International audienceMicroelectronic technologies have progressively shifted to nanotechnologies thanks to a permanent decrease in the size of elementary devices over the last 50 years. This evolution has been achieved by decreasing the lateral dimensions of the devices, and the thicknesses of the layers involved in the architecture of the devices. The minimum dimensions have today reached the size of several atoms. New concepts are introduced to better control the fabrication processes and, therefore, the electrical properties of circuits and systems. In parallel, the application spectrum of microelectronics has been broadened, which allows developing complete integrated systems such as connected objects, which also broadens the necessary...
