Latest Patents

Elnar holds a patent for a "Method for improving inversion layer mobility in a silicon carbide MOSFET." This patent describes a method of manufacturing a semiconductor device based on a SiC substrate. The process involves forming an oxide layer on a Si-terminated face of the SiC substrate at an oxidation rate sufficiently high to achieve 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-forming step. This method enables the manufacturing of a SiC-based MOSFET with improved inversion layer mobility and reduced threshold voltage. It has been observed that the density of deep traps increases while the density of near interface traps decreases when the Si-face of the SiC substrate undergoes rapid oxidation. The deep traps formed during this process can be effectively passivated by hydrogen annealing, leading to a significantly decreased threshold voltage for the semiconductor device.
