OSIRIS aims at improving substantially the cost effectiveness and performance of gallium nitride (GaN) based millimetre wave components. The project proposes to elaborate innovative SiC material using isotopic sources. This material will offer thermal conductivity improvement of 30% which is important for devices dissipating a lot of power, in particular in SiC power electronics and in microwave device using GaN high electron mobility transistors (HEMT) grown on SiC semi-insulating substrates.

OSIRIS aims at improving substantially the cost effectiveness and performance of gallium nitride (GaN) based millimetre wave components. The project proposes to elaborate innovative SiC material using isotopic sources. This material will offer thermal conductivity improvement of 30% which is important for devices dissipating a lot of power, in particular in SiC power electronics and in microwave device using GaN high electron mobility transistors (HEMT) grown on SiC semi-insulating substrates. OSIRIS project will allow reinforcing GaN technology penetration into the market by cost effectiveness of the SiC substrates and circuit performances improvement thanks to better heat spreading close to the dissipative area.
