Patent ID: 10262871

Abstract:
A method includes depositing a layer of silicon oxide onto a layer of silicon carbide; ion implanting the layer of silicon carbide, annealing the ion implanted layer of silicon carbide to produce defects within the layer of silicon carbide, performing photolithography using a mask layer on regions of the layer of silicon carbide to define regions for electrode deposition, removing the layer of silicon oxide from the layer of silicon carbide in the one or more regions for electrode deposition, forming one or more electrodes by depositing indium tin oxide (ITO) in each of the regions for electrode deposition, performing a first lift-off operation to remove the mask layer surrounding the electrodes, depositing a passivation and gate silicon oxide layer on top of the layer of silicon carbide and the electrodes, and performing a second lift-off operation to fabricate an optically transparent ITO gate between the electrodes.
