologies is available now. Part of GF’s FDXcelerator™ Partner Program, Dream Chip is the largest independent German Design Service company specialized in the development of large ASICs, FPGAs, embedded software and systems with a strong application focus on automotive vision systems (ADAS).
