Abstract
The focus of this paper is a comparative study of the advanced boron-based ultra-low energy (ULE) doping techniques on ultra-shallow junction (USJ) fabrications, including beam-line atomic 11B implant, BF2, B18H22, C2B10H12 molecular implants, cluster B implant, and B2H6 and BF3 PLAD implants. It has been found that B2H6 PLAD and B18H22 molecular implants demonstrate the best RS-xj and abruptness characteristics. Beam-line BF2 implant shows poor RS-xj characteristics due to its serious RIE effect by F species. Cluster B implant shows the worst RS-xj characteristics and a very rough surface. Both are attributed to its serious self-sputtering effect because of its much larger and heavier ion species although further optimization may lead to improvement.
