patents filed

Thanks to our wide portfolio of patents and strong pipeline of innovation, we are one of the few semiconductor companies mastering a very broad range of chip manufacturing technologies. In 2022, we filed 597 patents, an increase of 10% on the previous year. See more details about our technologies on

In 2022, we announced the expansion of our operations in Catania (Italy) with an integrated silicon carbide (SiC) substrate manufacturing facility to be built alongside the existing SiC device manufacturing facility. SiC is a compound semiconductor material with intrinsic properties providing superior performance and efficiency over silicon. The facility will be the first of its kind in Europe for the volume production of 150mm and 200mm SiC epitaxial substrates, integrating all steps in the production flow. This development will support the needs of automotive and industrial customers in their shift to electrification and higher efficiency.

Artificial intelligence

ST is a leading provider of diversified software and hardware artificial intelligence (AI) solutions for tiny devices, such as sensors and microcontrollers.

Our AI solutions range from sensing, through embedded computing to actuation, supporting customers in shaping smarter products in sectors such as personal electronics, industrial, and automotive.

In 2022, we continued to develop our AI ecosystem by releasing multiple, incremental versions of STM32Cube.AI and NanoEdge AI Studio. STM32Cube.AI now supports Deeply Quantized Neural Networks (DQNN), a highly innovative feature that reduces the inference time and memory requirements of neural networks.

We also opened a new AI competence center specialized in the development and support of the NanoEdge AI Studio tool in Toulon (France). It adds to our other AI competence centers around the world. This is part of our ongoing efforts to simplify access to embedded AI technologies and their integration into industrial and consumer equipment.

Furthermore, to strengthen our early investment in the MLCommons Tiny working group that began in 2020, we became an official member of MLCommons. This open engineering consortium is dedicated to accelerating innovation in machine learning. It focuses on industry benchmarks, datasets, and best practices to accelerate the market adoption of tiny devices.

Launching our Intelligent Sensor Processing Unit

In 2022, we launched our Intelligent Sensor Processing Unit (ISPU), which combines a Digital Signal Processor (DSP) for AI algorithms and a MEMS sensor interface on the same silicon.

These smart sensors are able to sense, process and take action, offering seamless transactions with no discernible distinction between online and offline. ISPU also enables local decision-making, while substantially saving space and reducing power by up to 80%. This technology reflects the ‘Onlife Era’, where technology and everyday life come together.

AI training, machine learning, and the resulting neural network can run within the sensor itself. This enables ‘in-the-edge AI’ where, for example, smart inertial devices can perform advanced motion-detection functions within the sensor. This occurs without interaction with the external microcontroller and allows substantial power saving at the system level.

Innovation ecosystem

Recognizing the importance of partnerships in the innovation process, we build strategic alliances, engage in bilateral research cooperation, and participate in standardization bodies. Overall, we were involved in 186 active R&D partnerships in 2022.

External partnerships

We continued to develop our program of external partnerships. These bring together industry leaders from along the value chain to accelerate innovation, mainly in the automotive and industrial sectors, and diversify our scouting process in the smart mobility sector.

In 2022, the Important Project of Common European Interest (IPCEI) on Microelectronics successfully completed its technical activities in France. This was part of a French 5-year public-private strategic support program, called Nano 2022.

Thanks to Nano 2022, ST achieved major results in cutting-edge technologies for efficient computing, local data storage security, advanced connectivity, efficient power supply, novel and versatile optical sensors, efficient and faster data transmission, and connection. These technologies enable emerging applications in the automotive, IoT, industrial, security, space and aeronautics downstream markets.

The IPCEI program is still running in Italy, with additional objectives for technologies and products to be achieved by the end of 2024 on energy efficient chips, power semiconductors, and smart sensors.
