This volume contains selected papers from the 12^th European Conference on Silicon Carbide and Related Materials (ECSCRM 2018), held in Birmingham, UK, in September 2018. Researchers discussed the latest progress in the field of silicon carbide semiconductors, including their development and production, and their application in the power electronic devices. The papers address silicon carbide growth, including bulk, epitaxial, and thin film growth; theory and characterization, including fundamentals and material properties, point and extended defects, and surfaces and interfaces; processing, focusing on doping, implantation, and contact, dielectric growth and characterization, and etching and machining; devices, including diodes, power MOSFETs, JFETs and IGBTs; reliability, circuits and applications. The contributors are academics and industrialists from around the world.
