We have studied the effects of ion-channeling in B+ and As+ implanted Si which has been preamorphized to different depths by 28 Si+ irradiation at 60 keV and 180 keV. It is shown that the junctions for incompletely amorphized substrates are only slightly deeper than predicted by LSS theory. For preamorphized layers extending beyofnd-the predicted junction depths the implantations of 25 keV B+ and 120 keV 75As+ with a dose of 5-1015 cm-2 yield junction depths in the order of 2200-2300 Å after furnace annealing at 700°C for 30 minutes.
