We created an Innovation Office in 2020 to sustain, stimulate, facilitate, and coordinate the process of continuous innovation within ST, in line with our strategic objectives. Innovation is a collaborative task requiring the best of collective intelligence to succeed. To enhance our ability to assimilate and generate innovation, we are improving the exploration and transformation phase of the innovation process, increasing both internal and external scouting and cooperation capabilities.”

Leading-edge technology

ST is currently well positioned in disruptive technologies and applications. We are focused on bringing to market disruptions that have been enabled by our past investments. We leverage our process technology to create opportunities to penetrate new markets, form new partnerships or acquire new competencies.

Process technology

Thanks to our wide portfolio of patents and strong pipeline of innovation, today we are one of the few semiconductor companies mastering a very broad range of chip fabrication technologies.

Acquired majority stake in Exagan

a French GaN epitaxy innovator

Among these technologies, Gallium Nitride (GaN) technology is part of our strategy to invest in wide bandgap technologies, complementary to Silicon Carbide for power devices. In 2020, we acquired a majority stake in the French GaN innovator, Exagan, whose expertise in epitaxy, product development and application know-how will broaden and accelerate our power GaN roadmap and strengthen our business for automotive, industrial and consumer applications. We also started the epitaxy step of the 200mm GaN line in our Tours site (France).

During the year, a technology breakthrough, combining embedded phase change memory (e-PCM) with the advantages of 28nm FD-SOI technology and advanced packaging, enabled us to develop a new automotive microcontroller product line, called Stellar, in partnership with our customer, Bosch. It provides advanced connectivity and security features to support the transition to service-oriented automotive systems.

Application technology


RF and wireless

connectivity companies

In 2020, to complement and strengthen our STM32 microcontroller offer, we acquired companies and assets focused on radio frequency (RF) and wireless connectivity: Riot Micro for its expertise in low-power cellular IoT; BeSpoon, which specializes in ultra-wide-band connectivity; and SOMOS semiconductor, which specializes in silicon-based power amplifiers and in RF front-end modules (FEM). Acquiring these companies and integrating them into our business will enable ST to provide all IoT connectivity system-on-chip solutions and accelerate our time to market for our STM32 portfolio (see Focus).

Strengthening our RF and wireless connectivity capability

Today, ST offers reference designs to serve the global embedded connectivity market. To enhance the range of connectivity standards we offer, in 2020 we acquired Riot Micro, BeSpoon and SOMOS  semiconductor.

Riot Micro designs cellular IoT solutions, applying proven techniques from Bluetooth Low Energy to create narrowband IoT solutions optimizing system cost and power. The integration of cellular communication capabilities into the STM32 microcontroller portfolio will strengthen our offer for customers developing applications such as asset tracking, metering, and fleet management services for the industrial market.

BeSpoon technology enables secure real-time indoor location with centimeter accuracy even under adverse conditions. The integration of this secure positioning technology in the STM32 portfolio will enable developers of IoT, automotive and mobile communication applications to provide services such as secure access, and precise indoor and outdoor mapping.

With the SOMOS acquisition, we have reinforced our specialist staff, IP and roadmaps of front-end modules for the IoT and 5G markets.

In the increasingly important field of artificial intelligence, we capitalize on synergies between our microcontrollers, sensors, and automotive application groups. Leveraging this expertise, in 2020 we demonstrated a prototype IoT sensor that enables new building management services and efficiency gains by understanding building occupancy levels and usage for our customer, Schneider Electric.

Innovation ecosystem

The innovation process begins with an exploration phase that enlarges our funnel of opportunities, combining internal know-how with external sources of innovation and partners. I 102-12 I

External scouting for technology

Recognizing the importance of partnerships in the innovation process, we build strategic alliances, engage in bilateral research cooperation, and participate in standardization groups. Overall, we were involved in 143 active R&D partnerships in 2020.


active R&D partnerships

Our ST Partner Program provides our partners with the ecosystem needed to help them reduce development effort and accelerate time to market. The program continues to grow, reaching 292 members in 2020 (see I 103-3 I

We are also members of many industry associations. In 2020, we joined Silicon Catalyst, an incubator focused on accelerating solutions in silicon, to expand our network of contacts investigating innovative IP and to be involved in discussions around industry standards.

We also launched a ‘Lab-in-Fab’ in collaboration with the Institute of Microelectronics at Singapore’s Agency for Science, Technology and Research (A*STAR) and ULVAC, a leading Japanese vendor of manufacturing tools. This ‘Lab-in-Fab’ R&D line brings together three partners with leading-edge and complementary competencies in piezo materials, piezo MEMS technologies, and wafer-fab tools. The objective is to boost innovation and accelerate development of new materials, process technologies, and ultimately, products.

Working with startups

We are involved in a number of initiatives to support electronics-related startups in various locations relevant to our business. These initiatives are tailored to address the typical challenges faced by startups and to drive mutually beneficial collaboration.

In the early stages, we provide support to external innovation and co-working spaces called Proof of Concept (PoC) centers, spread across countries where we operate. The aim is to help innovative small businesses and startups speed up their proof-of-concept phase. Including the new centers opened in 2020, such as ComoNext in Italy, we now support 15 PoC centers.




Later in the startup journey, we provide tailored incubation services, including hosting, technical support, and mentoring, through our ‘Innovation Booster’ program. Since its inception, the program has incubated more than 30 companies in France and India and we are now extending it to other countries.

Furthermore, we have an accelerator program, ST-UP, for technology startups. This is an 18-month, five-step program to support startups which have cutting-edge technology that can complement or augment existing ST solutions. The program was launched in Israel in 2018 and is now replicated in other countries, including France and Italy. It has so far accelerated more than 10 startups and is currently working with a further three (see I 103-3 I

Internal technology expertise


technical staff, including 32 Fellows

Around 8,100 ST employees work in R&D and product design. This includes nearly 750 members of our technical staff who are recognized for their advanced expertise. Within this community, we have 32 Fellows and nine Company Fellows, with three new Company fellowship nominations in 2020.

Our experts are extending their role and exposure by working closely with our Innovation Office and Fellows Scientific Committee. This community drives our most advanced innovation, enabling us to develop new technologies and helping to foster R&D partnerships with prestigious universities and partners worldwide.

Our sites around the world are also helping to nurture the entrepreneurial spirit of our employees through local innovation labs and hubs that help to connect our technical experts within the local ecosystem. We now have seven labs, with three new labs opened in 2020: the Acelab at our Tunis (Tunisia) site, and two Opus labs in Castelletto (Italy) and Catania (Italy).

In 2021, we plan to launch a global internal innovation challenge, open to all employees, which will include sustainability topics.
