Logic and memory technologies face increasing complexity as continued scaling necessitates consideration of multiple physical processes to increase device, circuit and system reliability. This complexity drives the need for Design-Technology-Co-Optimization (DTCO) and System-Technology-Co-Optimization (STCO) approaches [1]. In these approaches, systems, circuits and devices are co-designed to improve performance and face critical development challenges. Emerging applications in machine learning acceleration and neuromorphic computing require sophisticated simulations that exploit extended regimes of device behavior, such as low-power operation at low voltages. Memory devices in particular lack adequate compact models, which are required for circuit simulation and design. Yet, the importance of memory devices and their compact models grows with Compute-In-Memory approaches, as SRAM and embedded DRAM scaling reach fundamental limits [2]. However, when used for computation, non-volatile memory (NVM) devices are facing serious reliability challenges due to endurance limitations that need to be modelled accurately [3].
In this talk we present Heracles [4], an efficient and dynamic compact model for ferroelectric HfO2 that enables analog and digital circuit simulations of both FeCap and FeFET devices with CMOS circuits. It further allows accurate modelling and simulation of variability and mismatch in both devices and circuits. This enables modelling of reliability phenomena and the exploration of their effects on the performance of memory circuits [5]. The physics-based model parameters are extracted using experimentally acquired characterization data and Technology Computer-Aided Design (TCAD) simulations. This allows direct correlation between reliability and scaling challenges with underlying material properties, such as parasitics or defects. In conclusion, our modeling framework provides essential tools for advancing ferroelectric memory technologies in next-generation computing architectures.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
