Boron ion implantation into pre-amorphized silicon is studied. Pre-amorphization is performed either by F + or Si + implantation prior to B + implantation at 10 keV with 3 Â 10 15 ions/cm 2 . Broadening of the boron profile can be suppressed markedly in the pre-amorphized layers. For instance, the a
