Course: Electronics and Telecommunications
Luca Morassi was born in Mirandola (Mo), Italy, on September 15th, 1982.
From July 2008 to February 2009 he was in IMEC (Interuniversity MicroElectronics Centre, Leuven, Belgium) for an internship; during this period he worked on the characterization of High-k-based composed stack for MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) gate oxide. In 2009 he received his academic master degree in Electronic Engineering from University of Modena e Reggio Emilia, Italy - Topic: "Characterization and Simulation of High-k Dielectrics for Innovative Non-Volatile Memories". During 2009 he collaborated with University of Modena and Reggio Emilia with a research activity focused on the electrical characterization of high-k material for Non-Volatile Memory (NVM) devices. Since 2010 he is a PhD student at ICT Electronics & Telecommunications Doctorate School, Modena, Italy with a research activity based on III-V compound semiconductor. His main research field is the characterization of InGaAs-channel MOSFETs and MOSHEMTs (Metal Oxide Semiconductor High Electron Mobilty Transistors) for high power and logic applications.
