On July 1st, 2025, the RePowerSiC consortium hosted a technical webinar titled “TCAD Modelling”, aimed at providing participants with an in-depth understanding of Technology Computer-Aided Design (TCAD) tools for the simulation and optimization of semiconductor devices. The event was held via Microsoft Teams and was led by Professor Antonio Garcia Loureiro from the Universidade de Santiago de Compostela, with the support of the RePowerSiC coordination team.

The webinar was introduced by the coordinator, Garcia Loureiro Antonio Jesus, who set the stage for a technical and engaging session. The main speaker was Javier Fernandez Lozano, a specialist in semiconductor device modelling.

The session opened with a comprehensive introduction to TCAD modelling. Professor Garcia Loureiro explained the structure and logic of TCAD simulations, focusing on how statement-based input files are used to define key parameters such as doping levels and material properties. Special attention was given to Silvaco Atlas, one of the main simulation tools used in the RePowerSiC project, including examples of how to write and organize simulation commands.

The webinar followed a structured format, which included:

• Introduction to TCAD Modelling
• Optimization Tools
• Practical Examples
• Q&A Session

The webinar continued with an overview of optimization tools and a series of practical examples that demonstrated real-world applications of TCAD in semiconductor device development. These examples helped bridge the gap between theoretical modelling and practical engineering.

A final Q&A session allowed attendees to engage directly with the speaker and clarify aspects of the presentation. Participants included researchers, engineers, and collaborators from across Europe.

This webinar was part of the dissemination and training activities of RePowerSiC, a project funded by the European Union’s Horizon Europe programme, which focuses on accelerating the development of energy-efficient Silicon Carbide (SiC) technologies for next-generation power electronics.
