Abstract
The characteristics of high-dose BF2 implantation at medium energy were investigated, focusing on the silicon crystal damage. In a BF2 70 keV 2 × 1015 ions/cm2, increase of sheet resistance (Rs) was observed for high beam current. A systematic study of increased wafer temperature during implantation was used to reduce implantation damage. The increased wafer temperatures reduced the Rs value to that obtained at lower beam currents.
