5-3-3 System Benefits of High-Power High-Temperature SiC Devices Uncooled operation of high-temperature and high-power SiC electronics would enable revolutionary improvements to aerospace systems. Replacement of hydraulic controls and auxiliary power units with distributed “smart” electromechanical controls capable of harsh ambient operation will enable substantial jet-aircraft weight savings, reduced [...]
5-5 SiC Device Fundamentals To minimize the development and production costs of SiC electronics, it is important that SiC device fabrication takes advantage of existing silicon and GaAs wafer processing infrastructure as much as possible. As will be discussed in this section, most of the [...]
2-20.Linear Crystallographic Defects Crystalline solids exhibit a periodic crystal structure. The positions of atoms or molecules occur on repeating fixed distances, determined by the unit cell parameters. However, the arrangement of atom or molecules in most crystalline materials is not perfect. The regular patterns are [...]
2-31.N type A semiconductor has electrical conductivity between that of a conductor and an insulator. Semiconductors differ from metals in their characteristic property of decreasing electrical resistivity with increasing temperature.Semiconductors can also display properties of passing current more easily in one direction than the other, [...]
2-14.Masking Defects also referred to as “Mound” When one defect prevents the detection of another defect, the undetected defect is called the masked defect. A distinct raised area above the wafer frontside surface as viewed with diffuse illumination.
