SOCRATES - Driving the Electric Revolution with Wide Bandgap technologies

Power electronics, machines and drives (PEMD) supply chains play a critical role in the global decarbonisation effort and in achieving Net Zero targets. PEMD applications require robust devices that can operate at high voltages, temperatures and frequencies, as well as the ability to handle high current densities. Wide bandgap (WBG) semiconductor materials are ideally suited for such applications and allow for an increase in system efficiencies and reduction in weight and volume.

Compound semiconductor (CS) materials silicon carbide (SiC) and gallium nitride are frontrunners in the field of high-power devices and also identified as optimal WBG materials for trench-based vertical devices to increase device performance.

SOCRATES is a 9-month project which aims to address these opportunities in the UK PEMD supply chain. The consortium led by SPTS Technologies, a KLA company, also includes Newport Wafer Fab, Swansea University, Compound Semiconductor Centre and CSconnected and will deliver industrial processes for SiC and GaN trench etching, as well as additional chip fabrication processes for high volume manufacturing of wide band gap devices.
