This paper studies the influence of thin oxide screening, layers on the formation of shallow junctions by low-energy B. implantation and rapid thermal annealing. For screening oxides, in the range from 0 to 10 nm, it is found that the trade-off between junction depth and sheet resistance (Psh) is not affected as long, as the implanted dose is adjusted to compensate for B trapping in the oxide. For a fixed implant dose and enengy, however, minute variations in the oxide, thickness have, a large infuence on Psh which limits the reproducibility of the junction formation process.
