5-5-2 SiC-Selective Doping: Ion Implantation
The fact that diffusion coefficients of most SiC dopants are negligibly small (at 1800°C) is excellent for
maintaining device junction stability, because dopants do not undesirably diffuse as the device is operated
long term at high temperatures. Unfortunately, this characteristic also largely [...]
