Plasma region in high-fluence implants of phosphorus in amorphized silicon

Abstract
Phosphorus ions were implanted into silicon previously made amorphous by implantation with neon ions of projected range considerably greater than that of the P+ ions. Comparison of the annealing behavior for this case with that for P+‐only implants indicates that free‐carrier plasma formation in the region of high phosphorus concentration does not occur until the material has recrystallized.
