Silicon carbide (SiC) is more favorable than Silicon (Si) to build high voltage devices due its wider band-gap and higher critical field strength. Especially, the SiC MOSFETs are finding their
Silicon (Si)-based IGBTs have been on the market for more than 30 years. The technology has quickly evolved, reducing the costs and improving performance at the same time. As Si devices approach their physical limits, wide-band-gap devices, in particular made from silicon carbide (SiC), have emerged on the market, offering better performance thanks to their intrinsic properties.
silicon and carbon atoms in a hexagonal crystal struc-ture, there are two principal kinds of polytypes of silicon carbide: 6H-SiC and 4H-SiC. Before the intro-duction of 4H-SiC, the dominant polytype was 6H-SiC. Both types have been used for some years for
Impure and/or non-stoichiometric SiC, which may be referred to as SiC-based materials rather than SiC, is less stable in radiation environments than pure stoichiometric SiC. The primary reason is that the second phases, such as free metallic silicon, free carbon, silicon oxycarbide and metal oxide, are not as radiation stable as SiC ( Price and Hopkins, 1982; Hollenberg et al ., 1995 ).

SiC has been the gold standard of guide ring material for over 20 years. It''s the best heat dissipating ring in Fuji''s lineup and because of this, SiC Guides are particularly well suited for light drags and/or big fish. They diamond polish to a higher degree than any
In contrast, SiC-MOSFETs maintain a low on-resistance over a broad range. Moreover, at 150 , the slopes of the characteristic curves of both the SiC-MOSFET and Si-MOSFET are gentler, and so it is seen that the on-resistance increases. However, the SiC
