Slovak technical university specializing in GaN/SiC power semiconductors, pilot line manufacturing, nuclear engineering, and smart energy systems.
Slovak University of Technology in Bratislava (STUBA) is Slovakia's leading technical university, specializing in semiconductor materials, power electronics, and GaN (gallium nitride) device development for energy-efficient applications. They operate pilot lines and testing facilities for wide band-gap semiconductor components, contributing to Europe's power electronics manufacturing capacity. Beyond semiconductors, they maintain strong capabilities in nuclear engineering education, building physics, and smart city energy systems. Their work bridges fundamental materials science with industrial-scale manufacturing, particularly in the electronic components and systems (ECS) value chain.
Central thread across PowerBase, OSIRIS, HiPERFORM, 5G_GaN2, UltimateGaN, REACTION, Power2Power, and R3-PowerUP — covering GaN packaging, SiC wafer pilot lines, and power electronics for 5G and electric mobility.
Active in pilot line projects including IoSense (sensor manufacturing), R3-PowerUP (300mm smart power), REACTION (SiC 8-inch wafer), and PowerBase (GaN pilot line).
Coordinated ENEEP (nuclear education platform), participated in EURAD (radioactive waste management), with keywords spanning thermal hydraulics, neutronics, and small modular reactors.
Contributed to MAKING-CITY (positive energy districts), CONNECT (smart home appliances), and PROGRESSUS (energy management with microgrids and charging infrastructure).
Participated in iRel40 (Intelligent Reliability 4.0) and PROGRESSUS, focusing on physics of failure, robustness validation, and trustworthy electronic components.
Involved in DiCoMI (directional composites and fibre reinforced polymers), FASTGRID (superconducting tapes), and INREP (indium-free transparent conductors).
In 2015–2018, STUBA focused on foundational semiconductor materials (indium-free electrodes, GaN substrate development, SiC substrates) and sensor pilot lines, establishing their position in Europe's power electronics supply chain. From 2019 onward, their work shifted toward application-driven projects — 5G base station components, electric mobility power conversion, smart grid integration, and reliability engineering for deployed electronic systems. A parallel thread in nuclear safety and education emerged in the later period, with STUBA coordinating ENEEP and joining EURAD.
STUBA is moving from materials research toward system-level integration of power semiconductors for electrification, 5G infrastructure, and energy management — making them increasingly relevant for industry partners needing proven GaN/SiC components at scale.
STUBA overwhelmingly operates as a consortium partner (38 of 44 projects), contributing specialized technical expertise rather than leading large initiatives. Their 4 coordinator roles are in nationally-anchored projects (SlovakION, GuEst, ENEEP) or smaller research actions. With 843 unique partners across 44 countries, they are a highly connected node in European R&D networks, particularly within the ECSEL Joint Undertaking ecosystem for electronics and semiconductor manufacturing.
STUBA has collaborated with 843 unique partners across 44 countries, reflecting deep integration into pan-European semiconductor and electronics consortia. Their network is especially dense in Western European industrial hubs (Germany, France, Netherlands) through ECSEL Joint Undertaking projects.
STUBA is one of very few Central European universities with continuous participation in Europe's semiconductor pilot line ecosystem (ECSEL projects), giving them hands-on experience with GaN and SiC manufacturing processes that most universities only study theoretically. Their combination of power electronics, nuclear engineering, and smart energy expertise is unusual — a consortium builder looking for a partner that can bridge semiconductor device physics with energy system applications will find few alternatives in the Visegrad region. As a Slovak institution, they also offer access to Widening Participation funding instruments.
