Abstract
Dose rates were widely studied in ion implanter history due to the influence on semiconductor device performance. Several major parameters can be adjusted by dose rate, including implant damage, doping profile distribution, and doping activation. As devices shrink, ultra shallow surface doping becomes more significant on device performance. In this study, a special phenomenon of Boron distribution was investigated. Some parameters for dose rate tuning were also used to adjust the surface profile, which were potentially knobs for tuning device performance improvement.
