Abstract

Ion implantation of phosphorus (P) into 4H-SiC at room temperature and 500 °C was investigated. The P profiles simulated with a TRIM (transport of ions in matter) program showed good agreement with experimental results. The sheet resistance (R _s) of implanted layers at both temperatures decreased with increases in the annealing temperature between 1200 °C and 1600 °C. Also, in the case of the implanted layer at 500 °C, a low sheet resistance of 71 Ω/□ was obtained by annealing at 1600 °C. Hot-implantation was found to greatly improve the carrier concentration obtained by Hall-effect measurements. In the case of annealing at 1700 °C, the R _s of implanted layers at both temperatures increased sharply. From AFM analysis, it is thought that the increase in R _s is due to the sublimation or evaporation of SiC from the surface of the implanted layer.
