| Popis: | A comprehensive review of the features of silicon carbide (SiC) and various methods of deposition of gate oxides are presented in this report. The SiC material, which is mostly employed as base component in metal oxide semiconductor field effect transistors (MOSFETs) is very promising; for its high voltage, high power, high temperature and high breakdown field properties. These features have made it very attractive for use in power electronic devices over its counterparts in the field. Despite these great features, and the significant progress recorded in the past few years regarding the quality of the material, there are still some issues relating to optimization of the surface and interface processing. This review discusses the effect of surface modification and treatment as a means of enhancing the electrical performance of the SiC-based MOSFETs. It also identifies the challenges of controlling the density of dielectric/SiC interface trap that is needed to improve the values of mobility channels, and several oxidation techniques that could be used to surmount the structural limitations presently encountered by the SiO2/SiC system. Reliability as a significant aspect of electronic structures was also discussed with much emphasis on causes of their breakdown and possible solutions, especially in high thermal applications. |
