Latest Patents

Halldor O Olafsson holds a patent for a method aimed at improving inversion layer mobility in silicon carbide MOSFETs. The patent describes a process that involves forming an oxide layer on a Si-terminated face of the SiC substrate at a high oxidation rate. This technique achieves a near interface trap density below 5×10^cm and includes annealing the oxidized SiC substrate in a hydrogen-containing environment. This process passivates deep traps formed during the oxide formation, resulting in a SiC-based MOSFET 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.
