Abstract :
The authors conclude that the measured boron dose loss was not due to surface sputter etching but rather back-scattering for zero degree tilt implantation and reflection for 45 degree tilt implantation. Increase in surface oxide thickness by as much as 0.9nm was detected for molecular B-dopant species. Highest retained dose was observed with hydrogen surface passivation especially for monomer B implantation and decreases with increasing surface oxide thickness.
