IMCRC activate funding helps lay foundation for SiC Schottky diodes manufacturing in Australia

Silicon carbide (SiC) Schottky diodes are small semiconductor devices – one-way electronic switches – used in many power conversion systems. Due to their incredible thermal conductivity, high switching performance and efficiency, they are highly sought-after for applications such as solar inverters, motor drives, electric vehicle (EV) chargers and uninterruptable power supplies.

A research collaboration led by Queensland Semiconductor Technology Pty. Ltd. (Questsemi) and Griffith University, supported by Semefab Scotland and the Innovative Manufacturing CRC (IMCRC), is currently establishing the manufacturability, performance, and characterisation of SiC Schottky diodes at a wafer level.

Using SiC wafers, researchers at the Queensland Microtechnology Facility (QMF) of Queensland Micro- and Nanotechnology Centre (QMNC) at Griffith University, have developed a new technology that allows for more efficient and low-cost fabrication of SiC diodes.
