Semefab UK has had a long history

Since the 1980s Semefab UK has had a long history in the manufacture of power semiconductor
products. The strategy is now to expand the power product offering with an exciting new
technology for SiC Schottky barrier diodes and IGBT devices for commercial product
manufacture starting in 2022 under the Semefab UK and Questsemi Australia brands.
The first product offered will be the SiC SBD using patented technology from Griffith University
Australia. This unique technology is proven to be extendible for voltages from 650V to 5000V
with the potential to extend this further.
The initial portfolio offered will be using the TO247 package or offered as wafer level bare die.
The Griffith University Homogeneous Current Schottky technology offers very high surge
current performance that increases with higher blocking voltages.
The design of the products can be readily changed to meet the customer requirements
regarding forward voltage and current rating. As the fabrication process is a lot shorter than
competitive products, custom products will be available for packaging within a few weeks. The
diodes can be attractively priced due to the low fabrication time and costs.
