Abstract :
Physico-chemical and electrical investigations were carried out in 4H-SiC p-type layers created by aluminum ion implantation at room temperature and high temperature post-implantation annealing. Crystal recovery and dopant preservation after annealing are proved by RBS/C and SIMS measurements. Dopant activation is evaluate by sheet resistance measurements. These results were applied for high voltage bipolar diodes with JTE protection
