Abstract

Ion implantation profiles of boron after a BF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> plasma immersion ion implantation in a plasma implanter with a pulsed voltage ion extraction were investigated both experimentally and by means of numerical simulation. Boron profiles for different ion implantation doses in the range 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">15</sup> to 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">17</sup> cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> were measured using the SIMS method. Simulations were performed using a Monte-Carlo based binary-collision approach for ion implantation. A good reproduction of the measured boron profiles was obtained using a double-exponential energetic spectrum of the boron ions.
