Latest Patents

Gudjonsson holds a patent for a method aimed at improving inversion layer mobility in silicon carbide MOSFETs. The patent describes a manufacturing process that involves forming an oxide layer on a Si-terminated face of the SiC substrate at a high oxidation rate. This process achieves a near interface trap density below 5×10^cm. Additionally, the oxidized SiC substrate is annealed in a hydrogen-containing environment to passivate deep traps formed during the oxide formation. This method enables the production of SiC-based MOSFETs with improved inversion layer mobility and reduced threshold voltage. The findings indicate that while the density of deep traps increases, the density of near interface traps decreases when the Si-face of the SiC substrate undergoes rapid oxidation. The passivation of deep traps through hydrogen annealing results in a significantly decreased threshold voltage for semiconductor devices formed on the oxide.
