The aim of the course is to provide the theoretical basics to study materials and technologies for the design and the fabrication of microelectronic devices, micro and nanostructures and microsystems, with particular emphasis on applications in the ICT area. The course is focused around three main topics advanced FET transistor (FinFET, Tunnel FET, Gate All Around FET), post-transistor emerging technologies (Molecular and Atomic Devices, Magnetic Memories and Logic Devices, Resistive Memories) and microsystems (MEMS). The course of Nanoelectronic Systems is focused on the description of these systems and how they work, while the course of Technology for Nanoelectronic Systems describe the fabrication process of such systems. This course plays a central role in the development of an Engineer expert in micro and nanotechnologies, because it extensively provides the basic elements for the fabrication and design of the above mentioned systems.

Technology for Nanoelectronic Systems --------------------------------------------------------- Technology for MOS systems: - Advanced MOS processes; - 3D integration technology; - Heterogeneous integration technology; - Simulation of process workflow for MOS systems. Technologies for nanosystems: - Atomic Layer Deposition; - Atomic Layer Etching; - Techniques for single atoms/molecules manipulation. - Self-Assembly techniques; - Nanoimprinting; - Resistive and 3D memories. Technology for microsystems Nanoelectronic Systems -----------------------------------

Technology for Nanoelectronic Systems --------------------------------------------------------- The course is organized in theoretical lectures and laboratory exercises. The course topics will be described considering some relevant cases of study: - FinFet/Tunnel Fet; - MEM sensors; - Molecular/Atomic circuits; - Magnetic Hard Drives; - Self-Assembled systems; - Resistive memories. For each of them will be analyzed the technological processes used for the integration in pervasive nanosystems which will be of high added values for many applications. The classes will be ONLY online for the 2020/2021 academic year. The laboratory exercises are instead focus on the simulation of the process workflow for MOS circuits. Finite element simulators able to simulate all fabrication processes used for planar circuits will be used to emulate all fabrication steps of a device. The laboratory can be done online, onsite or partially online and onsite. Nanoelectronic Systems -----------------------------------

Lectures notes will be provided to the students by the teachers as an integration to the lessons.

Modalità di esame: Prova orale obbligatoria; Elaborato scritto prodotto in gruppo;

Exam: Compulsory oral exam; Group essay;

... The exam consists in two parts. 1) Laboratory reports: The laboratories will require a report on each subject and will be evaluated for the final exam (25%). 2) Oral exam: The oral exam will be on the whole subject (75%). Exam rules - Laboratory reports: A single report describing all the laboratories must be delivered before the end of January. For each of the four laboratories the report must describe the design of the device complete with all the choices done, how the device was implemented within the simulation environment and the results obtained. Laboatory reports are expected to be complete and well presented and connected to the theory analyzed in the lectures. Critical thinking will be especially evaluated. Laboratory reports are evaluated over a maximum score of 30 Lode. -Oral exam: the exam is based on three to six questions on the whole subject. During the oral exam the students will be evaluated based on the following objectives: - Knowledge of the structure and fabrication of advanced MOS devices; - Knowledge of fabrication processes for beyond CMOS systems; - Knowledge of MEMS technology for sensors; - Knowledge of fabrication processes simulations tools and activities carried on during the laboratories. The oral exam is evaluated over a maximum score of 30 Lode. The final mark will be calculated using a weighted sum of the laboratory and oral part.
